The survival rates were investigated using life tables and Cox regression analysis.Results: The overall incidence rate was 1.7 per million. Incidence rates varied across age groups, peaking in the 75+ age group. Carcinomas (43%), melanomas (30%), and lymphomas (20%), were the most prevalent malignancies. Of the total cases with reported treatment, surgical intervention was undertaken in 64.5% of the patients. The 5-year overall survival rates were 90.4% for lymphomas, 73.8% for melanomas, and 72.9% for carcinomas.

The mean interval between the onset of CRVO and NVG was 507 days. Neither macular edema nor central macular thickness at baseline was correlated with the development of NVG (p =.104 and .25, respectively).

The accuracy of the responses was evaluated by two board-certified ophthalmologists and scored on a scale of 1 to 5. Readability was assessed using the Simple Measure of Gobbledygook (SMOG), Flesch-Kincaid Grade Level (FKGL), and Flesch Reading Ease (FRE) scores. Descriptive, treatment-related, and follow-up-related questions were analyzed, and statistical comparisons between these categories were performed.Results: The mean accuracy score for the responses was 4.48 ± 0.57 on a 5-point Likert scale. The interrater reliability, with an intraclass correlation coefficient of 0.769, indicated a strong level of agreement. Readability scores revealed a SMOG score of 15.49 ± 1.74, an FKGL score of 14.95 ± 1.95, and an FRE score of 27.41 ± 9.71, indicating that a high level of education is required to comprehend the responses.

This data was collated, cleaned and analysed using IBM SPSS (version 27) for frequency, mean, median and interquartile ranges.Results: Results show that over a 10-year period (2014-2023) the number of certifications in Northern Ireland has increased to a point where they are aligned with figures from other regions of the United Kingdom (UK). Results show that more people are certified as SSI than SI in Northern Ireland (NI) which is in contrast to figures reported in England and Wales. More females are certified than males in NI. Similarly to England and Wales, the most common cause of certification of visual impairment in adults in NI is Age-Related Macular Degeneration, accounting for around 50% of certifications annually. The second most common cause is glaucoma followed by diabetic eye disease (DED). In working age adults, DED is the leading cause of certification.Conclusion: The results from 10 years of certification data in NI show common themes with other high-income countries, including increased certification, particularly among females, and the most common causes of certification remain AMD, glaucoma and DED.","PeriodicalId":19607,"journal":{"name":"Ophthalmic epidemiology","volume":" ","pages":"1-8"},"PeriodicalIF":1.7,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A mixed-effects model was used to analyze influential factors. Studies were searched using PubMed, OVID, Cochrane library, and EBM reviews.Results: The mean improvements in visual acuity (VA) for dichoptic and monocular training were 0.153 logMAR and 0.162 logMAR, respectively. In the dichoptic training subgroup, the mean VA improvements were 0.201 logMAR, and 0.145 logMAR for strabismic and anisometropic amblyopia, respectively. In the monocular training subgroup, the mean VA improvements were 0.171 logMAR, and 0.143 logMAR for strabismic and anisometropic amblyopia, respectively. The mean improvements in stereopsis of dichoptic training and monocular training were 1.201 octaves and 1.661 octaves, respectively. Baseline visual acuity of the amblyopic eye and training duration were significant factors influencing visual gains. We found no significant impacts of age, astigmatism, and baseline stereopsis on visual acuity and stereopsis outcomes.Conclusions: This IPD meta-analysis provides evidence that both monocular and dichoptic training yield different visual acuity outcomes in treating unilateral amblyopia. Subgroup analysis suggests that strabismic amblyopia may respond differently to dichoptic training. Baseline visual acuity of the amblyopic eye and training duration are significant factors influencing visual gains. We believe that a more personalized training program could help restore binocularity in patients with monocular amblyopia.","PeriodicalId":19607,"journal":{"name":"Ophthalmic epidemiology","volume":" ","pages":"1-15"},"PeriodicalIF":1.7,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improvement in age-specific prevalence since 2000 was less than the Vision 2020 target (-25%) for all subcategories of VI; improvement in blindness was the only category close to the goal (about 80-100% of goal across SSA sub-regions).Conclusions: The SSA age-specific prevalence of VI has generally improved since 2000, especially for blindness. However, the number of VI cases has increased with population growth and aging, and Vision 2020 targets were not met. Because most causes of VI require individual-level clinical care, large increases in training and eye care delivery systems development/financing are critical areas of focus.","PeriodicalId":19607,"journal":{"name":"Ophthalmic epidemiology","volume":" ","pages":"1-11"},"PeriodicalIF":1.7,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143700614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
