If a pituitary tumour spreads to the optic nerve does it cause instant blindness?

Posted , 3 users are following.

My stepson now has a tumour for the second time which may have to be taken out soon.  If he decides not to have the operation and the tumour spreads to the optic nerve would blindness come gradually or instantly?

    Hi Victoria, had a single tumour removed and thankfully it hasn't come back, yet. The tumour will press on the optic nerve and impair vision.

    The vision loss is gradual, and in my case the effect was not permanent. Within a week or so my vision was back to normal, my visual fields returned and have been fine ever since.....just over 3 years now.

    So I don't believe vision loss is sudden or necessarily permanent, certainly not in my case.

      Hi esc4p3

      Thank you for replying and telling me your experience of visual loss.  That is what I wanted to know.

      I do hope that you do not have a recurrence of a tumour.

    HI Victoria,

    my brother had a tumor on his pituitary gland. It was left untreated for a year due to misdiagnosis and wrapped around the optic nerve and lost all peripheral vision an has double vision. He had 2 surgeries to remove the tumor. It has been 10 months since his surgeries and has not gained any vision back. This is something you don't want to wait on. he also lost all short term memory. The longer you wait the harder it will be for his recovery.

      Hi Joann

      I am so sorry that your brother was not diagnosed correctly and that he still cannot see nor remember things.  I shall pray for him.  My stepson is going to see the anaesthetist next week but has no date for the op yet.

      Thank you for replying.
