Receiver operating characteristic curve for central corneal basal epithelial cell density (A) and subbasal nerve density (B). The lower cutoff basal epithelial cell density to diagnose limbal stem cell deficiency was 7930 cells/mm2 and resulted in a 95.5% sensitivity and 100% specificity. The lower cutoff subbasal nerve density was 53 nerves/mm2 and resulted in an 87.0% sensitivity and 91.7% specificity.
