Longitudinal Evaluation of Optic Disc Measurement Variability With Optical Coherence Tomography and Confocal Scanning Laser Ophthalmoscopy

Abstract

Although both OCT and CSLO have relatively low variability for optic disc measurements, CSLO demonstrates higher measurement reproducibility for rim area compared with OCT. Variations of disc area in OCT and reference height in CSLO constituted a significant proportion of the rim area variability during longitudinal assessment.
