ABSTRACT
Optical coherence tomography (OCT) has played a revolutionary role in the development of ophthalmology.Since the 1990s,it has been constantly improved in terms of speed,resolution and sensitivity.The technique has also seen a variety of extensions aiming to assess ftmctional aspects of the tissue.Doppler combined with OCT technology (DOCT) can provide 3D vascular images,also referred to as the OCT angiography.DOCT can achieve visualization,quantitative blood flow,scanning of layer retinal blood vessels,and the scanning speed is fast.It has depth resolution,clear image.As a new noninvasive optical imaging technique,DOCT can realize retinal vascular network images and provide meaningful image data.It is a major breakthrough on the eye detection methods and helpful in diagnosis,monitoring for the eye disease in the future.This article reviews the application progress of DOCT in eye diseases.
