Postoperative frontal-parietal light hemorrhage generally refers to postoperative frontal-parietal hemorrhage, postoperative patients with blurred vision may be due to increased intracranial pressure, optic nerve damage, etc. Patients follow the doctor’s instructions to use dehydrating drugs, nutritive neurotoxicity drugs for treatment to improve their vision. Hemorrhage in the frontoparietal area may be caused by intracranial arteriovenous malformation, vascular disease and other factors, which may lead to physical and speech disorders. After surgery to remove the accumulated blood, patients may experience increased intracranial pressure, which leads to edema and impaired function of the optic nerve, so it may cause patients to experience blurred vision. Patients can be treated by taking medicines that nourish the nerves under the doctor’s guidance, such as methylcobalamin tablets and vitamin B1 tablets to repair the damaged optic nerve tissues. At the same time, patients can also be injected intravenously with glucocorticosteroids and dehydrating agents such as mannitol to reduce intracranial pressure and relieve optic nerve edema, thus improving the patient’s vision. It is recommended that postoperative patients with frontal-parietal hemorrhage should follow the doctor’s instructions, have regular checkups, and consult the doctor promptly when discomfort occurs.
