Diagnosis of keratoconus progression by Fourier-domain optical coherence tomography should be correlated with Scheimpflug tomography

In a recent article, Ouanezar et  al.1 studied 134 keratoconus cases to define a new anatomic criterion for progressive keratoconus based on corneal optical coherence tomography (OCT). The authors stated that corneal thickness was better evaluated by OCT than by scanning-slit corneal topography on the basis of an interobserver rep eatability comparison between the Orbscan IIz topographer (Bausch + Lomb Surgical, Inc.) and the RTVue Fourier-domain OCT device (Optovue, Inc.). In an earlier study, Meyer et al.
