Loss of vision
A
optic nerve
B
olfactory nerve
C
abducting
D
oculomotor
Explanation: 

Detailed explanation-1: -Optic neuritis occurs when swelling (inflammation) damages the optic nerve-a bundle of nerve fibers that transmits visual information from your eye to your brain. Common symptoms of optic neuritis include pain with eye movement and temporary vision loss in one eye.

Detailed explanation-2: -Optic nerve atrophy causes vision to dim and reduces the field of vision. The ability to see fine detail will also be lost.

Detailed explanation-3: -There are no effective treatments to regenerate nerve cells or to restore connections between the eye and brain once the optic nerve is lost. This is a major barrier in the field and one that must be overcome, given the substantial number of patients suffering from optic neuropathy-associated blindness.

Detailed explanation-4: -Optic neuritis usually improves on its own. In some cases, steroid medications are used to reduce inflammation in the optic nerve. Possible side effects from steroid treatment include weight gain, mood changes, facial flushing, stomach upset and insomnia. Steroid treatment is usually given by vein (intravenously).
