摘　　要：光相干断层扫描血管成像（OCTA）是一种快速的、非侵入性的新型血流成像技术，最先应用于视网膜疾病，仅在数秒内获得视网膜血管影像。与传统的光相干断层扫描（OCT）相比，OCTA具有分辨率更高、扫描速度更快、量化血流等优点，不仅能够更精确地定性分析眼部血管形态结构，更重要的是能够无创性定量测量眼部血管及血流灌注，同时还能对病变深度进行评估。随着抗新生血管药物逐渐在眼前节的应用，客观评估角膜及虹膜中的新生血管对临床指导用药并评价治疗效果具有重要作用。本文将对OCTA的特点和OCTA在角膜及虹膜疾病等眼前节疾病中的应用进行综述。Optical coherence tomography angiography （OCTA） is a rapid, noninvasive new blood flow imaging technique that was first applied to retinal retinopathy and acquired retinal vascular imaging in only a few seconds.Compared with the traditional optical coherence tomography（OCT）, OCTA analyze has the advantages of higher resolution, faster scanning speed, quantitative blood flow, etc.OCTA not only can more accurately and qualitatively analyze ocular vascular morphology, but also can measure blood vessels and blood flow perfusion noninvasively and quantitatively.With the application of anti angiogenesis drugs in the anterior segment, it is important to evaluate the neovascularization of the cornea and iris in order to guide the clinical medication and evaluate the therapeutic effect.This article reviewed the application of OCTA in ocular anterior segment diseases, such as cornea and iris diseases, etc.
