What can I do if the optic nerve is damaged?

Question from a reader: My son this year had a brain tumor removed, unfortunately it had damaged the optic nerve and left him partially sighted in one eye and blind in the other. In the six months since the operation his sight in the “good eye” has improved but nothing in the blind eye. Is there anything we could do about his blindness in that eye treatment or operation?
Dear Parent:
It is great news that sight in the "good eye" has improved. Unfortunately, if there was damage to the optic nerve of the other eye, then there is nothing available to help your son with the blind eye.

Depending on how much vision remains in the "good eye", your son may benefit from a low vision specialist evaluation who is an eye doctor specializing in patients with impaired vision. There are computers and aides that may benefit your son.

As a parent you would also need to ensure what tasks the Low vision aids are for, when to use them, and take personal interest in them.

Children often don't like using LVA's as this makes them appear different from their peers, they will need a lot of encouragement on this issue.You can also decorate them with stickers and coloured tapes.

We do not know the tumour that was removed, in case it had a hereditary basis, then genetic counselling would be advisable.

Also, one of my colleagues said, "I have seen glaucomatous cupping and visual field defects reverse in young patients with glaucoma. So, in certain situations, optic nerve damage can be reversed."

In the situation above, however, because vision has not returned for six months, it is unlikely for the damage to reverse.
