Nutritional optic neuropathy (aka deficiency optic neuropathy) is a dysfunction of the optic nerve resulting from improper dietary content of certain nutrients essential for normal functioning of the nerve fibers. Progression of the neuropathy is associated with optic nerve atrophy, manifesting as complete disc pallor.
People also ask, is nutritional optic neuropathy reversible?
In both toxic and nutritional neuropathy, vision generally recovers to normal over several days to weeks, though it may take months for full restoration and there is always the risk of permanent vision loss. Visual acuity usually recovers before color vision.
Beside above, can b12 cause optic neuritis? Optic neuropathy secondary to vitamin B12 deficiency occurs in less than 1% of B12 deficient patients. It results in progressive, bilateral, painless vision loss that is often associated with reduced color vision and central or cecocentral scotomas.
In this way, what is traumatic optic neuropathy?
Traumatic optic neuropathy (TON) refers to an acute injury of the optic nerve secondary to trauma. An indirect injury to the optic nerve typically occurs from the transmission of forces to the optic canal from blunt head trauma.
What medications can cause optic nerve damage?
Causes of toxic optic neuropathy include chemicals and drugs, such as methanol, ethylene glycol, ethambutol, isoniazid, digitalis, cimetidine, vincristine, cyclosporine, toluene, and amiodarone.
