case_images: Examples of anterior corneal surface sagittal curvature maps are shown in fig. 1a for OD and fig. 1b for OS. Examples of OD and OS epithelial pachymetry maps (6 mm diameter) are provided in fig. 1c, d, respectively. OD had a central epithelial thickness (Epi CT) of 52.23 +- 0.60 mum. Overall epithelial thickness (Epi Average) was computed by taking the average of the 17 segment thickness points shown in fig. 1c, d.
case_images: a Corneal and epithelial thickness measurements for OD and OS. Values correspond to averages from 4 AS-OCT acquisitions. All values are in micrometers. Mean and standard deviations are calculated for the 4 scans. CCT = Central corneal thickness; Min = minimum; Max = maximum; stdev = standard deviation; Min CT = minimum corneal thickness; Epi min = epithelial minimum thickness; Epi max = epithelial maximum thickness. b Graph showing epithelial thickness averages for the KCN group, as reported by Kanellopoulos et al. using HF-UBM, and the respective epithelial thicknesses for OD and OS as measured by AS-OCT.

case_images: The epithelial topographic thickness variability (Epi Variability, fig. 2a) was calculated as the standard deviation of the 17 thickness points.
