Abstract
Optical coherence tomography angiography (OCTA) is a new vascular imaging technology based on high-resolution optical coherence tomography image analysis. It can scan the moving red blood cells in blood vessels for three-dimensional imaging of human retinal and choroidal vessels. Since the close connection of vascular endothelial cells of the blood-retinal barrier is similar to that of the blood-brain barrier, the role of OCTA in the research of pathogenesis and course monitoring of a variety of central system diseases such as Alzheimer's disease, Parkinson's disease, stroke, migraine, multiple sclerosis and optic neuromyelitis has been widely discussed. This article reviews the application and progress of OCTA in central nervous system diseases.
