The difference between retinal vasculitis and venous obstruction is mainly manifested in the etiology, prevalent population, and treatment methods. 1. Retinal vasculitis is mainly due to inflammatory stimulation of retinal blood vessels, manifested as vasodilatation, leakage, rupture, causing hemorrhage and edema in the fundus, which is mostly related to systemic immune diseases. It is most often associated with systemic immune diseases. It occurs in young people. The main treatment is targeted anti-inflammatory therapy, and glucocorticoids such as dexamethasone are chosen. 2. Retinal vein obstruction is mainly due to hypertension, diabetes mellitus, hyperlipidemia and other causes of intravascular embolism, which leads to retinal vein obstruction, and retinal veins are tortuous and dilated during the attack. It occurs in middle-aged and elderly people. Treatment is with thrombolytic drugs such as urokinase, anticoagulants such as aspirin, and drugs to improve microcirculation such as ginkgo biloba. For the difference between retinal vasculitis and venous occlusion, it is recommended to go to the hospital in time to check the fundus blood vessels and clarify the cause of treatment.
