Differentiation of Parapapillary Atrophy Using Spectral-Domain Optical Coherence Tomography – Corrected Proof

Purpose: To develop a classification of parapapillary atrophy (PPA) based on its relationship with the location of Bruch's membrane (BM) termination in primary open-angle glaucoma (POAG) patients.Design: Cross-sectional observational study.Participants: This study analyzed 161 eyes from 161 POAG patients who had temporal β-zone PPA, the width of which was more than 200 μm on at least 1 horizontal scan image obtained by spectral-domain optical coherence tomography within the mid horizontal one third of the optic nerve.Methods: Based on the extent of BM within the PPA area, eyes were categorized as group A (intact BM; 76 eyes), group B (discontinuous BM; (Read more...)
