Optical coherence tomography angiography (OCTA) is a new technology of angiography which features multiple advantages over the traditional ones. It can provide a rapid and noninvasive approach to observing the vascular morphology and blood vessel density of the optic disc, peripapillary and macular area. Nonarteritic ischemic optic neuropathy (NAION) is an acute optic neuropathy characterized by a sudden, painless decrease in vision and a typical visual field defect. It has been widely accepted that the circulatory insufficiency of the optic nerve head (ONH) mainly supplied by the posterior ciliary arteries (PCA) results in ischemic damage. Relevant researches are necessary for exploring the pathogenesis, diagnosis and treatment of NAION, and this review summarizes the results of recent studies on application of OCTA in analyzing the blood flow in the optic and macular area in NAION patients. .
光学相干断层扫描血管造影（OCTA）是一种血管造影新技术，与传统技术相比具有多种优势。它能提供一种快速、无创的方法来观察视盘、视乳头周围和黄斑区的血管形态及血管密度。非动脉炎性缺血性视神经病变（NAION）是一种急性视神经病变，其特征为视力突然无痛性下降及典型的视野缺损。人们普遍认为，主要由睫状后动脉（PCA）供血的视神经乳头（ONH）循环不足会导致缺血性损伤。开展相关研究对于探索NAION的发病机制、诊断和治疗很有必要，本综述总结了近期关于OCTA在分析NAION患者视神经和黄斑区血流方面的研究结果。
