Retrospective, consecutive case series of patients with TRS secondary to PDR are featured. Clinical notes, fundus photography, and SS-OCTA images are reviewed. The study comprised three eyes of three patients with PDR and TRS. Visual acuity and anatomic features on SS-OCTA were stable in all patients at one year or more of follow-up. Tractional retinoschisis secondary to PDR is typically nonprogressive and may be observed without surgery. SS-OCTA serves as a noninvasive and effective imaging tool to distinguish TRS from TRD and to demonstrate anatomic stability over time. <b>[<i>Ophthalmic Surg Lasers Imaging Retina</i> 2024;55:XX-XX.]</b>.</p>","PeriodicalId":19679,"journal":{"name":"Ophthalmic surgery, lasers & imaging retina","volume":" ","pages":"1-5"},"PeriodicalIF":0.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143009226","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}
