Improvement in psychiatric symptoms after strabismus surgery in adolescent patients in long-term follow-up

Strabismus Surgery for Psychosocial Reasons-A Literature Review

Introduction

Strabismus surgery may be undertaken for visual benefit, to improve or eliminate diplopia symptoms, or to restore or improve binocular single vision (BSV). In patients without visual symptoms or expected visual benefit, strabismus surgery may still be undertaken if the presence of strabismus causes the patient psychosocial symptoms. To evaluate strabismus surgery undertaken for psychosocial reasons, evidence of postoperative outcomes in this specific cohort is needed.

Methods

A systematic search of the literature was conducted (1946-2023) to identify evidence where postoperative outcomes were reported for adult patients (age 18 years and above) who had undergone strabismus surgery for psychosocial reasons.

Results

Sixty-nine papers were included in the literature review. Most sources of evidence included patients within heterogeneous cohorts of strabismus surgery outcomes, with a range of symptoms and differing surgical aims.

Discussion

In adults who underwent strabismus surgery for psychosocial reasons, improved postoperative ocular alignment and/or improved health related quality of life (HRQoL) were common. Strabismus surgery outcomes appeared to be measured satisfactorily at three months postoperatively. Additional surgical outcomes, including an expanded field of vision, unexpected BSV, improved binocular summation, improved task performance and improved eye movements have been reported, but not fully investigated. There was a lack of consensus on how postoperative success should be defined and measured. A core outcome set for strabismus has been suggested and there is potential to add to the available evidence by investigating which outcome measures are most relevant to those with strabismus and psychosocial symptoms. There is a growing need for robust evidence in this specific subgroup of patients due to a lack of evidence specifically reporting postoperative outcomes in adults with strabismus and psychosocial symptoms.

Implementing strabismus-specific psychosocial questionnaires in everyday clinical practice: mental health and quality of life in the context of strabismus surgery

BACKGROUND

Strabismus can have a great negative impact on the quality of life and the well-being of affected patients. In the past, these aspects were often neglected and, compared with somatic functioning, placed in the background. The aim of our study is to elicit factors influencing satisfaction with strabismus surgery, quality of life and expectations of surgery in order to better predict who will benefit the most and who may need further support.

METHODS

We made a selection of suitable questionnaires to assess psychosocial aspects of strabismus and decided for Adult Strabismus 20 Questionnaire, Amblyopia and Strabismus Questionnaire, Diplopia Questionnaire, Expectations of Strabismus Surgery Questionnaire and Hospital Anxiety and Depression Scale. We then translated these measures (if not available in German). The patients filled out these forms as part of their preoperative orthoptic and ophthalmological assessment as well as approximately 3 months after strabismus surgery.

RESULTS

We enrolled 59 patients in this study. Postoperative strabismus-related quality of life was higher after surgery and anxiety and depression levels were lower. Satisfaction with surgery was lower with higher postoperative angle and diplopia; the latter was also a determinant of lower postoperative quality of life. Higher expectations of strabismus surgery were present with higher depression levels and higher preoperative strabismus angle.

CONCLUSION

Our data indicate that strabismus surgery may cause a significant improvement in several psychosocial domains. There is evidence that psychosocial factors can have significant impact on expectations with surgery. Hence, it is important to consider mental health aspects of this disease in order to treat patients in the best possible way.

TFOS lifestyle: Impact of societal challenges on the ocular surface

Societal factors associated with ocular surface diseases were mapped using a framework to characterize the relationship between the individual, their health and environment. The impact of the COVID-19 pandemic and mitigating factors on ocular surface diseases were considered in a systematic review. Age and sex effects were generally well-characterized for inflammatory, infectious, autoimmune and trauma-related conditions. Sex and gender, through biological, socio-economic, and cultural factors impact the prevalence and severity of disease, access to, and use of, care. Genetic factors, race, smoking and co-morbidities are generally well characterized, with interdependencies with geographical, employment and socioeconomic factors. Living and working conditions include employment, education, water and sanitation, poverty and socioeconomic class. Employment type and hobbies are associated with eye trauma and burns. Regional, global socio-economic, cultural and environmental conditions, include remoteness, geography, seasonality, availability of and access to services. Violence associated with war, acid attacks and domestic violence are associated with traumatic injuries. The impacts of conflict, pandemic and climate are exacerbated by decreased food security, access to health services and workers. Digital technology can impact diseases through physical and mental health effects and access to health information and services. The COVID-19 pandemic and related mitigating strategies are mostly associated with an increased risk of developing new or worsening existing ocular surface diseases. Societal factors impact the type and severity of ocular surface diseases, although there is considerable interdependence between factors. The overlay of the digital environment, natural disasters, conflict and the pandemic have modified access to services in some regions.

Impact of Vision Impairment and Ocular Morbidity and Their Treatment on Depression and Anxiety in Children: A Systematic Review

TOPIC

This systematic review and meta-analysis summarizes existing evidence to establish whether vision impairment, ocular morbidity, and their treatment are associated with depression and anxiety in children.

CLINICAL RELEVANCE

Understanding and quantifying these associations support early detection and management of mental health symptoms in children with vision impairment and ocular morbidity. Additionally, this review provides evidence in favor of insurance coverage for timely strabismus surgery.

METHODS

We searched 9 electronic databases from inception through February 18, 2021, including observational and interventional studies assessing whether vision impairment, ocular morbidity, or both and their treatment are associated with depression, anxiety, or both in children. We used narrative synthesis and meta-analysis with the residual maximum likelihood method. A protocol was registered and published on The International Prospective Register of Systematic Reviews (identifier: CRD42021233323).

RESULTS

Among 28 992 studies, 28 956 studies (99.9%) were excluded as duplicates or unrelated content. Among 36 remaining studies, 21 studies (58.3%) were observational studies concerning vision impairment, 8 studies (22.2%) were observational studies concerning strabismus, and 7 studies (19.4%) were interventional studies. Vision impaired children demonstrated significantly higher scores of depression (standard mean difference [SMD], 0.57; 95% confidence interval [CI], 0.26-0.89; 11 studies) and anxiety (SMD, 0.62; 95% CI, 0.40-0.83; 14 studies) than normally sighted children. In particular, children with myopia demonstrated higher scores of depression (SMD, 0.58; 95% CI, 0.36-0.81; 6 studies) than normally sighted children. Strabismus surgery significantly improved symptoms of depression (SMD, 0.59; 95% CI, 0.12-1.06; 3 studies) and anxiety (SMD, 0.69; 95% CI, 0.25-1.14; 4 studies) in children.

CONCLUSION

Among children, vision impairment is associated with greater symptoms of depression and anxiety. Surgical treatment of strabismus improved these symptoms. Further randomized controlled trials exploring the impact of public health measures for myopia correction on mental health in children are needed. Scaling up access to strabismus surgery could improve the mental health of affected children.

Psychosocial Improvements in Children and Their Parents Following Strabismus Surgery

PURPOSE

To evaluate the psychosocial effects of strabismus surgery, the authors investigated the psychiatric symptoms and quality of life of children with strabismus and their parents.

METHODS

Children with strabismus between 6 and 18 years old (n = 39) and their parents (n = 39) were included. Psychiatric problems and the health-related quality of life were assessed with the Child Behavior Checklist and Pediatric Quality of Life Inventory, respectively. The State-Trait Anxiety Inventory for Children and Beck Anxiety Inventory were administered to children and parents, respectively. All assessments were conducted before and 3 months after strabismus surgery.

RESULTS

Compared with preoperative assessments, children with strabismus had significantly fewer psychiatric problems and a better quality of life after the surgery (P < .001). Following surgery, decreased symptom levels of anxiety scores were also obtained from children and their parents (P < .001). The amount of ocular realignment was directly correlated with improvement in social and attention problems among children (r = 0.354 and r = 0.324, respectively; P < .05).

CONCLUSIONS

Successful strabismus surgery has positive effects on psychosocial functioning and quality of life in children and their families. Surgical interventions seem beneficial for the management of strabismus in improving both physical and mental health. [J Pediatr Ophthalmol Strabismus. 2022;59(4):261-268.].

Effect of Applying Binocular Visual Training after Slanted Lateral Rectus Recession on Orthophoric Rate and Binocular Visual Function Recovery on Patients with Convergence Insufficiency-Type Intermittent Exotropia

OBJECTIVE

To explore the effect of applying binocular visual training after slanted lateral rectus recession on orthophoric rate and binocular visual function recovery on patients with convergence insufficiency-type intermittent exotropia (CI-IXT).

METHODS

A total of 76 CI-IXT child patients treated at the Strabismus and Pediatric Ophthalmology Department of our hospital from June 2019 to June 2020 were selected as the research objects, and those who met the inclusion criteria were equally divided into group A (63 eyes) and group B (61 eyes) according to the sealed envelope randomization. All child patients accepted the slanted lateral rectus recession, and after that, those in group A accepted the binocular visual training and those in group B accepted the conventional visual function rehabilitation training, so as to compare their position of eye, the best corrected visual acuity, etc., after training for statistical analysis.

RESULTS

Compared with group B after one month of surgery, group A had significantly less patients with grade I binocular vision function (P < 0.001) and more patients with grade II and III vision function (P < 0.05); between group A and group B, after 3 months and 6 months of treatment, the number of eyes with normal stereoscopic vision was significantly higher in group A (P < 0.05); at 15 days, 1 month, 3 months, and 6 months of treatment, the visual strain scores of group A were significantly lower (P < 0.001); after treatment, the number of orthophoria eyes was significantly higher in group A (P < 0.001), while the numbers of overcorrected eyes and undercorrected eyes were significantly higher in group B (P < 0.001); and the total incidence rate of adverse reactions was significantly lower in group A (P < 0.05).

CONCLUSION

Applying binocular visual training to child patients with CI-IXT after slanted lateral rectus recession can promote the recovery of binocular vision and ensure higher safety, and further study will help to establish a better solution for the affected children.

The impact of strabismus on psychosocial heath and quality of life: a systematic review

Strabismus can hinder an individual's ability to perform daily functions and negatively affect their well-being. I examine the impact strabismus has on psychosocial health and quality of life in children and adults and evaluate the challenges confronted by parents of children with strabismus. Numerous misconceptions exist regarding the impact strabismus has on overall health. Negative attitudes persist toward those affected, resulting in difficulties with self-image. Individuals with strabismus are at increased risk for both visual system and psychiatric disorders. Misinformation regarding available treatment options for children and adults with strabismus continues to exist, resulting in decreased access to care. Improved education of health care providers can increase appropriate referrals and initiation of treatment. Treatment of strabismus is not merely cosmetic and has the potential to improve psychosocial health and quality of life for children and adults with and without diplopia.

A randomized trial evaluating efficacy of overminus lenses combined with prism in the children with intermittent exotropia

BACKGROUND

To evaluate the efficacy of overminus lenses combined with prism spectacles in children of 3 to 6 years of age with intermittent exotropia (IXT).

METHODS

Sixty patients with IXT were randomly assigned to the treatment and observation groups. Each group included 30 IXT children aged 3 to 6 years. The treatment group was prescribed overminus lenses of - 2.50 D incorporated with the 2 PD base-in prisms on each side. Ocular alignment, the status of binocular vision, as well as the refraction changes were carried out and followed at 1, 3, 6, and 12 months. A revised form of the Newcastle Control Score (NCS) was used to evaluate the patients' ability to control their IXT.

RESULTS

After 12 months, the mean refractive error was 1.42 ± 1.25 D, and 1.43 ± 1.12 D for the observation and the treatment group, respectively (95% CI: - 0.61 to 0.62)); the mean exotropia control score was 5.72 ± 1.28 and 1.75 ± 1.18 in the observation and the treatment group, respectively (95% CI: - 4.63 to - 3.33); the mean near stereoacuity was 2.16 ± 0.42 log arcsec and 1.91 ± 0.26 log arcsec in the observation and the treatment group, respectively (95% CI: - 0.44 to - 0.06).

CONCLUSIONS

In our randomized clinical trial, overminus spectacles with prism significantly improved the control of IXT and stereopsis, by reducing the angle of strabismus in children with IXT. This treatment does not appear to cause myopia, at least in the manner used this series. A further randomized trial is warranted to assess the effect of overminus spectacles with prism after the treatment has been discontinued.
