Is there any way of optic nerve replacement???

Question

This is for all the doctors, eye surgeons, opthalmologists or neurologists, and even for the other helpful people...
my bro had optic nerve tumor(called glioma)... his nerve had converted into a tumor and had to be operated and taken out coz it was growing and moving towards the brain... now his optic nerve of right eye is removed i.e. he is visionless from that eye....
i want to know whther anyone knows any way to replace or regenerate optic nerve .. coz we really are upset about him being unable to see from his one eye....
as u know, we get only 2D images from one eye and to get 3D images, having two working eyes are must...
if anyone of u knows any way to get him his vision back then do reply to this one..
thanku

Answer 1

No, I'm sorry, there's neither currently nor in immediate prospect any way to regenerate optic nerves.
The techniques being attempted to "bridge" spinal injuries are dealing with far too few impulses to correlate to optic nerve replacement.

However...
" 2D images from one eye and to get 3D images, having two working eyes are must..."
is both true and misleading.
Absence of stereopsis, true 3D vision, does not mean no ability to judge distances.
Stereopsis only works out to 20-40 ft (textbooks vary)
Beyond that *everyone* is using the many other clues, cues, to depth. Beyond 40ft your brother is at no disadvantage.
These mechanisms are used by all of us including effectively one-eyed persons (about 1 in 30 of the population) at closer ranges too:
relative size, perspective, aerial perspective, texture, superposition, parallax... They all help, and work with one eye.
Only a few specific activities *require* binocular vision, though some, naturally, are easier with it.

Answer 3

Your bro should have a baby. That baby will have intact optic nerves thus replacing his.
