Repeatability of Peripapillary Retinal Nerve Fiber Layer and Inner Retinal Thickness Among Two Spectral Domain Optical Coherence Tomography Devices

Abstract

Measurement of pRNFL and macular RNFL-GCL-IPL thickness has a high degree of repeatability for both OCT devices. Despite a high correlation between measurements of the two OCT devices and fair to excellent ICC values representing a high consistency in the measurements of the two devices, RTVue measured a thicker macular RNFL-GCL-IPL and pRNFL thickness.
