Figure 2

Receiver operating characteristic (ROC) curve of the epithelium diagnostic indices for normal, sub-clinical keratoconus and keratoconus groups.

(A) ROC curve of epithelial diagnosis indices for sub-clinical KC group versus normal group. (B) ROC curve of epithelial diagnosis indices for KC group versus normal group. (C) ROC curve of Bowman’s layer diagnosis indices for sub-clinical KC group versus normal group. (D) ROC curve of Bowman’s layer diagnosis indices for keratoconus group versus normal group. EEI, epithelium ectasia index; EEI-MAX, maximum epithelium ectasia index; EPSD, epithelium profile standard deviation; EPV, epithelium profile variation; BEI, Bowman’s layer ectasia index, BEI-MAX, maximum Bowman’s layer ectasia index; BPSD, Bowman’s layer profile standard deviation; BPV, Bowman’s layer profile variation.
