Abstract:

Optical coherence tomography angiography (OCTA) is a non-invasive imaging technology that can be used to assess the posterior segment of the eye by providing  three-dimensional image of the vessels, quantifying the retinal and choroidal blood flow, and obtaining corresponding structural parameters. The retinal vessel density(VD) of glaucoma was significantly lower than that of normal control. Quantitative analysis of optic disc and macular VD by OCTA was strongly correlated with the changes in the structure and function of glaucoma. Therefore, detecting abnormal blood flow in glaucoma using OCTA combined with clinical manifestations and other examination techniques  can provide a more reliable early diagnosis and disease assessment of glaucoma. （Int Rev Ophthalmol，2018,42：418-422）
