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

Figure 1

Comparative diagnostic capacity of corneal biomechanical indices. Receiver-operating characteristic curves are plotted for central-corneal-thickness-corrected corneal resistance factor (ccCRF), timein, a combined index that includes ccCRF (BiomechScore), and the combination of the three extracted factors (3FactorScore). See Methods for details on each index. Area under the curve is specified in parentheses for each index.
