光学相干断层血管造影(OCTA)是一种快速、无创的成像方法，可以提供视网膜和脉络膜的实时血流信息。与传统的血管造影相比较，OCTA可以产生更详细、更高分辨率的血管图像，而不增加造影剂相关风险。年龄相关性黄斑变性(ARMD)是全球主要的老年性致盲眼病，OCTA能很好地显示脉络膜新生血管的影像，为ARMD的早期诊断及干预提供可能。本文将对OCTA在ARMD的相关图像特征及其诊断价值进行综述。

[Abstract]
Optical coherence tomography angiography(OCTA)is a rapid and non-invasive imaging tool, which can provide real-time flow imaging of retina and choroid. Compared with traditional angiography, OCTA can produce more detailed and high-resolution vascular images without increasing the risk due to contrast medium. Age-related macular degeneration(ARMD)is one of the major senile blinding eye diseases in the world, OCTA can well display the image of choroidal neovascularization and provide the possibility for early diagnosis and intervention. This review summarizes the OCTA image characteristics and clinical diagnostic value in patients with ARMD.
