Glaucoma Specialist Optic Disc Margin, Rim Margin, and Rim Width Discordance in Glaucoma and Glaucoma Suspect Eyes.

ABSTRACT:

Purpose

To quantify the variability of 5 glaucoma specialists' optic disc margin (DM), rim margin (RM), and rim width (RW) estimates.

Design

Inter-observer reliability analysis.

Methods

Clinicians viewed stereo-photographs from 214 subjects with glaucoma or ocular hypertension and digitally marked the DM and RM. For each photograph, the centroid of each clinician's DM was calculated, and an averaged DM_centroid was determined. The axis between the DM_centroid and the fovea was used to establish 12 30-degree sectors. Measurements from the DM_centroid to each clinician's DM (DM_radius) and RM (RM_radius) were used to generate a RW (DM_radius-RM_radius) and cup-to-disc ratio (CDR) (RM_radius/
