Total CA of 1.5 mm region centered on the fovea was 0.49 ± 0.08 mm<sup>2</sup> and 0.55 ± 0.09 mm<sup>2</sup>, respectively (p = 0.002); total CVI of 1.5 mm region centered on the fovea was 63.66% ± 1.23 and 64.90% ± 1.07, respectively (p < 0.001); total CA of 6 mm region centered on the fovea was 1.61 ± 0.22 mm<sup>2</sup> and 1.80 ± 0.33 mm<sup>2</sup>, respectively (p = 0.003); the total CVI of 6 mm region centered on the fovea was 63.85% ± 1.16 and 64.87% ± 1.12, respectively (p < 0.001). There was no correlation between mRss score and Raynaud severity and CMT, CVI and CTs; however, there was a positive correlation between the mRss and the Raynaud severity (p = 0.0004, r = 0.507).</p><p><strong>Conclusion: </strong>This study found that choroidal thickness and CVI decreased in SSc patients. A decrease in CVI may be an indicator of damage, especially in luminal structures.</p>","PeriodicalId":14473,"journal":{"name":"International Ophthalmology","volume":"45 1","pages":"181"},"PeriodicalIF":1.4,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144015607","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}
