Optical coherence tomography angiography(OCTA)is a rapid and non-invasive imaging tool, which can provide real-time flow imaging of retina and choroid. Compared with traditional angiography, OCTA can produce more detailed and high-resolution vascular images without increasing the risk due to contrast medium. Age-related macular degeneration(ARMD)is one of the major senile blinding eye diseases in the world, OCTA can well display the image of choroidal neovascularization and provide the possibility for early diagnosis and intervention. This review summarizes the OCTA image characteristics and clinical diagnostic value in patients with ARMD.
