“…Patients were assigned into etiological groups based on the following criteria: patients with ≥ 1 D difference across the most anisometropic meridian were categorized as anisometropic 61 ; patients who had heterotropia on examination either at distance or near or had a history of strabismus were categorized as strabismic (S); while patients who were affected by both were categorized as mixed etiology (SA) 60 , 61 . For anisometropic patients, a distinction was made whether they had purely spherical anisometropia (A)—≥ 1 Dsph difference between eyes—or both spherical and astigmatic anisometropia (AA)—≥ 1 Dsph & ≥ 1 Dcyl difference between eyes 62 . Furthermore, astigmatism was also considered by itself: a patient was categorized as having astigmatism if the amblyopic eye had ≥ 0.75 cylinders regardless of the dominant eye’s refraction status.…”

Dichoptic therapy is a promising method for improving vision in pediatric and adult patients with amblyopia. However, a systematic understanding about changes in specific visual functions and substantial variation of effect among patients is lacking. Utilizing a novel stereoscopic augmented-reality based training program, 24 pediatric and 18 adult patients were trained for 20 h along a three-month time course with a one-month post-training follow-up for pediatric patients. Changes in stereopsis, distance and near visual acuity, and contrast sensitivity for amblyopic and fellow eyes were measured, and interocular differences were analyzed. To reveal what contributes to successful dichoptic therapy, ANCOVA models were used to analyze progress, considering clinical baseline parameters as covariates that are potential requirements for amblyopic recovery. Significant and lasting improvements have been achieved in stereoacuity, interocular near visual acuity, and interocular contrast sensitivity. Importantly, astigmatism, fixation instability, and lack of stereopsis were major limiting factors for visual acuity, stereoacuity, and contrast sensitivity recovery, respectively. The results demonstrate the feasibility of treatment-efficacy prediction in certain aspects of dichoptic amblyopia therapy. Furthermore, our findings may aid in developing personalized therapeutic protocols, capable of considering individual clinical status, to help clinicians in tailoring therapy to patient profiles for better outcome.

“…Discrepancies in the criteria used to determine whether someone passes or fails vision screening could account for the differences in outcomes. In other studies, a lower rate of failed vision screening was found between 4.3% and 22.1% (13,26). Both investigations, however, were conducted on schoolchildren or pediatrics, as opposed to the current research, which screened the community, which was primarily composed of teenagers and the elderly.…”

“…Distance visual acuity, near visual acuity, IOP measurement, and ophthalmoscopy were all dependent variables on which the outcome of vision screening was reliant. Distance visual acuity was the main reason for previous vision screening failure (26,(30)(31)(32)(33), and it was ranged between 46% to 81% for various age groups. Visual acuity testing was a sensitive test to detecting changes in vision status either due to refractive or ocular disease and the effect of the visual treatment (34,35).…”

Introduction: A community vision screening is a quick eye examination that searches for potential vision problems. Screening helps to detect visual disorders early. This study intended to determine the outcomes of the vision screening. The association between demographic variables, vision testing, and vision screening outcomes was also investigated. Methods: Vision screening data conducted from 2017 to 2020 were obtained. Demographic data (age, gender, and location) and optometric findings (distance visual acuity (DVA), near visual acuity (NVA), refractive errors, intraocular pressure (IOP), and retina abnormalities) were extracted and analyzed. The pass or fail vision screening and causes were determined. Results: Thirty-five percent (35%) were failed the vision screening. The elderly was the most likely to fail (17%). The females and males showed an equal proportion of failure rate. Those who failed screening in urban areas (27%) were greater than in rural areas (8%). Reduced DVA was the most common reason for failed vision screening, followed by reduced NVA. Age (p<0.001) and location (p<0.001) was significantly linked with the outcome of vision screening. DVA (p<0.001), NVA (p<0.001), IOP measurement (p=0.006) and ophthalmoscopy findings (p<0.001) demonstrated significant association with vision screening results. Conclusion: The failure rate in community vision screening was high. Age, location, DVA, NVA, IOP measurement, and fundus evaluation were associated with vision screening outcomes. Outreach initiatives help identify potential vision problems in the community. This evidence is vital for determining the need for treatment and management of optometry services and planning for targeted vision screening programs, thereby preventing vision loss.

“…This is a widely used criterion 45,66,72 for children aged 4-5 years 45,73 (as recommended by Public Health England) 36 as well as those 5-6 years of age. 74 Wilkinson and Wilson 75 questioned whether screening for myopia in New Zealand meets the Wilson and Jungner criteria; a process previously undertaken in the UK by Thomson and Evans. 76 Wilkinson and Wilson found that paediatric vision screening would meet seven of the 10 criteria, and recommended further research on developing vision screening to identify early myopia and provide treatment to slow its progression.…”

Myopia prevalence has increased in the UK at age 10-16y, but little is known about younger children. We hypothesise that if the 'myopia epidemic' is affecting young children, then there will be increasing rates of bilateral reduced unaided vision (V) at vision screenings of children 4-5 years of age. Methods: Retrospective anonymised data from computerised vision screening at age 4-5 years were analysed from serial cross-sectional data. Refractive error is not assessed in UK vision screening, so vision was investigated. Data were only included from schools that screened every year from 2015/16 to 2021/22. The criterion used was unaided monocular logMAR (automated letter-by-letter scoring) vision >0.20 in both the right and left eyes, so as to maximise the chances of detecting bilateral, moderate myopia rather than amblyopia. Results: Anonymised raw data were obtained for 359,634 screening episodes from 2075 schools. Once schools were excluded where data were not available for every year and data were cleaned, the final database comprised 110,076 episodes. The proportion (percentage and 95% CI) failing the criterion from 2015/16 to 2021/22 were 7.
