Assessment of radial peripapillary capillary and macular vascular density in primary open angle glaucoma

Purpose The aim was to assess radial peripapillary capillary (RPC) and macular vascular density in eyes with primary open angle glaucoma (POAG). Patients and methods This observational cross-sectional study included 60 eyes of normal person and 67 eyes with POAG. Glaucomatous eyes were subdivided into three groups according to visual field findings; mild, moderate, and severe glaucoma (14, 27, and 26 eyes, respectively). Both RPC and macular vascular density were measured using optical coherence tomography angiography (OCTA). Visual field mean deviation was analyzed. Retinal nerve fiber layer (NFL) thickness and ganglion cell complex thickness were determined using OCT in all eyes. Results Peripapillary retinal NFL (thickness and ganglion cell complex thickness were significantly different between glaucomatous and normal eyes (P
