Following PRISMA guidelines and registered in PROSPERO (CRD42024592971), the study included randomized controlled trials (RCTs) and observational studies. The eligibility criteria targeted children and adolescents aged 6 to 18 years with varying levels of outdoor exposure. Primary outcomes were axial elongation and spherical equivalent change. Studies were assessed for quality using GRADE and AMSTAR-2 tools, and data were analysed using Review Manager 5.4, with random-effects models applied when heterogeneity was significant. Fifteen studies (9 RCTs and 6 observational) were included, with a total of 16 597 participants. Outdoor activities significantly reduced or delayed the onset of myopia, with a mean axial length difference of -0.08 mm per year (95% CI: -0.09 to -0.07) and a spherical equivalent difference of 0.16 diopters per year (95% CI: 0.07 to 0.25). These differences were observed after 1 year of intervention and sustained for up to 3 years, with daily outdoor exposure ranging from 40 to 120 min. Heterogeneity was moderate to high, but sensitivity analyses confirmed the robustness of the results. While higher outdoor exposure appeared more effective in reducing myopia progression, the certainty of this evidence was rated as low due to suspected publication bias, as indicated by the GRADE analysis. Outdoor activities, especially with prolonged exposure to intense light, effectively reduce or delay the onset of myopia in children and adolescents. This study emphasizes the importance of light intensity in maximizing the benefits of outdoor interventions and highlights regional differences in effectiveness, suggesting that environmental factors play a significant role in the outcomes.</p>","PeriodicalId":6915,"journal":{"name":"Acta Ophthalmologica","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143603002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the matched cohort study of neuro-ophthalmology patients, those treated using agents other than semaglutide had NAION rates, orders of magnitude higher than a background population, presumably because referral patterns led to the enrichment of the study populations with patients at high risk of NAION. With semaglutide, the rates of NAION were 4.28 and 7.64 times higher for type 2 diabetes (T2D) and obesity, respectively, and onset of NAION was within 14 months of treatment initiation, whereas non-semaglutide NAION was evenly distributed over the 3 years of follow-up. Of four health care registry studies, each covering more than 100 000 patients, two found relative rates of NAION two to three times higher with semaglutide than without semaglutide, one found a trend towards semaglutide being associated with NAION in patients with type 2 diabetes only, and one found statistically insignificant imbalances between the two alternatives. The meta-analysis of various GLP-1 receptor agonists versus placebo or active comparator found no significant difference in rates of NAION. Prior reports of long-term glycaemia reduction being associated with early worsening of retinopathy and with NAION indicate that semaglutide may promote such events in proportion to its antihyperglycaemic potency. The association of NAION with small, crowded discs, optic disc oedema and peripapillary exudation suggests that semaglutide-related NAION may result from changes in perfusion that lead to venous dilation and, presumably, to venous congestion during relative hypoglycaemia. Given the retrospective nature of the epidemiological studies, causality cannot be inferred, but a cautious approach to the use of semaglutide and other powerful glycaemia-reducing agents seems warranted, particularly in patients with crowded optic discs, a characteristic that can be identified by proactive eye examination for disc-at-risk characteristics by the use of optical coherence tomography.</p>","PeriodicalId":6915,"journal":{"name":"Acta Ophthalmologica","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143584141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
