Visual Field Progression in Patients with Primary Open Angle Glaucoma, Normal Tension Glaucoma, and Primary Angle Closure Glaucoma

Abstract

Purpose: We compared visual field progression among patients with primary open-angle glaucoma (POAG), normal tension glaucoma (NTG), and primary angle-closure glaucoma (PACG).Methods: A total of 115 POAG, 123 NTG, and 92 PACG eyes were retrospectively analyzed. Global VF progression was evaluated by calculating the changes of mean deviations. To examine local VF deterioration, scotoma enlargement and deepening were analyzed in the superior, and inferior arcuate, and the central, zones.Results: The mean global rate of change in POAG eyes was -0.52 ± 0.74 dB/year, and -0.35 ± 0.41, and -0.38 ± 0.45 dB/year in NTG and PACG eyes; POAG eyes showed significantly more rapid progression than NTG and PACG eyes (p < 0.01). The superior arcuate zone of POAG eyes, the central zone of NTG eyes, and the inferior arcuate zone of PACG eyes exhibited more scotoma enlargement and scotoma deepening than did other zones.Conclusions: The superior arcuate zone of POAG eyes, the central zone of NTG eyes, and the inferior arcuate zone of PACG eyes showed greater VF progression.
