青光眼是一种神经退行性疾病，其特征性改变为视盘的凹陷性萎缩和视野的特征性缺损。目前青光眼的诊断和评价主要应用眼底照相、光相干断层扫描和视野检查。血流动力学改变在青光眼视神经损害的病理生理学机制中占有重要作用。以往对视盘的血流评估都是针对大血管，而对于微血管的血流定量评估一直缺少很好的评估设备。光相干断层扫描血管成像技术(OCTA)可实现对视网膜及脉络膜血流的量化，为青光眼视神经损害的评价提供了新的手段和指标。本文对应用OCTA技术测量视盘和黄斑区的血管密度在青光眼诊断和进展评估中的研究及血流参数与视神经纤维层和筛板等结构参数和视野参数的一致性等方面的研究进展进行综述，评价血流参数在青光眼损害评估中的作用。“,”Glaucoma is a neurodegenerative disease, which is characterized by a concave atrophy of the optic disc and a characteristic defect of the visual field.The current diagnosis and evaluation of glaucoma are mainly based on fundus photography, optical coherence tomography and visual field examination.Hemodynamic changes play an important role in the pathophysiology of glaucomatous optic nerve damage, however, blood flow evaluation of the optic disc has been directed to large vessels in the past, and there has been no good evaluation equipment for quantitative evaluation of blood flow in microvessels.Optical coherence tomography angiography quantifies blood flow in the retina and choroid, which provides a new method and index for the evaluation of glaucomatous optic nerve damage.In this paper, the application of optical coherence tomography angiography in the measurement of blood vessel density in the optic disc and macular region in the diagnosis and progress assessment of glaucoma, and the consistency of blood flow parameters with structural parameters such as the optic nerve fiber layer and sieve plate and visual field parameters, etc.were reviewed to evaluate the value of blood flow parameters in predicting and assessing glaucomatous damage.
