Spheno-Orbital Meningioma and Vision Impairment-Case Report and Review of the Literature. J Clin Med 2022; 12:jcm12010074. [PMID: 36614875 PMCID: PMC9821601 DOI: 10.3390/jcm12010074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 12/11/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022] Open
Abstract
(1) Background: Spheno-orbital meningioma (SOM) is a very rare subtype of meningioma which arises from the sphenoid ridge with an orbital extension. It exhibits intraosseous tumor growth with hyperostosis and a widespread soft-tissue growth at the dura. The intra-orbital invasion results in painless proptosis and slowly progressing visual impairment. (2) Methods: We present a case of a 46-year-old woman with SOM and compressive optic nerve neuropathy related to it. Her corrected distance visual acuity (CDVA) was decreased to 20/100, she had extensive visual field (VF) scotoma, dyschromatopsia, impaired pattern-reversal visual-evoked potential (PVEP), and decreased thicknesses of the retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC), measured with the swept-source optical coherence tomography (SS-OCT), and a pale optic nerve disc in her left eye. Brain CT and MRI showed a lesion at the base of the anterior cranial fossa, involving the sphenoid wing and orbit. Pterional craniotomy and a partial removal of the tumor at the base of the skull and in the left orbit with the resection of the lesional dura mater and bony defect reconstruction were performed. (3) Results: The histological examination revealed meningothelial meningioma (WHO G1). Decreased CDVA and VF defects completely recovered, and the color vision score and PVEP improved following the surgery, but RNFL and GCC remained impaired. No tumor recurrence was observed at a follow-up of 78 months. (4) Conclusions: Optic nerve dysfunction has the capacity to improve once the compression has been relieved despite the presence of the structural features of optic nerve atrophy.

Amino Acids Metabolism in Retinopathy: From Clinical and Basic Research Perspective. Metabolites 2022; 12:metabo12121244. [PMID: 36557282 PMCID: PMC9781488 DOI: 10.3390/metabo12121244] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 11/22/2022] [Accepted: 12/06/2022] [Indexed: 12/14/2022] Open
Abstract
Retinopathy, including age-related macular degeneration (AMD), diabetic retinopathy (DR), and retinopathy of prematurity (ROP), are the leading cause of blindness among seniors, working-age populations, and children. However, the pathophysiology of retinopathy remains unclear. Accumulating studies demonstrate that amino acid metabolism is associated with retinopathy. This study discusses the characterization of amino acids in DR, AMD, and ROP by metabolomics from clinical and basic research perspectives. The features of amino acids in retinopathy were summarized using a comparative approach based on existing high-throughput metabolomics studies from PubMed. Besides taking up a large proportion, amino acids appear in both human and animal, intraocular and peripheral samples. Among them, some metabolites differ significantly in all three types of retinopathy, including glutamine, glutamate, alanine, and others. Studies on the mechanisms behind retinal cell death caused by glutamate accumulation are on the verge of making some progress. To develop potential therapeutics, it is imperative to understand amino acid-induced retinal functional alterations and the underlying mechanisms. This review delineates the significance of amino acid metabolism in retinopathy and provides possible direction to discover therapeutic targets for retinopathy.

Front Public Health 2022; 10:957586. [PMID: 36466466 PMCID: PMC9714326 DOI: 10.3389/fpubh.2022.957586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 10/28/2022] [Indexed: 11/18/2022] Open
Abstract
Background Visual impairment (VI) is a strong predictor of depression in middle-aged and older adults. However, the underlying mechanisms and pathways have not been well characterized. The purpose of this study was to determine whether Internet use and social participation mediate the effects of self-reported VI on depression. Methods The study used the fourth wave of cross-sectional data from the China Health and Retirement Longitudinal Study, including 19,766 Chinese adults. Depression was assessed according to the CES-D 10 International Scale. Logistic regression models were used to examine the relationship between self-reported VI and depression. While adjusting for relevant covariates, the PROCESS macro (model nos. 6 and 91) was used to assess the chain-mediating effects of Internet use and social participation. Results A total of 17,433 respondents were included in this study. The CES-D 10 results showed that 7,327 middle-aged and older adults had depressive symptoms, of whom 39.5% were male and 10.2% were ≥75 years old. 32.1% of respondents self-reported VI. Regression analysis showed a positive association between VI and depression, while Internet use and social participation had a negative predictive effect on depression. In the mediation analysis, the social participation pathway contributed the most to the total effect, accounting for 52.69% of it. The proportion of Internet use is 37.72%. When these two mediators were considered together in the full model, they accounted for 9.58% of the total effect of VI on depression. Conclusion Internet use and social participation were important mediators that mitigated the effects of VI on depression. Combined with previous evidence, online activities such as e-health and m-health can effectively promote disease monitoring and diagnosis, and various offline social participation activities can also play a role in regulating emotions. Therefore, Internet use and social participation factors may serve as relevant entry points for the development of intervention programs that may further improve the mental health of the visually impaired.

Wang Q, Zhang S, Wang Y, Zhao D, Zhou C. Dual Sensory Impairment as a Predictor of Loneliness and Isolation in Older Adults: National Cohort Study. JMIR Public Health Surveill 2022; 8:e39314. [PMID: 36374533 PMCID: PMC9706378 DOI: 10.2196/39314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 09/28/2022] [Accepted: 10/18/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Loneliness and social isolation are global public health challenges. Sensory impairments (SIs) are highly prevalent among older adults but are often ignored as a part of normal aging. Identifying the role of SIs in loneliness and social isolation could provide insight into strategies for improving public health among older adults. OBJECTIVE This study aims to analyze the effects of SIs on loneliness and social isolation among older adults in rural and urban China. METHODS This cohort study of 3069 older adults (aged 60+) used data from 4 waves (2011, 2013, 2015, and 2018) of the China Health and Retirement Longitudinal Study (CHARLS), a nationally representative survey of adults aged 45 years or older. SIs include hearing impairment (HI), vision impairment (VI), and dual sensory impairment (DSI). DSI is defined as the co-occurrence of VI and HI. Participants with complete data on hearing, vision, social isolation, and loneliness were included in the analysis. Generalized estimating equation models adjusted for covariates were used to examine the relationships of DSI with loneliness and social isolation among older adults. RESULTS Older adults in rural areas have higher prevalence of DSI, loneliness, and social isolation than their urban counterparts. In rural areas, participants with VI only (odds ratio [OR] 1.34, 95% CI 1.12-1.62; P=.002), HI only (OR 1.32, 95% CI 1.02-1.71; P=.03), and DSI (OR 1.84, 95% CI 1.56-2.18; P<.001) were more likely to experience loneliness compared with participants without SIs. DSI showed a statistically significant association with loneliness compared with VI only (OR 1.37, 95% CI 1.22-1.54; P<.001) and HI only (OR 1.39, 95% CI 1.13-1.72; P=.002). In urban areas, participants with VI only (OR 2.44, 95% CI 1.57-3.80; P<.001), HI only (OR 2.47, 95% CI 1.41-4.32; P=.002), and DSI (OR 1.88, 95% CI 1.24-2.85; P=.003) were more likely to experience loneliness compared with participants without SIs. DSI was not associated with the increased likelihood of loneliness compared with HI only or VI only. SIs were not associated with social isolation among older adults in urban and rural areas. Until 2018, 86.97% (2669/3069) reported VI, but only 27.11% (832/3069) and 9.45% (290/3069) were treated with glasses and cataract surgery, respectively; besides, 75 individuals received both glasses and cataract surgery treatment. The prevalence of HI was 74.39% (2283/3069) in 2018, but only 0.72% (22/3069) were treated with a hearing aid. CONCLUSIONS SIs are associated with an increased risk of loneliness rather than social isolation. A compounded risk of DSI on loneliness exists in rural areas rather than in urban areas. These findings expand our knowledge about the effects of SIs on loneliness and social isolation in non-Western populations. Interventions targeting HI only and DSI might be particularly effective for mitigating loneliness of older adults in urban and rural areas, respectively. Considering the high prevalence and low treatment rate of SIs, measures should be taken to make treatment more accessible.

Abstract
This paper reports on how accessibility is being slowly implemented in the current editorial and production workflows of Australian educational publishers. The findings follow from an online questionnaire commissioned by the Australian Publishers Association completed by 65 educational publishers. The paper shows that many publishers have started working on accessibility implementation, but some of them are still at the scoping stage. While many of the participants believe that the quality of “born-accessible” publication is better for all users, they are concerned about the amount of work and financial cost involved. Overall, publishers understand the need for accessibility implementation, but require further practical support and training. Publishers are also interested in working out the best workflows, timing and processes, and most cost-effective way of implementing accessibility.

Abstract
OBJECTIVE This study aims to investigate the relative strength of association between vision impairment (VI) and suicidal ideation, plans, and attempts among adults in the United States. METHOD The study sample consisted of 214,505 adults, aged 18 years and older. Researchers used data from the 2015-2019 National Survey on Drug Use and Health, in which respondents were asked whether they had any suicidal thoughts, plans, and attempts, in the past 12 months. RESULTS Approximately, 4.4% of respondents reported experiencing VI, being blind, or having serious difficulty seeing. Compared to their sighted peers, a relatively high proportion of adults with VI had serious thoughts about suicide (9.0%), suicidal plans (3.0%), or suicidal attempts (1.6%) in the past year. The findings showed that individuals with VI may disproportionately experience suicidal ideation, plans, and attempts, after controlling potentially confounding variables (adjusted odds ratio [AOR] = 1.36; AOR = 1.27; AOR = 1.40, respectively). CONCLUSION With findings demonstrating such a strong association between VI and suicide, this study suggests the importance of screening for suicidal ideation, plans, and attempts among adults with VI, and the strong need for developing behavioral health services which keep this correlation in mind.

Abstract
Vision-impaired (VI) golf is a global para-sport currently played under several different classification systems under different bodies. This study aimed to gather expert opinion to determine whether the current classification systems are fit for the purpose intended and to identify any particular issues where VI impacts the game of golf for the disabled (G4D). A panel of 20 participants with expertise in G4D took part in a three-round Delphi study. The panel agreed that the current classification system(s) for VI golf did not or only partially fulfilled the aim to minimise the impact of VI on the outcome of competition and that there should be one, internationally recognised, classification system. It was agreed that other metrics of VI, in addition to the measurement of visual acuity (VA), need to be considered. Intentional misrepresentation of VI was identified as a cause for concern. The panel agreed that the current classification system does not fully achieve its purpose. Any changes that are made to these classification systems need to be evidence based specific to VI golf. Further research is required to determine how measures of VI affect golfing performance and whether other metrics other than VA are required.

Abstract
Purpose: We systematically retrospected and analyzed the general characteristics of ophthalmic drug clinical trials (CTs) registered in China from January 2014 to December 2021. Methods: Data were retrieved from the Drug Trial Registration and Information Publication Platform and then standardized and statistically classified using bibliometric analysis. Results: We identified 201 drug CTs for eye diseases, including 24 international multicenter trials. The number of drug CTs for eye diseases has considerably increased since 2017 in parallel with new policies to encourage innovation in drugs and medical devices in China. The drug types consist of biologicals (48.26%), chemicals (45.77%), and traditional Chinese medicine/natural medicines (5.97%). The main indications were age-related macular degeneration (AMD; n = 47, 23.38%), macular edema (n = 32, 15.92%), and diabetic retinopathy (n = 19, 9.45%). The trials included those in phase I (n = 67, 33.33%), phase II (n = 33, 16.42%), and phase III (n = 72, 35.82%). The phase I trials comprised 24 innovative drug treatments for AMD and 6 novel drug treatments for neuromyelitis optica spectrum disorders, with 39 biologicals and 27 chemicals. The trials mostly followed a randomized (84.08%) or masked (67.16%) design, with 90.37% of the latter being double-masked trials. Conclusion: Research and development of ophthalmic drugs have substantially increased in recent years and are influenced by regulatory policies. Among these drugs, biologicals for AMD are the most prevalent, followed by biologicals for macular edema. Randomized double-masked research designs are often used and represent high-quality evidence.

Abstract
BACKGROUND Special Olympics International (SOI) has provided eye assessments at no cost to athletes participating in competitions through the Special Olympics Lions Clubs International Foundation Opening Eyes (OE) programme. Access to vision services is crucial given the high rates of eye abnormalities found in studies collected at OE programmes in other countries. As of 2022, no studies covering vision data have been published on SOI athletes specifically from the USA. Therefore, this multiple cross-sectional study hopes to investigate the vision profile of US athletes over three national games, detecting any changes in vision and ocular health outcomes over an 8-year period. METHODS Vision assessments were conducted in the US national games of 2010, 2014 and 2018. Demographic and clinical data from 1427 vision assessments were used in this study. Prevalence of vision and ocular health abnormalities were compared across national games. RESULTS In our cohort of 1427 assessments with athletes' mean age ± SD of 29.8 ± 11.5 years, 85.3% (n = 1170) had an abnormal vision result with at least one of the following findings: decreased visual acuity of 20/40 or worse (31.0%, n = 442), refractive error including myopia (52.8%, n = 754), hypermetropia (15.7%, n = 224), and astigmatism (35.0%, n = 499), ocular misalignment distant (16.2%, n = 224) or near (17.2%, n = 239), or ocular abnormality (19.1%, n = 273). CONCLUSIONS This study demonstrates the burden of vision defects and ocular disease in US SOI athletes over the past decade. While continued effort must be made to train eye providers in caring for patients with ID to increase eyecare accessibility outside of SOI, vision assessments at national games can continue providing opportunities for improved ocular health in children and adults with ID.

Abstract
OBJECTIVE To quantify the burden of vision impairment (VI) and ocular conditions among early late-life women. METHODS Women (n = 254, mean age 66.0 years) participated in a comprehensive vision assessment. Visual acuity (VA) and ocular disorders (diabetic retinopathy, macular degeneration, hypertensive retinopathy, glaucoma and cataracts) were defined clinically. Race, economic strain and education were self-reported. RESULTS The prevalence of presenting VI (VA 20/40 or worse) was 11.0% and 75% of that was correctable (best-corrected VI 2.8%). Black women and those with greater economic strain or less education had a higher prevalence of presenting VI. These disparities were no longer present after considering best-corrected VI. Ocular disease prevalence ranged from 3.3% (age-related macular degeneration) to 30.2% (hypertensive retinopathy), but most participants were unaware of their ocular diagnosis. CONCLUSION The discordance of presenting versus best-corrected VI and lack of knowledge of ocular conditions suggests a need for increased vision services. Access to optimal vision correction may attenuate differences across sociodemographic groups.

Abstract
Purpose To present the eye care seeking behavior among rural adults in South India. Methods This cross-sectional study was conducted between 2019 and 2020 covering three blocks of the Thiruvannamalai district, Tamil Nadu, India. Door-to-door survey was performed to collect demographic information, status of literacy, occupation, and details of previous eye examination. Distance visual acuity was tested for individuals available in the house using a log MAR (logarithm of minimum angle of resonance) chart. Association between demographic details, details of previous eye examination, and status of vision was analyzed using logistic regression. Results A data of 12,913 individuals were included for the analysis, of which 6460 (50.03%) were females. Of the total individuals, 2007 (15.54%) had undergone an eye examination previously. There were 1639 (28.50%) people who had a vision less than 0.2 log MAR in at least one eye. The odds of reported 'previous eye examination' were more among females [odds ratio (OR) 1.48, 95% confidence interval (CI): 1.32-1.66, P < 0.001]; individuals aged above 60 years [OR: 11.46, 95% CI: 9.44-13.91, P < 0.001], between 40 and 60 years [OR: 10.43, 95% CI: 8.85-12.30, P < 0.001], and between 18 and 40 years [OR: 2.48, 95% CI: 2.16-2.84, P < 0.001]; illiterates (OR: 1.76, 95% CI: 1.45-2.15, P < 0.001); and farmers (OR: 1.32 95% CI: 1.12-1.55, P = 0.001). Conclusion The study presents the utilization of eye care among rural South Indian adults. Almost 84.46% of individuals had not undergone any eye examination. Robust measures to promote eye care management would help in effective utilization of eye care services among rural adults.

Abstract
PURPOSE To assess associations between visual function and on-road driving performance evaluated by a certified driving rehabilitation specialist (CDRS). METHODS Adults aged 70 and older enrolled and completed assessments of visual acuity, contrast sensitivity, visual processing speed, visual field sensitivity, motion perception and spatial ability. At follow-up, on-road driving performance was evaluated on a 15-mile route. Age-adjusted odds ratios and 95% confidence intervals (95% CIs) were used to associate worse CDRS composite score and CDRS global rating for those with poorer visual function compared to those with better scores and ratings. RESULTS For the 144 participants who enrolled, completed vision testing and the on-road driving evaluation, the mean age was 79.2 (5.1) and 45.8% were female. The odds of worse CDRS global rating and composite score were significantly associated with moderately and severely impaired visual processing speed under divided attention (all p < 0.05). Those with poorer motion perception were at greater odds of a worse CDRS composite score (OR: 2.67, 95% CI: 1.14-6.26). CONCLUSIONS The CDRS composite score of on-road driving performance by older adults was associated with slowed visual processing and impaired motion perception, suggesting that older driver performance, as rated by a CDRS, relies on visual skills. The CDRS global rating was also associated with impaired visual processing speed. The literature suggests impairments in these same visual functions elevate crash risk. While the results provide additional evidence suggesting these functional measures are associated with driving, further work is needed to identify and assess visual measures most closely related to driving safety and performance among older adults to better inform interventions, policy and future research.

Abstract
PURPOSE To provide the prevalence of vision impairment and blindness among 250,000 school children aged 6 to 17 years, screened in Tamil Nadu, India. METHODS The study was conducted between 2016 and 2019 as a part of the school eye screening program in Kanchipuram district, Tamil Nadu. The clinical examination included basic vision testing, objective refraction, subjective acceptance, spectacle dispensing, and a posterior segment evaluation. The prevalence of vision impairment, blindness, low vision, and the association with other demographic variables using logistic regression were calculated. RESULTS A total of 250,052 children were screened in 1047 schools and the prevalence of vision impairment, blindness, and low vision in Kanchipuram district was 3.83%, 0.01%, 0.19%, respectively. The major causes for vision impairment, blindness, and low vision were refractive errors (3.05%), high myopia (0.002%), and refractive amblyopia (0.04%), respectively. Vision impairment was significantly associated with urban location (OR = 1.42, 95% CI 1.36-1.48, p < .0001), females (OR = 1.11, 95%CI - 1.08-1.15, p < .0001), private schools (OR = 2.43, 95%CI - 2.35-2.42, p < .0001), higher secondary class grade (OR = 1.69, 95%CI - 1.61-1.77, p = .001), high-school class grade (OR = 1.65, 95%CI - 1.58-1.72, p = .001) and middle school class grade (OR = 1.53, 95%CI - 1.47-1.59, p = .001). CONCLUSION This large-scale school eye screening reports a comparatively lower prevalence of vision impairment, blindness, and low vision when compared to other studies conducted around the world. Although the overall prevalence is relatively low, the causes are mostly refractive. Urban, female, private school-going children aged 11-17 are at higher risk.

Abstract
PURPOSE The purpose of this study is to report the distribution of astigmatism among school children in South India. METHODS The study was conducted as part of a national school eye screening project named 'Refractive Error Among Children' (REACH) between 6 and 17 years of age. Children underwent presenting visual acuity screening, external eye examination, screening for color vision deficiency, and non-strabismic binocular vision anomalies. Those who failed screening underwent, objective and subjective refraction, and identification of other ocular conditions. Astigmatism was defined as cylindrical power greater than 0.50D. Refractive errors were classified into myopia (≤0.50D), hyperopia (≥0.75D), and other refractive errors (between -0.50D and +0.75D). The data on astigmatism were analyzed and were deduced into its vector components (M, J0 and J45). Descriptive statistics and regression analysis were performed. RESULTS Data of 245,565 children from 1047 schools were taken for analysis. The average age was 11.63 ± 3.32 (range:6-17) years. After screening, refractive errors and astigmatism was found to be 6.57% (n = 16157) and 3.69% (n = 9064), respectively. Astigmatism among children aged 6 to 10 years was 1.37%. The mean cylindrical power, J0, and J45 was found to be 1.93 ± 1.06D, 0.06 ± 0.59D, and 0.43 ± 0.81D, respectively. Linear regression showed a decreasing trend in the cylindrical component (p < .001) and shift towards less positive J0 values (p < .001). Higher proportions of astigmatism more than 1.50 D (1.83%,n = 4578) and unilateral astigmatism (1.20%,n = 2952) are evident among refractive errors. CONCLUSION More than 50% of children who failed vision screening with refractive errors presented with astigmatism. Prevalence was higher among primary school children. Presence of higher magnitude and unilateral astigmatism is amblyogenic and needs early intervention.

Assi L, Kozhaya K, Swenor BK, Reed NS. Vision Impairment and Patient Activation among Medicare Beneficiaries. Ophthalmic Epidemiol 2022; 30:1-7. [PMID: 35593136 PMCID: PMC10212527 DOI: 10.1080/09286586.2022.2078495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2021] [Revised: 04/25/2022] [Accepted: 05/11/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Low patient activation is associated with poor patient outcomes. People with vision impairment may have low patient activation as a result of communication and access barriers. We examined the association of patient activation with vision impairment. METHODS Cross-sectional study using the 2016 Medicare Current Beneficiary Survey. Older Medicare beneficiaries, without dementia, who completed the topical patient activation questionnaire were included. The primary exposure was self-reported vision impairment (no vision impairment, a little vision impairment, a lot of vision impairment), and the secondary exposure was dual sensory impairment (no sensory impairment, vision impairment only, hearing impairment only, dual sensory impairment). Patient activation scores were categorized as low, moderate, or high based on their distribution around the mean. Multivariable-adjusted ordinal regression models examined the association of patient activation with vision impairment, and then with dual sensory impairment. RESULTS In total, 6,683 participants were included. Those with a little vision impairment had 20% lower odds of higher patient activation (odds ratio [OR] = 0.80, 95% confidence interval [CI] = 0.71-0.90), and those with a lot of vision impairment had 26% lower odds of higher patient activation (OR = 0.74, 95% CI = 0.55-0.98). In the second model, having vision or hearing impairment only was associated with lower odds of higher activation than having no sensory impairment. Having dual sensory impairment was associated with even lower odds of higher activation. CONCLUSION Older Medicare beneficiaries with sensory impairment may be a group to target to improve patient activation levels, which could potentially improve health outcomes and health care utilization patterns in this population.

The longitudinal association between cognitive impairment and incident visual impairment in a multiethnic Asian population: a prospective cohort study. Age Ageing 2022; 51:6593706. [PMID: 35639799 DOI: 10.1093/ageing/afac107] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 02/17/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND The relationship between baseline cognitive impairment (CI) and incident visual impairment (VI) in Asians is unclear. OBJECTIVE To determine the associations between baseline CI with incident VI and visual acuity (VA) at 6-year follow-up in multiethnic Asians. DESIGN Cohort. SETTING Population-based. SUBJECTS Two thousand three hundred and twenty-four adults aged ≥60 years from the Singapore Epidemiology of Eye Diseases Study (response rate 64%). METHODS CI was defined using the validated Abbreviated Mental Test (AMT). VA was objectively measured using a LogMAR chart. Any incident VI was defined as having no VI (Snellen's VA better than or equal to 20/40) at baseline but present (VA worse than 20/40) at 6-year follow-up. VI severity was defined according to the International Classification of Diseases, 11th Revision. Associations were assessed using logistic and linear regression models. RESULTS Of the 2,324 participants, 248 had CI at baseline. Presence of baseline CI was associated with more than twice the odds of any incident VI, incident mild and moderate-severe VI (OR [95% confidence interval]: 2.48 [1.55-3.90], 2.07 [1.17-3.55], and 2.61 [1.36-4.93], respectively) and worse VA (β [95% confidence interval]: 0.026 [0.006-0.046]) at 6-year follow-up. The leading causes of incident VI were cataract and under-corrected refractive error. CONCLUSIONS Older adults with CI had more than double the odds of VI development and poorer VA than their cognitively intact counterparts, and most causes of incident VI were correctable. Strategies such as targeted vision screening and early intervention for early detection and management of vision loss in patients with cognitive decline are warranted.

Abstract
PURPOSE This project aims to describe the characteristics of patients with visual impairment referred from a tertiary academic hospital in Jordan for a comprehensive low vision evaluation and to study its impact on their functional needs. METHODS A retrospective analysis of the records of 108 patients from the ophthalmology clinic at Jordan University Hospital over the period from January 2014 to December 2018 was performed. Gathered information included age, gender, clinical diagnosis, family history of ocular disease, and type of low vision aid prescribed and its impact on patients' functional needs. RESULTS The mean age was 44.64 years (range 4-88). Most participants were in the 19-60 years age group (50.0%). Fifty percent of the participants were the offspring of consanguineous marriages. The main cause of visual impairment in this cohort was retinitis pigmentosa, followed by diabetic retinopathy. The majority of low vision aids were prescribed for near distance tasks, and reading spectacles were the most prescribed visual aid. Eighty-nine percent of patients reported functional improvement and retained their visual aids upon follow-up. CONCLUSION Retinitis pigmentosa was the main cause of visual impairment in this cohort of patients referred from a tertiary academic hospital for low vision assessment. We report a consanguinity rate of 50%. The overwhelming majority of patients reported functional improvement and retained their visual aids upon follow-up. Awareness and integration of low vision services into a multidisciplinary approach and improving referral protocols is essential to better address the needs of patients with visual impairment. Familial counselling regarding consanguineous marriages and emerging research to treat inherited retinal diseases should be pursued.

Abstract
BACKGROUND More than 2 billion people are thought to be living with some form of vision impairment worldwide. Yet relatively little is known about the wider impacts of vision loss on individual health and well-being, particularly in low- and middle-income countries (LMICs). This study estimated the associations between all-cause vision impairment and self-reported symptoms of anxiety and depression among older adults in Kogi State, Nigeria. METHODS Individual eyes were examined according to the standard Rapid Assessment of Avoidable Blindness methodology, and anxiety and depression were assessed using the Washington Group Short Set on Functioning-Enhanced. The associations were estimated using multivariable logistic regression models, adding two- and three-way interaction terms to test whether these differed for gender subgroups and with age. RESULTS Overall, symptoms of either anxiety or depression, or both, were worse among people with severe visual impairment or blindness compared with those with no impairment (OR=2.72, 95% CI 1.86 to 3.99). Higher levels of anxiety and/or depression were observed among men with severe visual impairment and blindness compared with women, and this gender gap appeared to widen as people got older. CONCLUSIONS These findings suggest a substantial mental health burden among people with vision impairment in LMICs, particularly older men, underscoring the importance of targeted policies and programmes addressing the preventable causes of vision impairment and blindness.

Abstract
PURPOSE To assess the correlation of the worldwide prevalence of visual impairment and depressive disorders. METHODS This is an ecologic study on Global Burden of Disease 2019 data. Global and national prevalence numbers and rates of vision impairment (VI) and depressive disorders were obtained from database. The human development index (HDI) and socio-demographic index (SDI) were derived from international open databases. Main outcome measures were the correlation of the VI and depressive disorders in total and different age, sex, and socioeconomic subgroups. RESULTS In 2019, the worldwide prevalence of total VI and total depressive disorders were 9.6% (95% Uncertainty Interval (UI): 8.0-11.3) and 3.8% (95% UI: 3.4-4.2), respectively. The prevalence rates of total VI (r = 0.38, P < 0.001) as well as cataract (r = 0.43, P < 0.001), age-related macular degeneration (AMD) (r = 0.32, P < 0.001), refractive disorders (r = 0.19, P < 0.001) and near vision loss (r = 0.33, P < 0.001) correlated, positively, with dysthymia. In addition, the prevalence rates of glaucoma (r for total depressive disorders = 0.37, P < 0.001 and r for major depressive disorders (MDD) = 0.38, P < 0.001) and AMD (r for total depressive disorders = 0.37, P < 0.001 and r for MDD = 0.28, P < 0.001) had a positive correlation with MDD and total depressive disorders. The correlations remained significant in sociodemographic subgroups. CONCLUSION There was a significant correlation between national prevalence rates of VI and ocular disabilities with depressive disorders, worldwide.

Abstract
OBJECTIVE To test the association of material deprivation and the utilization of vision care services for young children. STUDY DESIGN We conducted a population-based, repeated measures cohort study using linked health and administrative datasets. All children born in Ontario in 2010 eligible for provincial health insurance were followed from birth until their seventh birthday. The main exposure was neighborhood-level material deprivation quintile, a proxy for socioeconomic status. The primary outcome was receipt of a comprehensive eye examination (not to include a vision screening) by age 7 years from an eye care professional, or family physician. RESULTS Of 128 091 children included, female children represented 48.7% of the cohort, 74.4% lived in major urban areas, and 16.2% lived in families receiving income assistance. Only 65% (n = 82 833) had at least 1 comprehensive eye examination, with the lowest uptake (56.9%; n = 31 911) in the most deprived and the highest uptake (70.5%; n =19 860) in the least deprived quintiles. After adjusting for clinical and demographic variables, children living in the least materially deprived quintile had a higher odds of receiving a comprehensive eye examination (aOR 1.43; 95% CI 1.36, 1.51) compared with children in the most materially deprived areas. CONCLUSIONS Uptake of comprehensive eye examinations is poor, especially for children living in the most materially deprived neighborhoods. Strategies to improve uptake and reduce inequities are warranted.

Abstract
The purpose of this study was to develop a model describing the process of how older adults with age-related macular degeneration develop physical activity self-efficacy. The primary aim of this research was to determine how adults with age-related macular degeneration living in a southeastern metropolitan area develop physical activity self-efficacy. Sixteen older adults with age-related macular degeneration participated in face-to-face interviews and observations of their regular physical activity. Grounded theory approach was used to identify emerging themes and a model describing the development of physical activity self-efficacy in this cohort. Five themes related to the development of physical activity self-efficacy emerged: 1) physical activity engagement, 2) self-management behaviors, 3) physical activity determinants, 4) strategies, and 5) self-perceived benefits. These themes were analyzed to produce a preliminary model describing the development of physical activity self-efficacy in older adults with age-related macular degeneration. Findings provide a preliminary model, which practitioners can use to facilitate self-efficacy and participation in physical activity in older adults with age-related macular degeneration.

Abstract
Objective: This study aims to investigate the association of sleep duration with vision impairment (VI) in middle-aged and elderly adults. Methods: This cross-sectional study used the data from the baseline survey of the China Health and Retirement Longitudinal Study (CHARLS) 2011–2012, a national survey of adults aged 45 years or older. Weighted multilevel logistic regression models were used to evaluate the association between self-reported sleep duration and VI. Results: Of the 13,959 survey respondents, a total of 4,776 (34.2%) reported VI. The prevalence of short (≤6 h/night) and long (>8 h/night) sleep durations was higher among respondents with VI than those without VI (P < 0.001). Multilevel logistic regression models showed that compared with a sleep duration of 6–8 h/night, a sleep duration of ≤6 h/night was associated with a 1.45-fold [95% confidence interval (CI) = 1.34–1.56] higher VI risk, and a sleep duration of >8 h/night was associated with a 1.18-fold (95% CI = 1.03–1.34) higher VI risk, after adjusting for sociodemographic data, lifestyle factors, and health conditions. Vision impairment was associated with short sleep duration in respondents from all age or gender categories. However, VI was associated with long sleep duration in respondents from the elderly or female categories. The association between VI and long sleep duration disappeared in respondents of middle-aged or male categories. Conclusions: The potential impact of sleep on the risk of visual functions requires further attention. A more comprehensive and integrated health care and rehabilitation system covering vision and sleep is also needed.

Abstract
OBJECTIVES This study assessed the relationship between self-reported impairments of vision, hearing, and dual sensory impairment, and change in self-rated health/mortality status over a 5-year period. METHODS Data came from the National Health and Aging Trends Study, a nationally representative survey of Medicare beneficiaries ages 65 and older. Analyses consisted of a series of ordinal logistic regressions stratified by sex. RESULTS For both women and men, self-reported sensory impairments were not statistical predictors of self-rated health/mortality, when other dimensions of health, such as physical functioning, participation, and activities of daily living functioning were included in models. DISCUSSION Understanding how self-reported sensory impairments impact self-rated health could assist in targeting rehabilitation strategies to older adults who experience sensory impairments.
