The Classification of Atrophy Meeting (CAM) group recommended a new nomenclature for advanced AMD lesions, based on the affected anatomical layers on optical coherence tomography. Accordingly, the terms incomplete retinal pigment epithelium and outer retinal atrophy (iRORA) and complete retinal pigment epithelium and outer retinal atrophy (cRORA) were introduced (Guymer et al., Ophthalmology 127:394-409, 2020; Sadda et al., Ophthalmology 125:537-548, 2018). What is new GATHER1 post hoc analysis shows that treatment with avacincaptad pegol (ACP) 2 mg decreases the proportion of eyes that progress from iRORA to cRORA, and from drusen to iRORA or cRORA, compared with sham, over 6, 12, and 18 months. These findings suggest a potential role for ACP in delaying the progression of existing pre-atrophic AMD lesions.</p>","PeriodicalId":12795,"journal":{"name":"Graefe’s Archive for Clinical and Experimental Ophthalmology","volume":" ","pages":"669-677"},"PeriodicalIF":2.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11953152/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142618758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we analyzed the risk factors associated with pediatric SIOH.</p><p><strong>Methods: </strong>We retrospectively collected data from 78 children under 20 years of age who received systemic steroids during hospitalization. The data included age, gender, primary disease, intraocular pressure (IOP) before and one month after administration, total monthly steroid dose adjusted for body weight (BW), and one-month changes in red blood cell, white blood cell, and platelet counts. A multivariate analysis was used to identify risk factors related to steroid responsiveness.</p><p><strong>Results: </strong>Thirty patients (38.5%) were classified as steroid responders, and 48 as non-responders. The median IOP during the first month of steroid treatment was 24.0 mmHg (IQR; 23.0-28.3) for responders and 15.0 mmHg (IQR; 12.3-18.0) for non-responders. The Generalized Estimating Equations analysis revealed that younger age, male sex, primary disease, increase the amount of white blood cell (WBC) and total steroid dose per BW in one month were independently associated variables. The receiver operating characteristic analysis also revealed that the cutoff values for age, total monthly steroid dose, the increase amount of WBC were 11.0 years, 40.7 mg/kg and 3.40 × 10²/µl respectively.</p><p><strong>Conclusion: </strong>High-dose steroid administration, especially in male, younger patients, necessitates careful monitoring for IOP changes during treatment. WBC count also needs to be monitored during IOP follow-ups.</p><p><strong>Key messages: </strong>What is known Steroid-induced ocular hypertension (SIOH) is one of the essential complications during steroid administration, but only limited analyses have been performed in children. What is new A comprehensive analysis of multiple factors was performed that are predicted to be associated with pediatric SIOH from previous literature. Younger age, male sex, primary disease, increase the amount of WBC, and higher total monthly steroid dose were extracted as risk factors of SIOH. This study can contribute to the prediction of cases in which ophthalmologic examinations are particularly important during systemic steroid administration in children.</p>","PeriodicalId":12795,"journal":{"name":"Graefe’s Archive for Clinical and Experimental Ophthalmology","volume":" ","pages":"867-872"},"PeriodicalIF":2.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11953184/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142499151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
