Open angle glaucoma (OAG) is considered a common cause of irreversible vision loss worldwide. It is an optic neuropathy associated with progressive loss and degeneration of the retinal ganglion cell layer (RGC) and its axons (retinal nerve fiber layer; RNFL), which lead to neuroretinal rim excavation and corresponding visual field defects.~OCT Angiography (OCTA) is a promising tool for diagnosing and monitoring glaucomatous patients. It can evaluate glaucomatous damage and assess the ganglion cells' health by measuring blood flow within the optic nerve and the retina Correlation between vascular , structural and functional changes of the peripapillary retinal nerve fiber (RNFL) and macular/ganglion cell complex (GCC) can lead to early detection of glaucomatous changes.
