Glaucoma is one of the distinguished causes of irreversible blindness. It affects about 3.54% of people over 40. Glaucoma is an optic neuropathy characterized by the progressive loss of retinal ganglion cells and their axons in the peripapillary retinal nerve fiber layer as well as distinctive changes in the optic nerve head (ONH). Visual field loss is a symptom of the damage as it progresses. Vascular insufficiency is one of the factors that may contribute to glaucoma. Given that the superficial retinal capillary plexus supplies RGCs, glaucoma could be associated with decreased superficial retinal microcirculation in the macular area. Purpose of the study: the current study aimed to evaluate the macular vessel density and GCC thickness changes in early POAG eyes and compare them with healthy eyes .patients and methods: The participants were divided into two groups according to visual field findings. Group1: included 20 eyes of 12 patients of early POAG. Group 2: included 20 eyes of 10 normal individuals. All participants underwent thorough ocular examination, OCT imaging of the ONH and OCT-A of the macula. Early POAG and healthy eyes data were compared. Results: GCC thickness and whole image vessel density (wiVD) in the superficial capillary plexus were lower in the early POAG group than in healthy eyes, whereas deep capillary plexus vessel densities did not differ significantly between both groups. conclusion the inclusion of OCTA in glaucoma diagnostics helps in the early detection of glaucoma and improves our understanding of ocular blood flow changes in the disease.
