From: Tomography-based definition of keratoconus for Down syndrome patients

  AUROC Cutoff Sensitivity (%) Specificity (%) Correct classification (%)
MCT 0.775 ≤ 480 66.67 90.91 85.15
Corneal volume 0.727 ≤ 55.3 66.67 75.32 73.27
BAD-D 0.718 > 2.23 64.58 76.32 73.50
  1. MCT = minimum corneal thickness; BAD-D = Belin Ambrosio display-total deviation
