Depression in older people: visual impairment and subjective ratings of health

A Prospective Association Between Sensory Impairment and Cognitive Performance Among Older Community-Dwelling Adults: The Role of Depressive Symptoms

We examined whether vision impairment (VI) and hearing impairment (HI) and dual sensory impairment (DSI) affect cognitive performance and whether depression mediates that effect. We examined 55,340 participants from the Survey of Health, Aging and Retirement in Europe, which assessed 32,325 participants in 2011 (baseline, Time 1), 2015 (follow-up, Time 2), sociodemographic data and health factors, self-reported VI, HI, and DSI at baseline, depression, and cognitive performance after four years. A multiple mediator model was tested using bootstrapping and resampling. At baseline, 22.9% had VI, 10.2% HI, and 10.4% had DSI. We found a significant negative association between VI (b = -0.023, p = .001) and DSI (b = -0.083, p = .001) and cognitive performance; both were also associated with depression, which was linked with poor cognition. VI or DSI among older adults are associated with poor cognitive function directly and indirectly by increasing depression symptoms.

Perspectives of Patients and Professionals on Implementing a Computer Adaptive Vision-Related Quality of Life Outcome (CAT-EyeQ) in Clinical Practice

Purpose

The CAT-EyeQ is a computer adaptive test (CAT) which measures vision-related quality of life in patients having exudative retinal diseases. The aim of this study is to investigate the usability of the CAT-EyeQ in clinical practice and identify potential barriers and facilitators for implementation (problem analysis).

Methods

Patients and health care professionals participated in the study regarding the usability of the CAT-EyeQ, and clinic managers and health care professionals were included in the problem analysis for implementation. In total, we conducted 18 semi-structured interviews. The Consolidated Framework for Implementation Research (CFIR) was used to develop the interview guides and to structure results.

Results

Six themes were derived from the usability study and problem analysis: (1) quality of the CAT-EyeQ and the applicability to patients' needs and preferences, (2) embedding the CAT-EyeQ in current practice, (3) implementation climate of the eye hospitals, (4) attitude of professionals, (5) engaging and encouraging professionals, and (6) integration of the CAT-EyeQ in health care - needs after piloting.

Conclusions

Patients and professionals mentioned that the CAT-EyeQ improved insight into the impact of eye diseases on a patient's daily life, it allowed for more attention on the patient perspective and the structured measurement of vision-related quality of life. The main perceived barriers mentioned by professionals for using the CAT-EyeQ were lack of time and the integration of the patient-reported outcome measure (PROM) results within the electronic patient record (EPR).

Translational Relevance

The CAT-EyeQ, accompanied by an overview of stakeholder perspectives resulting from this implementation study, can now be used in clinical practice.

The association between visual impairment and mental disorders

To determine the association between visual impairment (VI) and some mental disorders using the general health questionnaire (GHQ) in individuals aged 60 years and above in Tehran, Iran. The present population-based cross-sectional study was conducted on people aged 60 and older in Tehran, Iran using multi-stage cluster sampling. After selecting the samples, examinations including visual acuity measurement, refraction, and slit-lamp biomicroscopy were performed for all participants. The GHQ was used to examine mental disorders. Simple and multiple linear regressions were used to investigate the association between VI and mental disorders. Of the 3740 invitees, 3310 participated in the study (response rate: 88.50%). After applying the exclusion criteria, 2789 individuals were analyzed for this report. Mean score of physical, anxiety, social and depression disorders in people with and without VI was 3.74 ± 2.03, 5.81 ± 2.79, 7.56 ± 1.91, 1.32 ± 1.90, and 3.14 ± 1.76, 4.93 ± 2.71, 8.09 ± 1.99, 0.91 ± 1.38, respectively. The total score of GHQ in participants with and without VI was 18.43 ± 4.75 and 17.07 ± 4.19, respectively. The association between GHQ subscales and total GHQ score with VI by multiple linear regression showed that VI had a statistically significant direct association with physical symptoms (β = 0.37; 95% CI 0.12 to 0.62) and anxiety (β = 0.48; 95% CI 0.16 to 0.81). Nevertheless, depression had a borderline association with VI (β = 0.21; 95% CI - 0.03 to 0.45) and social dysfunction did not have a statistically significant association with VI in the final linear regression model and did not remain in the model. Total GHQ score had a statistically significant association with VI (β = 1.02; 95% CI 0.39 to 1.64) in the presence of covariates. Regarding the association between VI and GHQ components, the physical symptoms had the highest R2 (R2 = 0.159). Patients with VI suffer more from anxiety, depression, and physical symptoms regardless of age, sex, education, and other effective variables. The coincidence of aging with VI and the association of VI with mental disorders emphasizes the importance of a broader view of the elderly and the aging process.

United States Population Disparities in Ophthalmic Care: Blindness and Visual Impairment in the IRIS® Registry (Intelligent Research in Sight)

PURPOSE

To evaluate associations of patient characteristics with United States eye care use and likelihood of blindness.

DESIGN

Retrospective observational study.

PARTICIPANTS

Patients (19 546 016) with 2018 visual acuity (VA) records in the American Academy of Ophthalmology's IRIS® Registry (Intelligent Research in Sight).

METHODS

Legal blindness (20/200 or worse) and visual impairment (VI; worse than 20/40) were identified from corrected distance acuity in the better-seeing eye and stratified by patient characteristics. Multivariable logistic regressions evaluated associations with blindness and VI. Blindness was mapped by state and compared with population characteristics. Eye care use was analyzed by comparing population demographics with United States Census estimates and proportional demographic representation among blind patients versus a nationally representative US population sample (National Health and Nutritional Examination Survey [NHANES]).

MAIN OUTCOME MEASURES

Prevalence and odds ratios for VI and blindness; proportional representation in the IRIS® Registry, Census, and NHANES by patient demographics.

RESULTS

Visual impairment was present in 6.98% (n = 1 364 935) and blindness in 0.98% (n = 190 817) of IRIS patients. Adjusted odds of blindness were highest among patients ≥ 85 years old (odds ratio [OR], 11.85; 95% confidence interval [CI], 10.33-13.59 vs. those 0-17 years old). Blindness also was associated positively with rural location and Medicaid, Medicare, or no insurance vs. commercial insurance. Hispanic (OR, 1.59; 95% CI, 1.46-1.74) and Black (OR, 1.73; 95% CI, 1.63-1.84) patients showed a higher odds of blindness versus White non-Hispanic patients. Proportional representation in IRIS Registry relative to the Census was higher for White than Hispanic (2- to 4-fold) or Black (11%-85%) patients (P < 0.001). Blindness overall was less prevalent in NHANES than IRIS Registry; however, prevalence in adults aged 60+ was lowest among Black participants in the NHANES (0.54%) and second highest among comparable Black adults in IRIS (1.57%).

CONCLUSIONS

Legal blindness from low VA was present in 0.98% of IRIS patients and associated with rural location, public or no insurance, and older age. Compared with US Census estimates, minorities may be underrepresented among ophthalmology patients, and compared with NHANES population estimates, Black individuals may be overrepresented among blind IRIS Registry patients. These findings provide a snapshot of US ophthalmic care and highlight the need for initiatives to address disparities in use and blindness.

Factors associated with health-related quality of life among people with visual impairments living in nursing homes in Armenia: a cross-sectional study

PURPOSE

The study aimed to examine the effect of visual impairment (VI), eye diseases, and other risk factors on health-related quality of life (HRQoL) in nursing home residents in Armenia.

METHODS

This cross-sectional study administered an interviewer-administered structured questionnaire to collect information about socio-demographics, chronic diseases, HRQoL, smoking, receiving and giving instrumental/emotional social support, and sleeping disorders among 313 nursing home residents. An ophthalmic examination of the participants was conducted.

RESULTS

The mean age was 72.5 years, ranging from 45.5 to 91.4. Women constituted 50% of the sample. The prevalence of normal vision by presenting visual acuity with available correction was 55.3%, while VI and blindness were present in 40.8% and 3.9%, respectively. Uncorrected refractive error (URE) was found in 20% of participants. The mean HRQoL score was 51.3, ranging from 7.9 to 95.0. In the adjusted analysis, having at least one chronic non-communicable disease, sleeping disorders, eye diseases, URE, VI, blindness, and giving instrumental social support were associated with HRQoL.

CONCLUSIONS

Regular eye care services could improve the eye health and HRQoL of nursing home residents. Interventions addressing vision loss and chronic non-communicable diseases could enhance the functioning and overall well-being of the target population.

Psychiatric aspects of ophthalmic disorders: A narrative review

Ophthalmic disorders have psychiatric aspects associated with them at various levels. Psychological factors have a well-documented role in the causation, aggravation, and maintenance of various ophthalmic conditions, including glaucoma, central serous retinopathy, dry eye disease, and retinitis pigmentosa. Many ophthalmic conditions, including blindness, have psychological manifestations as well, which need to be addressed, in addition to the ophthalmic pathology. There is also significant overlap in the treatment of the two disciplines in many ways. For instance, many ophthalmic drugs have psychiatric side effects. Even ophthalmological surgeries have psychiatric aspects associated with them, which primarily include black patch psychosis and anxiety in the operation theater. This review will be useful for psychiatrists and ophthalmologists, for their clinical practice and research. Future research should focus on this interface to give it its well-deserved attention.

Needed adaptations in psychological treatments for people with vision impairment: A Delphi study, including clients, relatives, and professionals

Objective

In this study, we aimed to identify the themes that should be addressed when adapting mental health treatments for adults with a visual impairment.

Method

A Delphi study was conducted among 37 experts, including professionals, persons with a visual impairment, and relatives of clients with a visual impairment.

Results

The Delphi consultation revealed seven categories (factors) that were identified as important in the treatment of mental health problems for clients with a visual impairment: the visual impairment, environment, stressors, emotions, the professional's role and attitude, treatment setting, and accessibility of materials. Factors regarding the clients' visual impairment, such as the severity of the impairment, influence the extent to which adjustments are needed in treatment. During treatment, the professional plays an important role in explaining any visual elements that a client with a visual impairment may miss.

Conclusion

In psychological treatment, clients require individual adaptations for their specific visual impairment.

Impact of Age-Related Macular Degeneration and Related Visual Disability on the Risk of Depression: A Nationwide Cohort Study

PURPOSE

To evaluate the prospective association of age-related macular degeneration (AMD) and related visual disability (VD) with the risk of depression.

DESIGN

This nationwide population-based cohort study used authorized clinical data provided by the Korean National Health Insurance Service.

PARTICIPANTS

A total of 3 599 589 individuals older than 50 years participated in the Korean National Health Screening Program in 2009.

METHODS

Age-related macular degeneration diagnosis and the presence of accompanying VD were verified using diagnostic codes and disability registration data. Data on covariates, including age, sex, income level, residential area, systemic comorbidities, and behavioral factors, were collected from health screening results and claims data. Patients were followed up until December 2019, and incident cases of depression were identified using registered diagnostic codes. The prospective association of AMD and related VD with new-onset depression was investigated using the multivariable-adjusted Cox proportional hazard model.

MAIN OUTCOME MEASURES

Hazard ratios and 95% confidence intervals (CIs) for depression development according to the presence of AMD and VD.

RESULTS

During an average follow-up period of 8.52 years, 1 037 088 patients received new diagnoses of depression. Patients with previous diagnoses of AMD showed a greater risk of new-onset depression, with a hazard ratio of 1.15 (95% CI, 1.13-1.17) compared with the control group in the fully adjusted model. Patients with AMD and accompanying VD showed a further increased risk of depression, with a hazard ratio of 1.23 (95% CI, 1.16-1.30).

CONCLUSIONS

Individuals with a diagnosis of AMD have a higher risk of depression developing in the future. The risk of depression is increased further in patients with AMD who demonstrate VD.

Depression among Older Adults in Indonesia: Prevalence, Role of Chronic Conditions and Other Associated Factors

Background

Depression is one of the most common illnesses worldwide, with a prevalence of 5.7% among older adults aged over 60. Depression is a severe health condition that can significantly affect the quality of life.

Objective

The objective of this study is to investigate the determinant factors of depression among older adults in Indonesia.

Methods

Data of 4236 adults of 60 years old and over were taken from the fifth wave of the Indonesian Family Life Survey (IFLS-5). Sociodemographic and multiple health-related variables collected through interviews and measurements were analyzed. Multivariate logistic regression was used to evaluate depression and its associated factors.

Results

The prevalence of depression assessed using ten questions from the Center for Epidemiologic Studies Depression Scale (CES-D 10) was 16.3%. Significant associated factors for depression were moderate and low subjective economic status, living in Java or other regions outside Sumatra and Java, no life satisfaction, self-perceived as having poor health, having dependency (IADL scores), and experienced falls and insomnia. Among chronic conditions, stroke, arthritis, and hearing impairment were also more common in depressed older adults.

Conclusion

Predictors of depression identified in this study may be used to help prevent and improve depression in Indonesian older adults, especially those who live on Java. Improvement in healthcare, especially in the prevention and rehabilitation of stroke, arthritis, possible frailty (falls and dependency), hearing impairment, and insomnia, concurrent with early detection of depression in these chronic conditions, may help create a better quality of life among Indonesian older adults.

Personality and limitations in instrumental activities of daily living in old age: Reciprocal associations across 12 years

Personality traits have been reported to predict difficulties in performing instrumental activities of daily living (IADL) in old age, such as preparing meals or shopping. However, little is known about the reciprocal effects on personality. In this study, we examined bidirectional relationships between personality traits and the capacity to perform IADL using four waves of longitudinal data from 3540 older adults (aged 65 years and older) from the Health and Retirement Study. We applied a random-intercept cross-lagged panel model to separate between- and within-person effects across time and compared it to a traditional cross-lagged panel model. At the between-person level, higher neuroticism and lower conscientiousness were associated with more IADL limitations. Within individuals across time, increases in neuroticism and decreases in conscientiousness and extraversion were associated with increases in IADL limitations 4 years later. In contrast, increases in IADL limitations only predicted increases in neuroticism and decreases in extraversion. These results indicate that some personality traits affect and are affected by limitations in functional capacities in old age. Results of the within-person model build a strong foundation for future personality interventions as a pathway to maintain high functioning in old age.

Prevalence, causes, and impact of self-reported vision impairment among older people in China: Findings from the China health and retirement longitudinal study

This article investigated the prevalence, causes, and impact of self-reported vision impairment among older people in China. A total of 12,910 participants aged ⩾50 years were included in this study from China Health and Retirement Longitudinal Study (CHARLS) over the periods of 2011, 2013, and 2015. All data were reported by participants via a self-reported questionnaire. Distance vision was assessed by asking if they could see the face of a person on the other side of the street. Near vision was assessed by asking if they could read ordinary newspaper. Depressive symptoms were evaluated by 10-item Center for Epidemiological Studies Depression Scale. The analysis method included the χ2 – square distribution test and multiple regression analysis. This article first found that prevalence of self-reported vision impairment was much higher in rural than in urban areas; in urban areas, females had a greater chance of being affected than males, and for both sexes, it increases with increasing age. Second, some factors found are significantly associated with increased vision impairment rates, include increasing age, female gender, rural residents, elementary-level education, unmarried individuals, and non-agricultural occupations. Third, the leading cause of vision impairment was a refractive error and the most common causes of vision impairment include cataracts and glaucoma. Fourth, vision impairment was significantly associated with falls and depressive symptoms and has a negative effect on the quality of life of older Chinese. The article concluded that older people with self-reported vision impairment were relatively low and it is majorly caused by refractive error. Older people with distance vision impairment and near vision impairment were more likely to report falls and depressive symptoms in the future. In line with these findings, a couple of policy recommendations for further research were made.

Calibration of the Dutch EyeQ to Measure Vision Related Quality of Life in Patients With Exudative Retinal Diseases

Purpose

This study aims to develop an item-bank to measure vision-related quality of life (Vr-QoL) and subsequently calibrate this set of items.

Methods

Three Vr-QoL instruments were searched for suitable items to be added in the EyeQ. Patients who received antivascular endothelial growth factor treatment for various retinal diseases involving macular edema were included in the study and completed the 47-item EyeQ. Item response theory (IRT) was used to calibrate the EyeQ items, which was performed multiple times in subsets as a novel approach, containing 80% of the data. Differential item functioning (DIF) was evaluated for various variables.

Results

Responses of 704 patients were used in analysis. One item violated the local independence IRT-assumption and showed a high percentage of missing values, after which this item was deleted from the item-bank. The data of the five subsets fitted the graded response model adequately, and no DIF was detected for items between subsets, after which mean item parameters were calculated. Item fit statistics were found to be good. DIF was detected for gender, age, and administration mode by the patient (independently vs. with help), this involved three items, which all showed negligible impact on total scores.

Conclusions

Because of separate calibrations of the EyeQ in multiple subsets, a high robustness of item parameters is expected.

Translational Relevance

The calibrated EyeQ can now be used for the assessment of Vr-QoL in patients suffering from exudative retinal diseases and is promising for use as a computer adaptive test.

Self-Reported Vision Impairment and Psychological Distress in U.S. Adults

PURPOSE

Examine the relationship between vision impairment and psychological distress in adults ≥18 years.

METHODS

Using the 2016-2017 cross-sectional, U.S. National Health Interview Survey, we analyzed self-reported data (n = 57,644) on: Kessler psychological distress scores; general vision impairment (GVI), defined as difficulty seeing even when wearing glasses or contacts; and visual function impairment (VFI), measured using six visual function questions. Multinomial logistic regression was used to estimate adjusted odds ratios (aOR) for mild/moderate and serious psychological distress, by GVI and VFI status, and identify predictors of psychological distress among those with GVI or VFI.

RESULTS

Among adults, 10.6% (95% CI: 10.2, 11.0) had GVI; 11.6% (CI: 11.1, 12.0) had VFI. One in four adults with GVI had psychological distress (14.9% [CI: 13.8, 16.0] reported mild/moderate and 11.2% [CI: 10.2, 12.3] reported serious). Individuals with GVI, versus those without, had higher odds of mild/moderate (aOR = 2.24; CI: 2.00, 2.52) and serious (aOR = 3.41; CI: 2.96, 3.93) psychological distress; VFI had similar findings. Among adults with GVI, odds of serious psychological distress were higher for those aged 18-39 (aOR = 4.46; CI: 2.89, 6.90) or 40-64 (aOR = 6.09; CI: 4.33, 8.57) versus ≥65 years; smokers (aOR = 2.45; CI: 1.88, 3.18) versus non-smokers; physically inactive (aOR = 1.61; CI: 1.22, 2.11) versus active; and with arthritis (aOR = 2.18; CI: 1.66, 2.87) or chronic obstructive pulmonary disease (aOR = 1.65; CI: 1.15, 2.37) versus without.

CONCLUSION

Adults with self-reported vision impairment had higher odds of psychological distress. These findings may inform screening interventions to address psychological distress, particularly among younger working-age adults vision impairment.

Midlife Vision Impairment and Cognitive Function in Later Life: The Study of Women's Health Across the Nation, Michigan Cohort

BACKGROUND

In older adults, vision impairment (VI) is associated with worse cognitive function. However, the relationship between midlife vision and future cognitive function remains unknown.

METHODS

The Study of Women's Health Across the Nation, Michigan site, is a longitudinal cohort of midlife women aged 42-52 years at baseline. Presenting Titmus visual acuity (VA) in the better-seeing eye was assessed at baseline and categorized as no or mild VI (VA ≥20/60), or moderate or worse VI (VA <20/60). Cognitive function was measured 8 times over 15 years using the East Boston Memory Test immediate (EBMTi) and delayed (EBMTd) recall and the Digit Span Backwards (DSB) test. Linear mixed models with a random intercept and slope for age were constructed to detect associations between VI at baseline and future repeated measures of cognitive function, adjusting for age, race, education, financial strain, alcohol use, and tobacco use.

RESULTS

About 394 women aged 42-52 at baseline with a maximum follow-up of 20 years were included in this analysis. After covariate adjustment, moderate or worse VI was associated with lower EMBTi (β = -0.56, p = .012), EBMTd (β = -0.60, p = .009), and DSB (β = -0.84, p = .04). While we detected significant associations between VI and levels of cognitive function scores, rates of cognitive decline as individuals aged did not vary by VI status.

CONCLUSION

Moderate or worse VI, assessed during midlife, was associated with lower scores on measures of cognitive function over a 15-year period during which women transitioned from midlife to older adulthood.

Longitudinal association of midlife vision impairment and depressive symptoms: the study of Women's Health Across the Nation, Michigan site

OBJECTIVE

Poor vision affects physical health but the relationship with depressive symptoms among midlife adults (40-65 y), who often present with early stage vision impairment (VI), is not well understood. The goal of this study was to assess the impact of vision on depressive symptoms during midlife.

METHODS

The Michigan site of the Study of Women's Health Across the Nation conducted assessments of distance visual acuity at six consecutive, near-annual follow-up visits. At each visit, depressive symptoms (Center for Epidemiological Studies-Depression Scale) were assessed. VI was defined as mild (20/30-20/60) or moderate-severe (20/70 or worse). Multivariable logistic regression models using generalized estimating equations were used to assess the association of VI and reporting of depressive symptoms at the subsequent visit.

RESULTS

At analytic baseline, the mean age of participants (N = 226) was 50.0 years (standard deviation = 2.6). More than half (53.5%) of women had mild VI and 8.0% had moderate-severe VI. Adjusting for age, preexisting depressive symptoms, race, education, economic strain, body mass index, and smoking, participants with mild and moderate-severe VI had 68% (95% C (0.97-2.90)) and 2.55-fold (95% CI 1.13-5.75) higher odds of reporting depressive symptoms at their subsequent study visit as compared with women without VI. Further adjustment for diabetes, hypertension, and osteoarthritis attenuated the estimates and the associations were no longer statistically significant.

CONCLUSION

VI was associated with increased odds of future depressive symptoms among mid-life women. Timely detection and appropriate correction of VI may be important to consider in maintaining the mental health status of midlife women.

Vision-Related Quality Of Life And Depression In Brazilian Patients With Toxoplasmic Retinochoroiditis

PURPOSE

To investigate visual-related quality of life (VRQL) and prevalence and severity of depressive symptoms in Brazilian individuals with toxoplasmic retinochoroiditis (TRC).

DESIGN

Comparative observational cross-sectional study. The National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) and Beck Depression Inventory-II (BDI-II) were applied to respectively assess VRQL and depression in individuals consecutively seen at a uveitis referral center. Clinical/demographical data were collected. Descriptive/analytic statistics were employed, with P<0.05.

RESULTS

Patients and controls were comparable concerning age, sex and socioeconomic level. VRQL scores for all subscales were significantly lower in TRC when compared with controls, particularly associated (P<0.05) with female sex, history of ≥2 prior TRC recurrences, concomitant use of systemic corticosteroids, monocular vision and blindness. Depressive symptoms were more prevalent in TRC (55/188; 29.2%) than in controls (34/182; 18.7%) (P=0.023), also being associated with lower VRQL scores (P<0.001). Seropositive and seronegative controls for toxoplasmosis had similar VRQL scores and comparable rates of depressive symptoms.

CONCLUSION

TRC affects VRQL in Brazilian individuals, particularly women, using systemic corticosteroids, with visual impairment and presenting recurrences of TRC. One-third of patients with TRC had evidence of depression, which was also associated with lower VRQL scores. Mental health issues in subjects with TRC should not be overlooked.

Association of vision loss and depressive symptomatology in older adults assessed for ocular health in senior living facilities

PURPOSE

People with vision loss are at increased risk for major depressive disorder (MDD) and subclinical depression. However, screening for depression is rarely done in eye care settings or among groups in the general population known to have vision disorders.

METHODS

We examined the prevalence of depression, using the Patient Health Questionnaire - 2 (PHQ-2), among a group of older adults (N = 204; mean age = 82.15) at two senior living facilities (SLFs) and determined the relationships between severity of depression and objective visual findings, visual function, beliefs about taking an active role in one's own eye care (i.e., patient activation) and level of social support.

RESULTS

Approximately 50% of the sample had impaired vision in at least one eye, and close to 30% of the sample obtained a score on the PHQ-2 indicating the likely presence of major depressive disorder. Visual testing findings were related to visual function (e.g., ability to read), but not to depression. Patient activation was also not significantly related to the level of depression. However, impaired visual functioning and less social support were both strong predictors of depression. These two variables and their interaction accounted for 17% of the total PHQ-2 score variance.

CONCLUSIONS

These data indicate the potential utility of screening for depression as part of vision care in populations likely to have significant vision loss. The findings also suggest that a comprehensive approach to depression prevention and/or reduction in SLF and similar populations may require interventions to address reduced visual functioning and methods to strengthen social networks.

Depression among attendants of the Sudanese National Association of the Blinds in Khartoum, Sudan

Background

Blindness has profound consequences for the victim, family, and society. The impact of vision loss on daily life activities could lead to psychological stress. Early treatment of depression may reduce the added disability that is associated with vision loss. This study aimed to assess the extent and associated factors with depression among the Sudanese blind people in Khartoum, Sudan. A cross-section facility-based study was conducted, in which depression among the participants was assessed using the Beck Depression Inventory Scale. A chi-square test was implemented to determine the relationship between categorical variables and the significance level for all analyses was set at p < 0.05.

Results

A total of 185 participants were included in the study. Out of them, 84.3% were male and near half of the participants (42.2%) were born blind. The prevalence of depression among the participants was 11.4%. There were significantly higher rates of depression in those who were illiterate (χ2 = 6.233, p = 0.044) and in those whose loss of vision was due to accidents or traumatic causes and loss of vision due to accidents or traumatic causes (χ2 = 12.840, p = 0.002). There was significantly lower rate of depression in those who were born with blindness compared to others (χ2 = 10.504, p = 0.005).

Conclusions

People who were born blind have a lower rate of depression and people who lost their sight due to trauma have a higher rate of depression, and therefore, requiring more psychiatric support. Despite the relatively low percentage of depression, establishing programs for early identification and combating depression among the blind population in our setting is highly recommended.

Association Between Visual Impairment and Depression in Patients Attending Eye Clinics: A Meta-analysis

IMPORTANCE

Given that depression is treatable and some ocular diseases that cause visual loss are reversible, early identification and treatment of patients with visual impairment who are most at risk of depression may have an important influence on the well-being of these patients.

OBJECTIVE

To conduct a meta-analysis on the prevalence of depression in patients with visual impairment who regularly visit eye clinics and low vision rehabilitation services.

DATA SOURCES

MEDLINE (inception to June 7, 2020) and Embase (inception to June 7, 2020) were searched.

STUDY SELECTION

Studies that obtained data on the association between acquired visual impairment and depression among individuals aged 18 years or older were identified and included in this review. Exclusion criteria comprised inherited or congenital eye diseases, review studies, unpublished articles, abstracts, theses, dissertations, and book chapters. Four independent reviewers analyzed the results of the search and performed the selection and data extraction to ensure accuracy.

DATA EXTRACTION AND SYNTHESIS

Meta-analyses of prevalence were conducted using random-intercept logistic regression models. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

MAIN OUTCOMES AND MEASURES

Proportion of depression.

RESULTS

A total of 27 studies were included in this review, and all but 2 included patients older than 65 years. Among 6992 total patients (mean [SD] age, 76 [13.9] years; 4195 women [60%]) with visual impairment, in 1687 patients with depression, the median proportion of depression was 0.30 (range, 0.03-0.54). The random-effects pooled estimate was 0.25 (95% CI, 0.19-0.33) with high heterogeneity (95% predictive interval, 0.05-0.70). No patient characteristic, measured at the study level, influenced the prevalence of depression, except for the inclusion of patients with cognitive impairment (0.33; 95% CI, 0.28-0.38 in 14 studies vs 0.18; 95% CI, 0.11-0.30 in 13 studies that excluded this with major comorbidities; P = .008). The prevalence of depression was high both in clinic-based studies (in 6 studies, 0.34; 95% CI, 0.23-0.47) and in rehabilitation services (in 18 studies, 0.25; 95% CI, 0.18-0.33 vs other settings in 3 studies, 0.15; 95% CI, 0.05-0.38; P = .17), and did not vary by visual impairment severity of mild (in 8 studies, 0.24; 95% CI, 0.14-0.38), moderate (in 10 studies, 0.29; 95% CI, 0.21-0.39), and severe (in 5 studies, 0.29; 95% CI, 0.12-0.56; P = .51).

CONCLUSIONS AND RELEVANCE

The results of this meta-analysis suggest that depression in patients with visual impairment is a common problem that should be recognized and addressed by the health care professionals treating these patients.

Anxiety and depression in patients who receive anti-VEGF treatment and the usability and feasibility of e-mental health support: the E-PsEYE pilot study

Purpose

E‐PsEYE is an internet‐based, guided self‐help course, following the principles of cognitive behavioural therapy, to reduce anxiety and depression in patients with retinal exudative diseases who receive anti‐vascular endothelial growth factor (anti‐VEGF) treatment. The purpose of this study was to determine the prevalence and related factors of anxiety and depression in this population and evaluate the usability and feasibility of E‐PsEYE.

Methods

Symptoms of anxiety and depression and related factors were determined in 90 patients (mean age 77 years, 58% female), based on multiple logistic regression analysis. Five patients with mild to moderate depression/anxiety tested the usability of E‐PsEYE. They were asked to think aloud while completing two modules of the intervention and freely explore system features. The feasibility of the total E‐PsEYE intervention was tested in 14 patients with mild to moderate depression/anxiety, based on a single arm pre‐post study with a follow‐up of three months: fidelity, acceptability, feasibility of study methods and potential effectiveness were explored.

Results

Fifty‐three percent of the total study population experienced at least mild anxiety and/or depression symptoms. Especially female patients (odds ratio (OR) 3.89, 95% confidence interval (CI) 1.33–11.40), those who experienced limitations in daily life activities due to vision loss (OR 9.67; 95% CI 3.18–29.45) and those who experienced loneliness (OR 3.53, 95% CI 1.14–10.95) were more likely to have anxiety/depression. The usability study raised several possibilities for improvement, based on which E‐PsEYE was improved. The feasibility study showed adequate fidelity and acceptability. Most participants were satisfied with the results (79%). There was a high response rate, no loss to follow‐up and mental health problems decreased in more than half of the patients. The Wilcoxon signed rank test indicated lower post‐test ranks compared to pre‐test ranks (depression Z −1.34, p = 0.18; anxiety Z −1.45, p = 0.15).

Conclusions

Mental health problems are prevalent in patients who receive anti‐VEGF treatment. Healthcare providers should recognise these problems and related factors in order to refer patients to appropriate care in a timely manner. Outcomes on the usability and feasibility of E‐PsEYE are promising as a prelude to performing a randomised controlled trial, which will shed more light on its (cost‐)effectiveness.

Low vision rehabilitation in improving the quality of life for patients with impaired vision: A systematic review and meta-analysis of 52 randomized clinical trials

BACKGROUND AIM

Low vision rehabilitation optimizes the use of residual vision after severe vision loss, but also teaches skills to improve visual functioning in daily life. These skills promote independence and active participation in society. This meta-analysis was designed to evaluate the efficacy of low vision rehabilitation in improving the quality of life (QoL) in visually impaired adults.

METHODS

We searched the Cochrane Library, PubMed, EMBASE, and Web of Science up to January 1, 2020. Randomized controlled trials (RCTs) that compared rehabilitation interventions with active or inactive controls were included. The standardized mean difference (SMD) with a 95% confidence interval (CI) was estimated to compare outcomes. Two reviewers extracted data and assessed trial quality independently. All statistical analyses were performed using the standard statistical procedures of RevMan 5.2.

RESULTS

A total of 52 RCTs with 6,239 participants were included in this meta-analysis. Compared to inactive comparators including waiting list or no care, low vision rehabilitation improved vision-related QoL, visual functioning (QoL: psychological aspect), and self-efficacy or self-esteem (QoL: psychological aspect), with pooled SMDs of -0.61 (95% CI -0.95 to -0.26; P = .0006), -1.14 (95% CI -1.69 to -0.59; P < .0001), and -0.84 (95% CI -1.47 to -0.22; P < .0001), respectively. Compared to active comparators, low vision rehabilitation improved vision-related QoL (SMD -0.26; 95% CI -0.46 to -0.06; P = .01) and activities of daily living (QoL: physical aspect) (SMD -0.39; 95% CI -0.67 to -0.12 P < .0001). However, no significant difference in health-related QoL and adaptation to vision loss (QoL: psychological aspect) was found between low vision rehabilitation and inactive comparators.

CONCLUSIONS

This meta-analysis indicated that low vision rehabilitation interventions, particularly psychological therapies and methods of enhancing vision, may improve vision-related QoL and visual functioning in people with sight loss compared to usual care. Further studies should explore longer maintenance effects and the costs of several types of low vision rehabilitation. Studies characterizing the mechanisms of rehabilitation interventions in different settings, including low-income countries, are also required.

The Prevalence and Determinant Factors of Self-Reported Depressive Symptoms Among Elderly People with Visual Impairment Attending an Outpatient Clinic in Ethiopia

BACKGROUND

Depression among older adults with visual impairment is the commonest psychiatric problem and causes a range of effects in on disability and progression of visual health outcomes that may even end in death. In Ethiopia, there are gaps in the detection of the comorbidity of mental health problems especially depressive symptoms among those older people. This study aimed to assess the prevalence of self-reported depressive symptoms and determinant factors among the elderly people with visual impairment attending the ophthalmologic outpatient clinic.

METHODS

A group of 423 elderly people with visual impairment invited by systematic random sampling technique to took part in the interview for this cross-sectional study at Menelik II referral hospital, Addis Ababa, Ethiopia from January to June 2019. Descriptive statistics like frequency, percentage, mean and standard deviation were used to summarize the distribution of the data. Binary logistic regression analysis was employed to examine the associated factors. An adjusted odds ratio with a 95% confidence interval was used for reporting the result, and a p-value of <0.05 was considered as statistically significant.

RESULTS

The prevalence of self-reported depressive symptoms among elderly people with visual impairment was 26.7% with a 95% confidence interval (22.6-30.8). Widowhood, single and/divorced [Adjusted Odds Ratio (AOR)= 3.17, 95% CI: 1.71, 5.91]; [AOR=2.70, 95% CI: 1.35, 5.38], respectively, poor social support [AOR=4.34, 95% CI: 1.84, 10.24], severe level [AOR=2.63, 95% CI: 1.73, 6.63] and longer duration (>5 years) of the illness [AOR=3.15, 95% CI: 1.60, 6.19] were the factors significantly associated with higher odds of depressive symptoms.

CONCLUSION

The Prevalence of self-reported depressive symptoms among elderly people with visual impairment in Ethiopia was high. Public health interventions targeting risky individuals with high depressive symptoms are needed to reduce depressive symptoms and to prevent disability and poor medical illnesses outcomes related to depressive symptoms.

Training results in increased practitioner confidence and identification of depression in people with low vision: a mixed methods study

PURPOSE

The prevalence of depression in people with low vision is high and often goes undiagnosed. There is the potential for those who provide low vision services to perform concurrent depression screening. However, prior training in depression identification and suitable referral pathways is required. The aims of this study were: (1) to assess the impact of a training programme on practitioners' confidence and behaviour in addressing depression in patients with low vision, and (2) to review the training programme and identify areas for further development.

METHODS

A convergent mixed methods approach was used. Questionnaires were completed by practitioners pre-, immediately post- and 6 months post- training (n = 40) to assess practitioner confidence in approaching depression in patients with low vision. Qualitative interviews were performed with a subset of practitioners 6 months post-training (n = 9). Additionally, routine data from the Low Vision Service Wales (LVSW) database was used to determine the change in the number of practitioners identifying depression in patients, and the change in the number of patients identified at risk of depression 6 months post-training.

RESULTS

Of the 148 practitioners who completed low vision assessments pre- and post-training, 28 (18.9%) documented risk of depression in their patients pre-training, which increased substantially to 65 (43.9%) post-training (p < 0.0001). Mixed methods analysis confirmed increased documentation of depressive symptoms by practitioners. Practitioner confidence increased following training, with 92.3% feeling more confident to approach emotional issues with patients and 92.2% intending to use the recommended screening tool to identify depression. Interviews provided insight into areas where confidence was still lacking. Quantitative questionnaires revealed that training content was considered appropriate by 91% of participants. Interviews confirmed these findings while expanding upon possibilities for programme improvement.

CONCLUSIONS

Training for depression screening was found to be time-efficient and acceptable for LVSW practitioners and shown to increase practitioner confidence in the identification of depression. Additionally, the programme changed behaviour, resulting in an increase in the identification of depression in patients with low vision. However, this is a complex topic and ongoing development is required to embed depression screening as an integral part of low vision services.

Psychological complexities of visual restoration

In this paper, we report the psychological and emotional experience of a patient who regained vision after over a decade of vision loss. The negative psychological implications of blindness are well recognised and there is a robust link between visual impairment and low mood and depressive symptoms. Although uncommon, low mood and depressive symptoms have been reported in patients whose sight has been restored, and lack of research gives rise to the possibility their prevalence may be grossly under-recognised in such patient groups. The effects can be so severe that patients may revert to living in darkness in mimicry of their previous lifestyle, effectively obviating the sight-restoring surgery. Healthcare professionals have a responsibility to address this traditionally neglected need by facilitating social, psychological and medical interventions that may ease the return to vision.

Self-reported vision impairment, vision correction, and depressive symptoms among middle-aged and older Chinese: Findings from the China health and retirement longitudinal study

OBJECTIVE

To investigate associations between vision impairment (VI), vision correction (VC) and depressive symptoms among middle-aged and older Chinese.

METHODS

22 203 participants aged ≥45 years from China Health and Retirement Longitudinal Study 2011 to 2015 were divided into four self-reported VI categories: no VI, distance VI (DVI) only, near VI (NVI) only, and both distance and near VI (DNVI); and four self-reported VI/VC subgroups: VI(+)/VC(-), VI(+)/VC(+), VI(-)/VC(-) and VI(-)/VC(+). Depressive symptoms were evaluated by 10-item Center for Epidemiological Studies Depression Scale (CESD-10).

RESULTS

Compared with no VI, DVI only (OR = 2.12, 95% CI: 1.95, 2.31), NVI only (OR = 1.51, 95% CI: 1.39, 1.63) and DNVI (OR = 2.75, 95% CI: 2.47, 3.07) were associated with higher odds of depressive symptoms. Compared with VI(+)/VC(-), VI(+)/VC(+) (OR = 0.91, 95% CI: 0.83, 0.98), VI (-)/VC(-) (OR = 0.50, 95% CI: 0.48, 0.53) and VI(-)/VC(+) (OR = 0.49, 95% CI: 0.47, 0.54) were associated with lower odds of depressive symptoms. Compared with no VI at baseline, baseline DNVI was significantly associated with higher odds of depressive symptoms after two (OR = 1.48, 95% CI: 1.16, 1.88) and four (OR = 1.32, 95% CI: 1.04, 1.68) years. Baseline depressive symptoms were significantly associated with higher odds of VI after two (OR = 1.53, 95% CI: 1.34, 1.74) and four (OR = 1.54, 95% CI: 1.34, 1.76) years.

CONCLUSION

Adults with DNVI were more likely to report depressive symptoms in the future and those with depressive symptoms were more likely to report VI in the future. VC might be a protective factor for preventing depressive symptoms among adults with VI.

Cognitive impairment negatively impacts allied health service uptake: Investigating the association between health and service use

There is widespread concern about the potential impact on health and social care services of the ageing population and long-term health conditions, such as dementia. To effectively plan services it is important to understand current need and use and identify gaps in provision. Using data from the Cognitive Function and Ageing Study Wales (CFAS Wales), we used logistic regression to model the relationship between health (self-rated health, cognitive impairment, and activities of daily living), and the use of health and care services. CFAS Wales is a longitudinal cohort study of people aged 65 years and over, in two areas in Wales, UK, over-sampling those aged 75 years and over. Participants (n = 3593) answered a wide range of health and lifestyle questions and completed a variety of cognitive and physical health assessments. Data from 3153 people from wave 1 and 1968 people from wave 2 were analysed. As anticipated we found poorer health, on some indicators, predicted greater service use, including social care, hospital, general practitioner, and nursing services. However, cognitive impairment did not predict greater service use, except for social care. Controlling for age, sex, socio-economic status, social connection indices and area environment, conversely we found lower reported uptake of allied health services by people with cognitive impairment. Further analysis showed that people with a cognitive impairment were less likely to report having a sight-check or seeing a dentist in the previous year, a finding replicated in wave 2. These differences were not explained by transportation issues. In contrast, we did not find a significant difference in reported uptake of hearing checks or physiotherapist use, with mixed evidence of differences in chiropodist visits. Not accessing these preventative services may not only exacerbate existing conditions but have further downstream negative consequences for health and well-being in people who are cognitively impaired.

Visual Impairment and Mental Health: Unmet Needs and Treatment Options

Purpose

An estimated 2.2 billion people are visually impaired worldwide. Given that age-related vision loss is a primary cause of vision impairment, this number is projected to rise with increases in average lifespan. Vision loss often results in significant disability and is associated with a substantial economic burden, reduced quality-of-life, concurrent medical issues, and mental health problems. In this review, the mental health needs of people with vision impairment are examined.

Patients and methods

A review of recent literature on mental health outcomes and current treatments in people with visual impairment was conducted.

Results

Considerable data indicate that rates of depression and anxiety are elevated among people with visual impairments. Moreover, individuals of lower socioeconomic status may be at increased risk for vision impairment and subsequent mental health problems. Existing psychosocial interventions for improving mental health in people with visual impairment show some promise, but are limited by low adherence and lack generalizability.

Conclusion

In order to improve outcomes, a better understanding of the mechanisms linking visual impairment and poor mental health is needed. It will also be essential to develop more effective interventions and expand access to services to improve the detection and treatment of mental health problems in this population.

Mastery and self-esteem mediate the association between visual acuity and mental health: a population-based longitudinal cohort study

BACKGROUND

With deteriorating eyesight, people often become dependent on others for many aspects of their daily lives. As a result, they feel less 'in control' and experience lower self-esteem. Lower sense of mastery and self-esteem are known to predict depression, but their roles in people with visual impairment have only marginally been investigated. Therefore, this study aimed to determine the influence of mastery and self-esteem on the relationship between visual acuity and mental health.

METHODS

A longitudinal cohort study was performed using data from the Longitudinal Aging Study Amsterdam (LASA), collected between 2001 and 2012. A community-based population of 2599 older adults were included, who were randomly selected from population registers. Outcomes of interest were the Pearlin Mastery Scale, Rosenberg Self-Esteem Scale, Center for Epidemiologic Studies - Depression scale and the Hospital Anxiety Depression Scale - Anxiety subscale. Linear mixed models were used to establish the association between visual acuity and mental health over time.

RESULTS

Mean age was 72 years, 56% was female and 1.2% qualified as having low vision. Visual impairment was associated with a lower sense of mastery (β = - 0.477, p < 0.001), lower self-esteem (β = - 0.166, p = 0.008) and more depression (β = 0.235, p < 0.001). No significant association between visual acuity and anxiety was found. The relationship between visual acuity and depression was mediated by self-esteem (25%) and sense of mastery (79%).

CONCLUSIONS

Vision loss was associated with depression. This association was mediated by self-esteem and sense of mastery. This provides us with new possibilities to identify, support and treat those at risk for developing depression by aiming to increase their self-esteem and sense of mastery.

Activation in individuals with vision loss

Vision loss and blindness are significant causes of disability. Patient activation has been previously unstudied in individuals with vision loss. Among our 146 participants, visual acuities for 38.3 percent were better than 20/70, 43.2 percent had acuities between 20/70 and 20/400, and 12.3 percent had acuities of <20/400. Participants with lower Patient Activation Measure scores missed more clinic visits (p = 0.017); those participants with caregivers also had lower PAM scores (p = 0.002). Targeting interventions to address patient activation in patients with vision loss may increase patient involvement in their care, increase treatment protocol adherence, and improve outcomes.

Pars plana vitrectomy relieves the depression in patients with symptomatic vitreous floaters

AIM

To investigate the depressive state among the patients with symptomatic vitreous floaters (SVF), as well as its change after SVF removal via vitrectomy surgery.

METHODS

Twenty-eight eyes of 28 patients who underwent 27-gauge pars plana vitrectomy (PPV) for SVF were included. Thirty-nine eyes of 39 age- and gender-matched healthy volunteers without SVF were also recruited as a healthy control. Center for Epidemiologic Studies Depression (CES-D) was used to assess volunteers and patients' depression (before and 1wk after PPV).

RESULTS

The CES-D score was 18.3±8.6 for patients, and was 12.4±6.0 for healthy control (P=0.003). Patients were significantly more likely to be in a depressive state (53.6%, defined as CES-D score ≥16) than the healthy control (20.5%, P=0.005). For patients with SVF, the CES-D score was negatively correlated with their age (r _s=-0.42, P=0.025). After PPV, both the CES-D score (11.9±5.4 vs 18.3±8.6, P<0.001) and proportion of depressive state (18.5% vs 53.6%, P=0.005) were significantly decreased.

CONCLUSION

This study suggests that symptoms of vitreous floaters have an apparently negative impact on patients' psychological state. The PPV can effectively relieve the depressive state for patients with SVF.

Low vision rehabilitation for better quality of life in visually impaired adults

BACKGROUND

Low vision rehabilitation aims to optimise the use of residual vision after severe vision loss, but also aims to teach skills in order to improve visual functioning in daily life. Other aims include helping people to adapt to permanent vision loss and improving psychosocial functioning. These skills promote independence and active participation in society. Low vision rehabilitation should ultimately improve quality of life (QOL) for people who have visual impairment.

OBJECTIVES

To assess the effectiveness of low vision rehabilitation interventions on health-related QOL (HRQOL), vision-related QOL (VRQOL) or visual functioning and other closely related patient-reported outcomes in visually impaired adults.

SEARCH METHODS

We searched relevant electronic databases and trials registers up to 18 September 2019.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) investigating HRQOL, VRQOL and related outcomes of adults, with an irreversible visual impairment (World Health Organization criteria). We included studies that compared rehabilitation interventions with active or inactive control.

DATA COLLECTION AND ANALYSIS

We used standard methods expected by Cochrane. We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included 44 studies (73 reports) conducted in North America, Australia, Europe and Asia. Considering the clinical diversity of low vision rehabilitation interventions, the studies were categorised into four groups of related intervention types (and by comparator): (1) psychological therapies and/or group programmes, (2) methods of enhancing vision, (3) multidisciplinary rehabilitation programmes, (4) other programmes. Comparators were no care or waiting list as an inactive control group, usual care or other active control group. Participants included in the reported studies were mainly older adults with visual impairment or blindness, often as a result of age-related macular degeneration (AMD). Study settings were often hospitals or low vision rehabilitation services. Effects were measured at the short-term (six months or less) in most studies. Not all studies reported on funding, but those who did were supported by public or non-profit funders (N = 31), except for two studies. Compared to inactive comparators, we found very low-certainty evidence of no beneficial effects on HRQOL that was imprecisely estimated for psychological therapies and/or group programmes (SMD 0.26, 95% CI -0.28 to 0.80; participants = 183; studies = 1) and an imprecise estimate suggesting little or no effect of multidisciplinary rehabilitation programmes (SMD -0.08, 95% CI -0.37 to 0.21; participants = 183; studies = 2; I2 = 0%); no data were available for methods of enhancing vision or other programmes. Regarding VRQOL, we found low- or very low-certainty evidence of imprecisely estimated benefit with psychological therapies and/or group programmes (SMD -0.23, 95% CI -0.53 to 0.08; studies = 2; I2 = 24%) and methods of enhancing vision (SMD -0.19, 95% CI -0.54 to 0.15; participants = 262; studies = 5; I2 = 34%). Two studies using multidisciplinary rehabilitation programmes showed beneficial but inconsistent results, of which one study, which was at low risk of bias and used intensive rehabilitation, recorded a very large and significant effect (SMD: -1.64, 95% CI -2.05 to -1.24), and the other a small and uncertain effect (SMD -0.42, 95%: -0.90 to 0.07). Compared to active comparators, we found very low-certainty evidence of small or no beneficial effects on HRQOL that were imprecisely estimated with psychological therapies and/or group programmes including no difference (SMD -0.09, 95% CI -0.39 to 0.20; participants = 600; studies = 4; I2 = 67%). We also found very low-certainty evidence of small or no beneficial effects with methods of enhancing vision, that were imprecisely estimated (SMD -0.09, 95% CI -0.28 to 0.09; participants = 443; studies = 2; I2 = 0%) and multidisciplinary rehabilitation programmes (SMD -0.10, 95% CI -0.31 to 0.12; participants = 375; studies = 2; I2 = 0%). Concerning VRQOL, low-certainty evidence of small or no beneficial effects that were imprecisely estimated, was found with psychological therapies and/or group programmes (SMD -0.11, 95% CI -0.24 to 0.01; participants = 1245; studies = 7; I2 = 19%) and moderate-certainty evidence of small effects with methods of enhancing vision (SMD -0.24, 95% CI -0.40 to -0.08; participants = 660; studies = 7; I2 = 16%). No additional benefit was found with multidisciplinary rehabilitation programmes (SMD 0.01, 95% CI -0.18 to 0.20; participants = 464; studies = 3; I2 = 0%; low-certainty evidence). Among secondary outcomes, very low-certainty evidence of a significant and large, but imprecisely estimated benefit on self-efficacy or self-esteem was found for psychological therapies and/or group programmes versus waiting list or no care (SMD -0.85, 95% CI -1.48 to -0.22; participants = 456; studies = 5; I2 = 91%). In addition, very low-certainty evidence of a significant and large estimated benefit on depression was found for psychological therapies and/or group programmes versus waiting list or no care (SMD -1.23, 95% CI -2.18 to -0.28; participants = 456; studies = 5; I2 = 94%), and moderate-certainty evidence of a small benefit versus usual care (SMD -0.14, 95% CI -0.25 to -0.04; participants = 1334; studies = 9; I2 = 0%). ln the few studies in which (serious) adverse events were reported, these seemed unrelated to low vision rehabilitation.

AUTHORS' CONCLUSIONS

In this Cochrane Review, no evidence of benefit was found of diverse types of low vision rehabilitation interventions on HRQOL. We found low- and moderate-certainty evidence, respectively, of a small benefit on VRQOL in studies comparing psychological therapies or methods for enhancing vision with active comparators. The type of rehabilitation varied among studies, even within intervention groups, but benefits were detected even if compared to active control groups. Studies were conducted on adults with visual impairment mainly of older age, living in high-income countries and often having AMD. Most of the included studies on low vision rehabilitation had a short follow-up, Despite these limitations, the consistent direction of the effects in this review towards benefit justifies further research activities of better methodological quality including longer maintenance effects and costs of several types of low vision rehabilitation. Research on the working mechanisms of components of rehabilitation interventions in different settings, including low-income countries, is also needed.

Perceptual learning in patients with Stargardt disease

OBJECTIVE

To evaluate the efficacy of Perceptual Learning in improving the peripheral reading performance of patients with Stargardt disease (STGD).

DESIGN

Prospective observational randomized study.

PARTICIPANTS

Fourteen consecutive patients (7 females, 7 males; median age of 50.4 ± 12.8 years) with STGD were analyzed and divided into two groups: Group A received "Win-flash" as Perceptual Learning training and Group B was used as control.

METHODS

Subjects underwent an ophthalmic evaluation at baseline, after perceptual learning training and at 6 months of follow-up. Outcomes measured included reading speed, contrast sensitivity and fixation stability.

RESULTS

Reading speed improved of 51,7% after training in group A. Visual acuity, contrast sensitivity and fixation stability enhanced in group A after training from 0.89 (±0.09) LogMAR to 0.75 (±0.2) LogMAR (t(6)= 3.6, p= 0.001), from 0.8 (±0.3) LogC (0.6 - 0.9) to 1.3 (±0.3) LogC (t(13)=3.17, p= 0.003) and from 59.3 % (± 24.3) to 71.5 % (± 20.4) (t(13)=1.8 p= 0.04), respectively. No changes were found in group B. At 6-monts of follow-up, visual acuity and contrast sensitivity decreased in group A.

CONCLUSIONS

STGD patients receiving "Win-flash training", as PL technique, showed an improvement of reading performance on a real-world task. Early follow-up for perceptual learning re-intervention should be considered.

Depressive symptoms in people with vision impairment: a cross-sectional study to identify who is most at risk

OBJECTIVE

To identify the risk factors for significant depressive symptoms in people with visual impairment in England and Wales to provide information on who is most at risk and to whom support services could be targeted in future.

DESIGN

A cross-sectional study using baseline data from a pragmatic randomised controlled trial.

SETTING AND PARTICIPANTS

990 participants aged 18 or over attending 1 of 14 low-vision rehabilitation primary care optometry-based clinics in South Wales or two hospital clinics in London.

OUTCOME MEASURE

A score of ≥6 on the Geriatric Depression Scale-15 was classed as clinically significant depressive symptoms.

RESULTS

In a multivariable logistic regression model, significant depressive symptoms were associated with age (adjusted OR (AOR)=0.82, 95% CI: 0.66 to 0.90, p<0.001), ethnicity (AOR non-white compared with white=1.72, 95% CI: 1.05 to 2.81, p=0.031), total number of eye conditions (AOR for two vs one condition=0.98, 95% CI: 0.67 to 1.43; three or more vs one condition=0.34, 95% CI: 0.15 to 0.75, p=0.026), self-reported health (AOR for excellent vs poor=0.01, 95% CI: 0.00 to 0.12; very good vs poor=0.06, 95% CI: 0.03 to 0.13; good vs poor=0.14, 95% CI: 0.08 to 0.24; fair vs poor=0.28, 95% CI: 0.18 to 0.46, p<0.001) and self-reported visual functioning (AOR=1.45, 95% CI: 1.31 to 1.61, p<0.001).

CONCLUSION

Younger age, a non-white ethnicity, fewer eye conditions and poorer self-reported health and visual function are risk factors for significant depressive symptoms in this population.

The association of vision loss and dimensions of depression over 12 years in older adults: Findings from the Three City study

BACKGROUND

The established relationship between vision impairment and depression is limited by the examination of depression only as a unidimensional construct. The present study explores the vision-depression relationship using a dimensional approach.

METHODS

9036 participants aged 65 years and above enrolled in the Three-City study were included. Relationships between baseline near Vision Impairment (VI) or self-reported distance Visual Function (VF) loss with trajectory of four dimensions of depression - depressed affect, positive affect, somatic symptoms and interpersonal problems - over 12 years were examined using mixed-effects models. Depression dimensions were determined using the four-factor structure of the Centre for Epidemiology Studies-Depression Scale (CESD).

RESULTS

In the fully adjustment models, mild near VI predicted poorer depressed affect (b = 0.04, p = .002) and positive affect (b = -0.06, p < 0.001) over time, with evidence of longer term adjustment. Distance VF loss was associated with poorer depressed affect (b = 0.27, p ≤ .001), positive affect (b = -0.15, p = .002), and somatic symptoms (b = 0.18, p ≤ .001) at baseline, although only the association with depressed affect was significant longitudinally (b = 0.01, p = .001). Neither near VI nor distance VF loss was associated with interpersonal problems.

LIMITATIONS

This paper uses a well-supported model of depression dimensions, however, there remains no definite depression dimension model. Distance VF loss was self-reported, which can be influenced by depression symptoms.

CONCLUSIONS

Vision impairment in older adults is primarily associated with affective dimensions of depression. A reduction in social connectedness and ability to engage in pleasurable activities may underlie the depression-vision relationship. Older adults with vision impairment may benefit from targeted treatment of affective symptoms, and pleasant event scheduling.

Association between depressive syndrome and visual complaints among elderly caregivers

ABSTRACT Objectives To determine depressive syndrome in community-dwelling elderly caregivers; and to test the association between such syndrome and both visual complaints (VC) and aspects of care. Methods This is a cross-sectional study conducted with 332 elderly caregivers. Geriatric Depression Scale (GDS-15) was used to screen for depressive symptoms (cutoff > 5 points). Logistic regression was performed to identify associations between depression and both VC and aspects related to care. Results Median age of the caregivers was 68 years. The majority was female (75.9%) and took care of a spouse (84.3%). The prevalence of depressive syndrome was 22.6%. The syndrome was associated with VC when it affected activities of daily living (OR = 2.4; 95% CI: 1.37-4.27) and caring for an individual with cognitive impairment (OR = 1.85; 95% CI: 1.05-3.26). Conclusions While measured aspects of care did not exert an influence on the incidence of depressive symptoms, VC associated to functional limitation and caring for elderly individuals with cognitive impairment was associated with such symptoms in the elderly caregivers.

Incidence and causes of visual impairment in Japan: the first nation-wide complete enumeration survey of newly certified visually impaired individuals

PURPOSE

To investigate the visual impairment certification status in Japan.

STUDY DESIGN

Observational cross-sectional study.

METHODS

We asked all welfare offices throughout Japan to submit data concerning age, sex, causative diseases, and visual impairment grades for newly certified visually impaired individuals aged ≥ 18 years in the fiscal year of 2015. The certification was based on criteria of the Act on Welfare of Physically Disabled Persons.

RESULTS

In total, data were collected for 12,505 newly certified visually impaired individuals. The most common age group for these individuals was 80-89 years (29.6%), followed by 70-79 (26.3%) and 60-69 (17.3%) years. The most common causative disease was glaucoma (28.6%), followed by retinitis pigmentosa (14.0%), diabetic retinopathy (12.8%), and macular degeneration (8.0%). Glaucoma was the most common causative disease in both sexes (30.2% in men and 27.0% in women). The most common impairment grade was grade 2 (31.8%), followed by grades 5 (24.3%) and grade 1 (16.1%). The number of visually impaired individuals with underlying glaucoma had increased in comparison with the number in the most recent surveys (from fiscal years 2007 to 2009), whereas the number of individuals with underlying diabetic retinopathy and macular degeneration had decreased.

CONCLUSION

To our knowledge, this is the first nation-wide complete enumeration survey of newly certified visually impaired individuals in Japan. These findings may contribute to administrative activities concerning medical welfare as well as educational activities for preventing visual impairment.

The mediating roles of functional limitations and social support on the relationship between vision impairment and depressive symptoms in older adults

Vision impairment is prevalent and it is strongly associated with depressive symptoms in older adults. This study aimed to investigate the mediating roles of functional limitations and social support on the relationship between vision impairment and depressive symptoms in older adults. This study used data from a probability-based sample of 1,093 adults aged 60 and older in Shanghai, China. Structural equation models were used to examine the structural relationships among sets of variables simultaneously, including vision impairment, activities of daily living ADLs, instrumental ADLs (IADLs), friends support, family support, relatives support and depressive symptoms. The bootstrapping method and the program PRODCLIN were used to test the indirect effects of these variables. This study found that vision impairment was directly associated with a higher level of depressive symptoms, and the association was partially mediated by functional limitations (IADLs) and social support (friends support). The study demonstrates that improving social support from friends and enhancing social participation for visually impaired older adults can reduce depressive symptoms. More importantly, this study contributes to the knowledge of mediating mechanisms between vision impairment and depressive symptoms.

WRINKLED VASCULARIZED RETINAL PIGMENT EPITHELIUM DETACHMENT PROGNOSIS AFTER INTRAVITREAL ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY

BACKGROUND/PURPOSE

Neovascular age-related macular degeneration (nAMD) is frequently associated with vascularized pigment epithelial detachment (v-PED). We observed a peculiar characteristic of v-PED characterized by small lacy folds of the retinal pigment epithelium, appearing as a wrinkled PED (w-PED) on spectral domain optical coherence tomography (SD-OCT). Our purpose was to describe the visual prognosis and number of intravitreal injections in w-PED compared with non-w-PED.

METHODS

In this retrospective, case-control series, we reviewed retrospectively medical records of 52 eyes of 51 patients who were consecutively included between November 1 and 30, 2015 with a previous minimum 3-year follow-up. Inclusion criteria were: neovascular age-related macular degeneration, affected with w-PED. Baseline characteristics, best-corrected visual acuity (BVCA), number of intravitreal anti-vascular endothelial growth factor injections (anti-VEGF IVT) and maximal recurrence-free interval, that is, without intravitreal anti-vascular endothelial growth factor injection, were analyzed. A w-PED was defined as a v-PED ≥200 μm in height on SD-OCT imaging, presenting with at least 4 small lacy folds on the surface of the retinal pigment epithelium. Patients were compared with a control group, that is, patients harboring PED without wrinkle shape (non-w-PED). All patients had been treated by intravitreal anti-vascular endothelial growth factor injection of either ranibizumab (IVR) or aflibercept (IVA) using a pro re nata (PRN) protocol after three initial monthly treatments, with a minimum of follow-up of 3 years.

RESULTS

Two groups of patients were compared, w-PED (29 eyes, from 29 patients), and non-w-PED (23 eyes from 22 patients). In the w-PED group, mean BCVA evolved from 0.28 (±0.18) log MAR (20/40, range 20/25-20/63) at baseline, to 0.29 (±0.21) log MAR (20/40, range 20/25-20/63) at 1 year (P = 0.41), 0.34 (±0.26) log MAR (20/40, range 20/25-20/80) at 2 years (P = 0.49), 0.35 (±0.28) log MAR (20/40, range 20/25-20/80) at 3 years (P = 0.54). In the non-w-PED group, mean BCVA was 0.40 (±0.28) log MAR (20/50, range 20/25-20/100) at baseline and decreased to 0.48 (±0.46) log MAR (20/63, range 20/20-20/160) at 1 year (P = 0.19), 0.48 (±0.35) log MAR (20/63, range 20/25-20/125) at 2 years (P = 0.02), 0.60 (±0.38) log MAR (20/80, range 20/32-20/200) at 3 years (P = 0.002). In the w-PED group, the mean maximal documented recurrence-free interval was 7.87 (±2.94) months at Year 1, 13.5 (±7.52) at Year 2 and 14.78 (±10.70) at Year 3, versus 4.59 (±2.95) months at Year 1, 7.83 (±6.62) at Year 2, 8.57 (±11.18) at Year 3 in the non-w-PED group (P = 0.0004; 0.0101; 0.0168 respectively at Years 1, 2 and 3).

DISCUSSION

The evolution of v-PED after intravitreal anti-vascular endothelial growth factor injection is still difficult to predict despite intense clinical research in this topic. In our study, we noticed that w-PED might be a phenotypic prognosis factor for better visual acuity and longer maximal recurrence-free interval.

Mental stress as consequence and cause of vision loss: the dawn of psychosomatic ophthalmology for preventive and personalized medicine

The loss of vision after damage to the retina, optic nerve, or brain has often grave consequences in everyday life such as problems with recognizing faces, reading, or mobility. Because vision loss is considered to be irreversible and often progressive, patients experience continuous mental stress due to worries, anxiety, or fear with secondary consequences such as depression and social isolation. While prolonged mental stress is clearly a consequence of vision loss, it may also aggravate the situation. In fact, continuous stress and elevated cortisol levels negatively impact the eye and brain due to autonomous nervous system (sympathetic) imbalance and vascular dysregulation; hence stress may also be one of the major causes of visual system diseases such as glaucoma and optic neuropathy. Although stress is a known risk factor, its causal role in the development or progression of certain visual system disorders is not widely appreciated. This review of the literature discusses the relationship of stress and ophthalmological diseases. We conclude that stress is both consequence and cause of vision loss. This creates a vicious cycle of a downward spiral, in which initial vision loss creates stress which further accelerates vision loss, creating even more stress and so forth. This new psychosomatic perspective has several implications for clinical practice. Firstly, stress reduction and relaxation techniques (e.g., meditation, autogenic training, stress management training, and psychotherapy to learn to cope) should be recommended not only as complementary to traditional treatments of vision loss but possibly as preventive means to reduce progression of vision loss. Secondly, doctors should try their best to inculcate positivity and optimism in their patients while giving them the information the patients are entitled to, especially regarding the important value of stress reduction. In this way, the vicious cycle could be interrupted. More clinical studies are now needed to confirm the causal role of stress in different low vision diseases to evaluate the efficacy of different anti-stress therapies for preventing progression and improving vision recovery and restoration in randomized trials as a foundation of psychosomatic ophthalmology.

Psychological Aspects and Depression in Patients with Symptomatic Keratoconus

Purpose

To assess the psychological status of keratoconus sufferers and to determine the relationship between depression and visual impairment in this group of patients.

Methods

Fifty-six patients with keratoconus and forty-seven age- and gender-matched healthy control subjects were retroprospectively analyzed. Every participant underwent a complete ophthalmological examination. Keratoconus diagnosis was confirmed with corneal topography and tomography. Zung Depression Inventory Questionnaire and Patient Health Questionnaire-9 (PHQ-9) were completed by everyone.

Results

Visual acuity (logMAR 0.53 ±0.30 versus 0.11 ± 0.16), PHQ-9 score (10.20 ± 4.00 versus 5.40 ± 5.01), and Zung score (46.52 ± 8.70 versus 38.53 ± 8.41) showed a statistically significant difference between keratoconus patients and healthy controls (p < 0.001 for all). Worse visual acuity was strongly correlated with older individuals (rho = 0.339, p=0.011) and higher PHQ-9 (rho = 0.765, p < 0.001) and Zung score (rho = 0.672, p < 0.001).

Conclusion

Depressive disorders appear to be directly associated with keratoconus, both in frequency and intensity. Worse visual acuity and older age could be identified as predictive factors for their emotional status. Moreover, the disease itself could be recognized as an independent risk factor for depression development, underlying the need for close monitoring and supportive management. To the best of our knowledge, our study is the first in the literature to elaborate the association between keratoconus and depression, by assessing two different questionnaires simultaneously.

Quantitative analyses of factors related to anxiety and depression in patients with retinitis pigmentosa

The purpose of this study is to determine the factors related to anxiety and depression in patients with retinitis pigmentosa (RP). The status of anxiety and depression was determined in RP patients with the Hospital Anxiety and Depression Scale (HADS) questionnaire which consisted of subscales for HADS-anxiety (HADS-A) and HADS-depression (HADS-D). The vision-specific quality of life (VSQOL) was assessed with the National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ25). The correlations between the HADS-A or HADS-D scores and vision-related clinical parameters such as the best-corrected visual acuity (BCVA), Functional Acuity Score, Functional Field Score, Functional Vision Score, the NEI- VFQ25 subscale score were determined. The socioeconomic status, such as the work status and membership in the RP society, was investigated to determine the factors related to the HADS-A and HADS-D scores. One hundred and twelve RP patients (46 men and 66 women) with mean age of 60.7±15.4 (standard deviation) years were studied. The HADS-A score was not significantly correlated with any visual functions but was significantly correlated with the general health condition (r = -0.34, P<0.001) and the role limitation (r = -0.20, P = 0.03) of the NEI-VFQ25 subscale. The HADS-D score was significantly correlated with all the visual functions (r = -0.38 to 0.29, P<0.001), the NEI-VFQ25 subscale score (r = - 0.58 to -0.33, P<0.001) by Spearman’s correlations. The HADS-A score was significantly higher in the members of the RP society than in non-members (P = 0.013). The mean HADS-D score of employed individuals was significantly lower than that of unemployed ones (P = 0.001) by the Mann-Whitney U test. The results indicate that visual function impairments and vision-related quality of life are associated with a depressive state, and the general health condition is related to anxiety in RP patients. Being employed may be strongly correlated with the degree of depression in RP patients.

The relationship between vision impairment and well-being among centenarians: findings from the Georgia Centenarian Study

OBJECTIVE

The current study evaluated the visual function among centenarians and assessed the relationship between vision, social support, and well-being.

METHODS

This study used the data set of the Georgia Centenarian Study including 106 centenarians (18 men and 88 women). We used scores of the Snellen chart for objective vision and self-reports for subjective vision. Social support, depression, and loneliness were also assessed.

RESULTS

Approximately 75% of the centenarians showed some level of objective visual impairment, and 56% of them reported that they had visual impairment. Objective vision impairment was significantly related to depression. Multiple regression analysis revealed that both variables of visual function were significantly associated with depression, but not loneliness. In the model including depression, a significant interaction was obtained for social support and objective vision. Centenarians reported lower level of depression when they had social support. However, centenarians who had low level of visual function tended to report higher depression even if they had social support.

IMPLICATIONS

These results indicated that vision function was related to centenarians' well-being, especially depression. Copyright © 2017 John Wiley & Sons, Ltd.

Visual Impairment Is Associated With Depressive Symptoms-Results From the Nationwide German DEGS1 Study

INTRODUCTION

Visual impairment (VI) is associated with a variety of comorbidities including physical and mental health in industrial countries. Our aim is to examine associations between self-reported impairment and depressive symptoms in the German population.

METHODS

The point prevalence of self-reported VI in Germany was computed using data from the German Health Interview and Examination Survey for adults from 2008 to 2011 (N = 7.783, 50.5% female, age range 18-79 years). VI was surveyed by two questions, one for seeing faces at a distance of 4 m and one for reading newspapers. Depressive symptoms were evaluated with the Patient Health Questionnaire-9 questionnaire and 2-week prevalence was computed with weighted data. Depressive symptoms were defined by a value of ≥10. Logistic regression analysis was performed to analyze an association between self-reported VI and depressive symptoms. Multivariable analysis including adjustment for age, gender, socioeconomic status, and chronic diseases were carried out with weighted data.

RESULTS

The 2-week prevalence of depressive symptoms was 20.8% (95% CI: 16.6-25.7%) for some difficulties in distance vision and 14.4% (95% CI: 7.5-25.9%) for severe difficulties in distance vision, while 17.0% (95% CI: 13.3-21.4%), respectively, 16.7% (95% CI: 10.7-25.1%) for near vision. Analysis revealed that depressive symptoms were associated with self-reported VI for reading, respectively, with low VI for distance vision. Multivariable regression analysis including potential confounders confirmed these findings.

CONCLUSION

Depressive symptoms are a frequent finding in subjects with difficulties in distance and near vision with a prevalence of up to 24%. Depressive comorbidity should therefore be evaluated in subjects reporting VI.

Predictors of depression and life satisfaction in visually impaired people

BACKGROUND

Visual impairment can lead loss of functional ability, necessity of accommodations and assistive technologies or having to rely on others for help. This can bring about feelings of sadness, dependency, inadequacy, and fear, which can put a person at risk for depression and affect one's satisfaction with life.

PURPOSE

The aim of this study was to examine the effects of socio-demographic factors, disability-related factors, optimism, pessimism, self-esteem and social support on depression, and life satisfaction in visually impaired people.

METHODS

A total of 94 visually impaired people completed the measures of socio-demographic and disability-related characteristics, optimism and pessimism, self-esteem, social support, depression and life satisfaction, administered by the authors. Correlational and hierarchical regression analysis was used to examine the relations and test the model for predicting depression and life satisfaction.

RESULTS

The results have shown that depression was negatively related to the level of education, optimism, self-liking, self-competence, support from friends, family and coworkers, and positively related to comorbidity and pessimism. Life satisfaction was positively related to education, socio-economic status, optimism, self-liking, self-competence and support from friends, family and coworkers, and negatively to pessimism. Results have further shown that depression levels were predicted by education, comorbidity, optimism and self-liking, and that self-liking mediated the relationship between optimism and depression. Life satisfaction was predicted by optimism, pessimism, self-liking, friends' support, and depression. Further analysis suggested that the path from optimism to life satisfaction goes through self-liking, friends' support, and depression. Pessimism showed indirect effects through self-liking but also had direct effects on life satisfaction.

CONCLUSIONS

Focusing on optimism, pessimism, self-esteem, and social functioning of visually impaired is important in preventing depression and promoting life satisfaction, and should be a part of rehabilitation practices. Implications for Rehabilitation Screening for depression and mental health problems should be a part of rehabilitation process. Changes in the perception of future outcomes should be monitored and addressed throughout rehabilitation process in order to boost realistic optimism and prevent discouragement and hopelessness. Frequent feedback and positive reinforcement about a persons' progress and ability should be given throughout rehabilitation process in order to promote positive view of oneself and prevent self-esteem problems. Visually impaired people should be encouraged to socialise outside of their families and participate in social activities. This can be integrated in rehabilitation process as a part of everyday homework.
