Multivariate Analysis of the Ocular Response Analyzer’s Corneal Deformation Response Curve for Early Keratoconus Detection

Table 3

Diagnostic capacity of individual descriptors. Specificity, sensitivity, and cutoff value for diagnosing subclinical keratoconus are shown for the 12 corneal waveform descriptors with the highest area under the curve in decreasing order.
