Abstract
Optical coherence tomography angiography (OCTA) is a new emerging technology that is widely used in diagnosis of ocular diseases recently.It has the capability to generate high resolution 3D angiograms of retina and choroid, dissect and visualize the flow in various layers of the retina, and provide more informations of the structure and function of the retina simultaneously.Nevertheless, OCTA is in the early stage of clinical evaluation, so studies on imaging various diseases by OCTA are still on the way.In this article, we reviewed literatures of clinical research on OCTA, and summarized its current research situation, values of optic diseases and drawbacks, which guide its clinical application. Key words: Optic coherence tomography angiography; Macular; Optic nerve
