The Use of Bowman’s Layer Vertical Topographic Thickness Map in the Diagnosis of Keratoconus – Corrected Proof

Purpose: To evaluate the use of Bowman's layer (BL) vertical topographic thickness maps in diagnosing keratoconus (KC).Design: Prospective, case control, interventional case series.Participants: A total of 42 eyes: 22 eyes of 15 normal subjects and 20 eyes of 15 patients with KC.Intervention: Bowman's layer 2-dimensional 9-mm vertical topographic thickness maps were created using custom-made ultra high-resolution optical coherence tomography.Main Outcome Measures: Bowman's layer average and minimum thicknesses of the inferior half of the cornea, Bowman's ectasia index (BEI; defined as BL minimum thickness of the inferior half of the cornea divided by BL average thickness of the superior half of (Read more...)
