Vision loss - brain tumour- is it permanent?

[Teaplease29]

Hi everyone,

Can anyone tell me if loss of vision due to pressure on optic nerve is permanent or can it be temp?

Thank you x

In my husband’s case, it was permanent. The optic nerve was damaged and couldn’t be repaired.

I think it depends on the type of vision loss. I have a pituitary adenoma which if it touches the chasm can affect peripheral vision. If that should happen surgery to remove it would rectify the problem. So I have to have regular vision field tests and MRI scan to monitor it.
