Optical coherence tomography angiography (OCTA) is a novel imaging technique. OCTA depends on split-spectrum amplitude-decorrelation angiography algorithm that allows flow detection within retinal microvasculature. OCTA gives us the opportunity to study the choroidal, retinal, and optic nerve vasculature without the need of dye injection and its possible risks. OCTA has been used to investigate diabetic retinopathy, retinal vein occlusion, retinal artery occlusion, glaucoma, and anterior ischemic optic neuropathy. This chapter overviews the current study done using OCTA for the detection and diagnosis of various retinal and optic nerve diseases. Also, the chapter remarks several challenges that the researchers face in the analysis of the OCTA retinal images.
