Abstract:
Optical coherence tomography angiography (OCTA) is a new technology of angiography in recent years.In addition to the advantages of traditional OCT,it can observe blood flow in different retinal and choroidal segmentation slab.By using the pseudo-color,abnormal vascular structure can be distinguished from normal vascular structure of the retina.Dye injection is not needed with OCTA,which is different from fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA).OCTA provides more and more accurate blood flow information.However,like other biometric technology,OCTA has its limitations and shortcomings.This review will analyze and summarize the operating principle of OCTA,its application in ophthalmology,as well as its advantages and limitations.
