To evaluate safety, efficacy and ease of measurement of epithelial thickness and to investigate to investigate patterns and descriptive statistics of epithelium distribution, in a keratoconic patient based on anterior-segment optical coherence tomography (AS OCT). To investigate patterns and descriptive statistics of epithelium distribution

Two hundred fifty two cases diagnosed with keratoconus (group A), were subjected to series of AS OCT corneal epithelial imaging, in comparison to an age-matched cases, of non-keratoconic population (group B). We investigated epithelial thickness and epithelial topographic thickness distribution
Mean epithelial thickness was 55.65 ± 1.22 for group A, and 51.97 ± 0.70 for group B. Topographic epithelial thickness variability for group A was 9.80 ± 0.41 ?m, and for group B, 1.53 ± 0.21 ?m.
Anterior-segment OCT epithelial imaging also supports our previous findings with high frequency ultrasound measurements, of the increase, of overall epithelial thickness in keratoconic eyes, in comparison to normal. AS-OCT further offers ease of use and possibly higher predictability of measurement, which may be significant advantage.
