blind by sickness?

Question

if someone get seriously ill, and lost the eye sight, can that kind of illness can be gone? can get the eye sight back?

she got fever for long time... and as a result she lost the light of eyes, and now she cannot see anymore, can that kind of blindness be gone?

Answer 1

Yes. In certain cases, and in certain cases only, even complete loss of vision CAN be recoverable.

It will depend very much on the disease, how long it has been present, and how successful the treatment for it has been.

With passive pressure on the optic nerve, found with raised intracranial pressure (including in meningitis), and with pituitary tumours, vison MAY return quite dramatically.

After loss of vision related to conditions such as temporal arteritis, recovery has been noted.

None of the above should be taken as a promise. In many cases of severe disease the retina, optic nerve or visual processing regions in the brain sustain damage from which they cannot recover, or recover only to a limited extent.
