Risk factors for central retinal artery obstruction include cardiovascular disease, inflammatory vascular disease, risky sports, radiation therapy, anesthesia, etc. It is recommended that people with this condition should consult a doctor promptly when they develop visual dysfunction. 1. Cardiovascular diseases: Atherosclerosis, hypertension and other diseases can easily lead to thickening and narrowing of the arterial wall of the central retinal artery and arterial spasm. 2. Inflammatory vascular disease: Thrombophlebitis, temporal arteritis and other diseases may involve the central retinal artery and lead to vascular embolism. 3. Engaging in dangerous sports: Basketball, volleyball, soccer and other sports can easily lead to eye trauma, thus increasing intraocular pressure and compression of the eyeball, resulting in blockage of the central retinal artery. 4. Radiotherapy: Some people undergoing head and neck radiotherapy may have eye injuries. 5. Anesthesia: Ocular anesthesia and surgery requiring prone anesthesia may lead to increased intraocular pressure, which may result in the development of the disease. Central retinal artery occlusion requires prompt medical attention to identify and treat the cause.
