Angio-OCT在眼底疾病综合诊疗过程中的应用进展

Application progress of Angio-OCT in comprehensive diagnosis and treatment of ocular fundus diseases

光学相干断层扫描血管成像(Angio-OCT)是一种新型的成像技术,用来检测眼底血液流动;相较于传统OCT,Angio-OCT具备分辨率高、安全快速、无创性等优势;实现了无创定量测量视网膜、脉络膜血管和血流灌注等眼部解剖结构。本文回顾了Angio-OCT定量测量血流灌注的基本原理,以及在脉络膜新生血管形成、中心性浆液性脉络膜视网膜病变、糖尿病性视网膜病、视网膜动静脉阻塞和息肉样脉络膜血管病变等眼底疾病的应用进展,对其优缺点进行系统的概述,用以加深眼科临床工作者对Angio-OCT这一新型检查手段的全面认知。

Optical coherence tomography angiography(Angio-OCT)is a new imaging technology used to detect blood flow in the fundus.Compared with traditional OCT,Angio-OCT has the advantages of high resolution,safety,speed,and non-invasiveness.Non-invasive quantitative measurement of ocular anatomical structures was achieved such as retina,choroidal blood vessels and blood perfusion.This article reviews the basic principles of Angio-OCT quantitative measurement of blood flow transplantation and its application in fundus diseases such as choroidal neovascularization,central serous chorioretinopathy,diabetic retinopathy,retinal arteriovenous and polypoid choroidal vascular diseases.The shortcomings are summarized to deepen the ophthalmology clinicians comprehensive knowledge of Angio-OCT,as a new inspection method.
