Repeatability and reproducibility were evaluated through within-subject standard deviation (Sw), coefficient of variation (CoV), intraclass correlation coefficient (ICC) and Bland-Altman plots (bias and limits of agreement (LoA)).</div></div><div><h3>Results</h3><div>The TMH measurement with ICP Tearscope showed both, a moderate intrasession repeatability (Sw = 0.045, CoV < 19.82 %, ICC > 0.684) and interobserver reproducibility (Sw = 0.032, CoV < 14.09 %, ICC > 0.926).</div><div>The NIBUT measurement showed worse intrasession repeatability in the DED group (CoV = 27.53 %) than in the Control group (CoV = 13.31 %). Even though similar Sw, LoA and ICC values were observed in both groups (Sw = 2.55 s and 2.34 s; LoA = −6.60 to 5.18 s and −4.82 to 6.51 s, Control and DED respectively, ICCs > 0.95). Interobserver reproducibility indicated a moderate amount of variability with CoV ≤ 15.01 % recorded in both groups.</div><div>Agreement between the two devices was poor. Limits of agreement were not clinically acceptable for TMH (LoA = −0.19 to 0.14 mm and −0.16 to 0.13 mm, Control and DED, respectively) and for NIBUT (LoA = −12.74 to 14.08 s and −12.19 to 12.87 s, Control and DED, respectively).</div></div><div><h3>Conclusions</h3><div>ICP Tearscope provides TMH and NIBUT measurements that show weak repeatability and moderate interobserver reproducibility. This device is not interchangeable with the Keratograph 5 M.</div></div>","PeriodicalId":49087,"journal":{"name":"Contact Lens & Anterior Eye","volume":"48 2","pages":"Article 102333"},"PeriodicalIF":4.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142629926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
