光学相干断层扫描血管成像在眼科的应用

摘要

光学相干断层扫描血管成像(OCTA)是一种新近出现的具有高分辨率的血管成像技术,可以三维立体成像、分层成像,并同时提供视网膜结构和功能信息等,已经广泛应用于视网膜、青光眼、视神经疾病的临床诊断及治疗中.但是OCTA技术处于其发展初期阶段,仍然具有广阔的发展空间.本文复习了大量国内外有关OCTA的临床研究,就其对视网膜和视神经解剖结构的新探索、对临床疾病诊疗价值及其局限性进行综述,以加深眼科医师对该技术的理解并指导临床应用.%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.
