Comparative Diagnostic Efficacy of Swept-Source OCT and Scheimpflug Imaging in Clinically Unaffected Eyes of Very Asymmetric Ectasia.

Sensitivity and specificity were 75% and 85% for Screening Corneal Objective Risk of Ectasia, 58%/86% for pentacam random forest index, 41%/90% for BAD-D, and 77%/81% for TBI, respectively.

In distinguishing healthy eyes from all ectatic eyes, AUC values were 0.978 for Screening Corneal Objective Risk of Ectasia, 0.955 for pentacam random forest index, and 0.936 for BAD-D (all P < 0.001).

Tomographical and biomechanical index (AUC 0.968) and Screening Corneal Objective Risk of Ectasia were comparable ( P = 0.06).
