Venous occlusion of the fundus venosus generally refers to retinal vein obstruction, which can be controlled by medication as well as surgical treatment. 1. Drug treatment: there is no specific drug to treat this disease, the principle of treatment is to reduce intraocular pressure and treat blood clots. Patients can use streptokinase and other agents to reduce venous thrombosis in the fundus, or use aspirin and other anticoagulant drugs to improve symptoms. Patients can also be treated with anti-vascular endothelial growth factor drugs such as Ranibizumab and Compazine. 2. Surgery: For patients who are not well treated with medication or whose condition is more serious, laser surgery such as total retinal photocoagulation may be needed. It is recommended that patients with retinal vein occlusion should seek medical treatment as soon as possible, and medications should be used according to the doctor’s instructions in order to avoid adverse effects on vision.
