Variation in optical coherence tomography signal quality as an indicator of retinal nerve fibre layer segmentation error

摘要

PurposeCommercial optical coherence tomography (OCT) systems use global signal quality indices to quantify scan quality. Signal quality can vary throughout a scan, contributing to local retinal nerve fibre layer segmentation errors (SegE). The purpose of this study was to develop an automated method, using local scan quality, to predict SegE.
