Optic disc cupping as clinically estimated from photographs

B E Klein et al. Ophthalmology. 1987 Nov.

Abstract

Cup-to-disc ratios of 204 right eyes were evaluated by two clinicians and by a trained grader using a standardized grading scheme. Mean measurements by the grader were greater than estimates made by either clinician. The measurement scheme used by the trained grader has a high degree of reliability and validity. The standard protocol provides an objective assessment of optic disc cupping and could be easily adapted for office use.
