A significant difference in preoperative VA, foveal flattening, foveal EZ and ELM damage, EZ reflectivity and presence of HRF in the ONL was detected between groups(all <em>p</em> < 0.001).The segmenter showed good agreement with human assessment in both qualitative and quantitative variables. The Optimizable Naïve Bayes model was the best performing ML model and showed an accuracy of 86.2 % in detection of cases with postoperative VA>0.4 logMar.</p></div><div><h3>Conclusions</h3><p>The results confirm the prognostic relevance of EZ and ELM integrity and reflectivity, foveal flattening, ONL cysts and ONL HRF in macula off RRD, and, for the first time in literature, reports feasibility of the segmentation of these factors in preoperative OCT B scan images. We also report good classification performances of Naïve Bayes models based on OCT biomarkers, preoperative VA and age in distinguishing patients that should expect a postoperative VA>0.4 logMar at 6 months from surgery.</p></div>","PeriodicalId":100071,"journal":{"name":"AJO International","volume":"1 1","pages":"Article 100008"},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S295025352400008X/pdfft?md5=8e585ce090a61f313a541c635052c4b4&pid=1-s2.0-S295025352400008X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140344184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, it can be assumed that quite a few soldiers took part in the war without necessary correction and therefore with reduced visual acuity. The low, though slightly higher prevalence of glasses among US generals in the photos can best be explained by the better availability in the industrial north and the significantly better opportunities of import.</p></div>","PeriodicalId":100071,"journal":{"name":"AJO International","volume":"1 1","pages":"Article 100007"},"PeriodicalIF":0.0,"publicationDate":"2024-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950253524000078/pdfft?md5=a6a717b44678d7bc46afa5796d888f22&pid=1-s2.0-S2950253524000078-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140341816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
