There is no definite treatment for central retinal vein occlusion at present, but it can be treated by etiology or symptomatic treatment, which may include traditional Chinese medicine to activate blood circulation and remove blood stasis, fibrinolytic preparation, prostaglandin E1 lipid microsphere carrier preparation, blood-thinning therapy, laser therapy, corticosteroid therapy, surgery, and so on. In the early stage of the disease, traditional Chinese medicine can be used to activate blood circulation and remove blood stasis, dilate blood vessels and inhibit platelet aggregation, such as thrombolytic injection, Panax ginseng tablets, Dan Shen tablets and so on. Fibrinolytic preparations are suitable for patients with increased fibrinogen, such as urokinase intravenous drip, pancreatic kinin-releasing enzyme tablets and so on. Prostaglandin E1 lipid microsphere carrier preparation can inhibit platelet aggregation and dilate blood vessels. Hemodilution therapy reduces blood viscosity to improve microcirculation. Laser therapy reduces capillary leakage and retinal edema. Corticosteroid therapy can reduce macular edema, such as intravitreal injection of tretinoin. Vitrectomy is feasible if accompanied by vitreous hemorrhage. If central retinal vein obstruction is found, it is necessary to go to the hospital in time for relevant examinations, and formulate the treatment according to the examination results and the doctor’s recommendations.
