Aged between 40 and 70 years old; 3. Subjects who fully understand the project and voluntarily sign the informed consent; Western medicine diagnostic criteria; (1) Sudden vision loss or black shadows in front of the eyes; (2) Dilated and tortuous retinal veins in the fundus, hemorrhage and edema on the surface of the affected veins; (3) Fundus fluorescein angiography: retinal vein filling time is delayed, capillary leakage, and no perfusion area is visible; (4) OCT examination showed macular edema, and the thickness of the fovea was more than 300um. TCM diagnostic criteria: Main symptoms: (1) decreased vision; (2) retinal hemorrhage, edema, exudation, and venous filling.
