Fundus hemorrhage is not a precursor to cerebral infarction. Fundus hemorrhage can be divided into local etiology and systemic etiology.
1. Local etiology: it refers to the lesion of fundus itself, which is often caused by vascular occlusion and rupture and bleeding due to venous obstruction above the retina; or vascular rupture and bleeding due to inflammation of retinal blood vessels; and rupture of hemangiomas on the retina can also lead to hemorrhage in the fundus.
2. Systemic etiology: it refers to the long-term damage to blood vessels caused by diabetes mellitus, hypertension, chronic kidney disease and chronic vascular diseases, which leads to hemorrhage in the fundus.
Cerebral infarction refers to various cerebrovascular lesions causing blood supply obstruction in the brain, which ultimately leads to vascular occlusion and cerebral functional impairment. It is mostly seen in the elderly with risk factors of cerebrovascular diseases such as hypertension and diabetes.
Fundus hemorrhage and cerebral infarction can be caused by the same reason, such as high blood pressure, diabetes, etc., but it cannot be directly said that fundus hemorrhage is the precursor of cerebral infarction.
If fundus hemorrhage occurs, you should go to the hospital in time for treatment.
