Loss of vision after craniotomy may be due to damage to the optic nerve or optic bundle. Diseases that cause nerve damage generally include: acute intracranial hemorrhage, intracranial hematoma, and all kinds of intracranial space-occupying lesions, such as arteriovenous malformations, aneurysms and so on.
1. Acute intracranial hemorrhage and intracranial hematoma: the hematoma compresses the brain tissue and causes cerebral edema, which makes the blood and oxygen supply to the brain nerves and brain cells insufficient, which leads to the damage of the nerve function, and the patient may suffer from loss of vision, which is not caused by the craniotomy itself.
2. All kinds of intracranial occupying lesions, such as arteriovenous malformation, aneurysm, etc., due to the long-term compression of the tumor, can lead to ischemia and hypoxia necrosis of cerebral nerves, which may lead to vision loss. In addition, in the process of tumor resection and stripping, it is also easy to produce nerve damage, so that vision loss.
It is recommended that patients with vision loss should go to the hospital in time to find out the cause of the disease and under the guidance of the doctor, so as not to delay the condition.
