OCT epithelial mapping is a new technology that is more sensitive to subclinical keratoconus than conventional topography indices. In this interview from AAO 2017, Dr. Julie Schallhorn describes how epithelial thickness mapping can be used to identify refractive surgery candidates with biomechanically unstable corneas. Findings from her paper, published in the Journal of Cataract and Refractive Surgery, show that the OCT mapping can be used to distinguish between forme fruste keratoconus and contact lens-related warpage. Topographic corneal steepening was associated with focal epithelial thinning in keratoconus but with epithelial thickening in warpage.
