[摘要]
光学相干断层扫描血管成像(optical coherence tomography angiography，OCTA)是一种快捷的、无创的新兴成像技术，可以定性、定量分析视网膜血流灌注，在临床的应用越来越广泛。脉络膜新生血管(choroidal neovascularization，CNV)是湿性年龄相关性黄斑变性(neovascular age-related macular degeneration，nARMD)导致老年人视力丧失的主要原因，因此在nARMD中对CNV的检测十分重要。本文通过OCTA对CNV的诊断、形态、面积及血流灌注的分析，综述了其在nARMD诊疗中的研究进展。

[Abstract]
Optical coherence tomography angiography(OCTA)is a quick, non-invasive imaging technology which can both qualitatively and quantitatively analyze retinal blood perfusion that is now more widely used in clinical practice. Choroidal neovascularization(CNV)is the main cause of loss of vision in the elderly and is caused by neovascular age-related macular degeneration(nARMD). Therefore, the detection of CNV in nARMD is of extreme importance. In this paper, the research progress of OCTA in diagnosing and treating nARMD was reviewed by analyzing the diagnosis, morphology, area and blood perfusion of CNV.
