Progression of visual field loss in open angle glaucoma in the Melbourne Visual Impairment Project

Abstract

Purpose: To quantify the progression of visual field loss in participants with open angle glaucoma. Methods: Cluster random samples of 3271 participants participated in this study. Each participant underwent a standardized ophthalmic examination, which included intraocular pressure measurement, Humphrey 24-2 Fastpac visual field testing and stereophotography of the optic disc. At baseline 118 participants were identified as possible, probable or definite open angle glaucoma and 74 (62.7%) of these were seen again at the follow-up examination. Progression of visual field loss was defined using three methods: the Advanced Glaucoma Intervention Study criteria, the modified Anderson criteria and..
