Based on PVD status, eyes were categorized into five newly defined PVD stages.\u0000 \u0000 \u0000 \u0000 Among 2002 eyes, PVD stages were: A) 25 (1.25%); B) 725 (36.21%); C-) 248 (12.39%); C+) 151 (7.54%); D) 851 (42.51%); X) 2 (0.1%). PVD was correlated with advanced age (P<<0.0001). Limited separation or partial separation between lamella within the posterior vitreous cortex (stage B) was noted early (68% of eyes <18 years). 34% of eyes >70 years did not exhibit complete PVD. Of 75 eyes with tractional vitreoretinal disorders, 64 (85.3%) were stage C-/C+, identifying stage C as the high risk “complication” stage.\u0000 \u0000 \u0000 \u0000 Imaging analyses using RNFL C-OCT and M-OCT scans in conjunction allows rapid assessment of PVD stage. These techniques can assist clinicians and surgeons in counseling patients and planning surgical approach. Observations confirmed progression of PVD through predictable stages and progression of PVD with age.\u0000","PeriodicalId":21178,"journal":{"name":"Retina","volume":"1015 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140749323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
