Can vision recover after surgery for a meningioma compressing the optic nerve?

In general, whether vision can be restored after surgery for optic nerve compression caused by meningioma depends on the specific condition. If the meningioma is small and has compressed the nerve for a short period, vision recovery is possible. However, if the tumor is large and has exerted prolonged pressure, the likelihood of recovery is significantly reduced. If any discomfort occurs, prompt medical attention is recommended. The detailed analysis is as follows:

When the meningioma is small, its compressive effect on the optic nerve is relatively limited, resulting in milder nerve damage. Additionally, if the duration of compression is short and the optic nerve has not yet undergone severe structural changes or functional loss, the nerve may gradually regain normal function after surgical removal of the tumor and relief of compression, potentially leading to improvement or recovery of vision.

A larger meningioma may cause prolonged and severe compression of the optic nerve. Such chronic pressure can lead to structural changes in the optic nerve, such as nerve fiber atrophy or rupture, resulting in significant functional impairment. In these cases, even after surgical removal of the tumor and decompression, the optic nerve may have already sustained irreversible damage, greatly reducing the possibility of vision recovery.

To help prevent intracranial lesions such as meningiomas, it is advisable to maintain a healthy lifestyle, including a balanced diet, moderate exercise, and adequate sleep, to strengthen the body's immune system.
