Research progress of clinical application of optical coherence tomography angiography in diabetic retinopathy

Abstract

Optical coherence tomography angiography(OCTA), as a new imaging technology that has emerged in recent years, is characterized by non-invasiveness, high speed and high resolution. Compared with traditional contrast examination, OCTA is faster, safer and avoids the side effects and risks of traditional contrast agents. Now, OCTA has been gradually applied in the diagnosis, treatment and follow-up of eye diseases. Through real-time imaging of retinal choroidal blood vessels, this article reviews the research progress of clinical application of OCTA in diabetic retinopathy.
