Can medical sciences treat a case of OPTIC NERVES not responding, and blindness therefore?

This 50 year old uncle of mine, is completely blind because of the typhoid he had , when he was 1 year old. He has underwent 3 surgeries of the brain when he was around 3 to about 7 years old , he has been treated by the best doctor of asia.
THEY COULDNT RESTORE HIS VISION SAYING ~~~THE OPTIC NERVES WONT RESPOND TO ANY THING FORMED ON THE RETINA. This was quite a long time back, with the advancements of medical science, these days, i would like to know IS THERE ANY WAY THIS 50 yr. OLD MAN CAN SEE THE WORLD?
He's a great man, has struggled for a career, has a fine govt. job of teaching now, plus a nice loving wife and 2 children.

I only want to know if such a case of optice nerves not responding be treated.
Thankyou for any help!

I have a brother who is blind. Due to optic nerve damage. From what we have been told. There is nothing medical that can be done. However nerves can, and have been known to rejuvenate on their own.

Dear CJ,
It would be good if you take him to an eye doctor (Optometrist/Ophthalmologist) and get him checked there, It is really difficult to say whether your uncle's vision can be restored or not sitting here and not knowing what exactly the condition is.
Get his VEP (Visiually evoked Potential) and VER ( Visual evoked response) tests done first.
