Abstract

Purpose: To evaluate the repeatability of Fourier-domain optical coherence tomography (OCT) pachymetric mapping and compare central corneal thickness (CCT) measurements by OCT, ultrasound pachymetry, and scanning-slit tomography. Setting: Doheny Eye Institute, University of Southern California, Los Angeles, California, USA. Methods: A Fourier-domain OCT system was used to map the corneal thickness in normal eyes with scans centered on the corneal vertex or the pupil. Repeatability of central and pericentral map sectors was assessed by pooled standard deviation. The CCT measurements were compared between the OCT, ultrasound, and scanning-slit devices. Results: Pupil centration (SD: 1.3 μm central, 1.8 to 3.8 μm pericentral) provided better repeatability than vertex centration (SD: 1.7 μm central, 2.4 to 5.7 μm pericentral) in all sectors (P
