Abstract: The progress of optical coherence tomography angiography (OCTA ) in recent years makes it possible to quantitatively detect the blood flow of fundus microvessels due to its fast scanning speed and high resolution, and has good repeatability in detecting the blood flow around the optic disc and in the macular region, which shows the potential ability to diagnose and monitor glaucoma as a supplement of structural OCT and perimeter. In this manuscript, the following issues were discussed: (1) The main detection parameters of OCTA for glaucoma, including the superficial peripapillary vessel density, the superficial vessel density of the macular region, and the choroidal or deep-layer microvasculature dropout (CMvD); (2) The ability and characteristics of OCTA in detecting glaucoma compared with structural OCT and perimeter; (3) How to use OCTA to detect glaucoma.
