Reproducibility of macular retinal nerve fiber layer and ganglion cell layer thickness measurements in a healthy pediatric population.

Purpose: To evaluate the reproducibility of Spectralis spectral domain-OCT segmented ganglion cell layer (GCL) and macular retinal nerve fiber layer (mRNFL) measurements in a healthy children population.

Methods: An observational, cross-sectional study was carried out on 79 children to measure the intraobserver reproducibility and the repeatability between a novel and an experienced operator of the segmented macular GCL and mRNFL. Interobserver and intraobserver reproducibility were defined by the intraclass correlation coefficient (ICC) and coefficients of variation (COV).
