The results were compared statistically.</p><p><strong>Results: </strong>The average ASTs of the groups did not differ significantly (p > 0.05 for each). The analysis of the nasal SC diameter revealed a significant decrease in the POAG group in comparison with the PEG group, with no difference observed between the POAG and control groups (p = 0.038*). The mean nasal and temporal SC area was significantly smaller in the PEG and POAG groups compared with the control group (p < 0.001** and p < 0.001**, respectively).</p><p><strong>Conclusions: </strong>There was no significant difference in nasal and temporal AST between groups; however, the SC area was found to be smaller in glaucoma groups compared with healthy controls. The present findings should be supported by further studies.</p>","PeriodicalId":9058,"journal":{"name":"BMC Ophthalmology","volume":"25 1","pages":"87"},"PeriodicalIF":1.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11846182/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143472256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
