Comparison of Repeatability of Retinal Nerve Fiber Layer Thickness Measurement Made Using the RTVue Fourier-domain Optical Coherence Tomograph and the GDx Scanning Laser Polarimeter With Variable or Enhanced Corneal Compensation

Abstract

Repeatability characterized by CV of RNFLT measurement with the RTVue Optic Nerve Head Map scan and GDx-VCC/GDx-ECC was similar, and sufficient for clinical purposes, both in normal subjects and in glaucoma patients with different disease severity. For average peripapillary RNFLT and temporal quadrant RNFLT, repeatability of RTVue was better than that of GDx-ECC, and tended to be better than that of GDx-VCC.
