Subarachnoid hemorrhage does not usually cause bleeding in the fundus of the eye, but more severe subarachnoid hemorrhages may also cause intracranial hypertension, which can lead to bleeding in the fundus of the eye. Subarachnoid hemorrhage is caused by a rupture of a blood vessel at the base or surface of the brain that causes blood to enter the subarachnoid space. Major complications include rebleeding, cerebral vasospasm, and hydrocephalus. Fundus hemorrhage, on the other hand, may be associated with a variety of factors, including high blood pressure, ocular inflammation, and atherosclerosis. Generally, subarachnoid hemorrhage does not cause fundus hemorrhage, but when subarachnoid hemorrhage is very severe, compression of the brain tissue leads to increased intracranial pressure, which may also lead to fundus hemorrhage in patients. If subarachnoid hemorrhage is not treated in time, it may affect the patient’s life. Patients with subarachnoid hemorrhage are advised to seek prompt medical attention to evaluate their condition and follow medical advice.
