neuritis

pl. neuritides; inflammation of a nerve; also used to denote noninflammatory lesions of the peripheral nervous system. See also neuropathy.

There are many different forms of neuritis. Some increase or decrease the sensitivity of the body part served by the nerve; others produce paralysis; others cause pain and inflammation. The cases in which pain is the chief symptom are generally called neuralgia.

Neuritis and neuralgia affect the peripheral nerves, the nerves that link the brain and spinal cord with the muscles, skin, organs, and all other parts of the body. These nerves usually carry both sensory and motor fibers; hence both pain and some paralysis may result.

equine exudative optic neuritis

a cause of sudden blindness in old horses of unknown etiology but sometimes associated with trauma to the head. There are signs of acute inflammation with optic neuritis and later atrophy.

equine proliferative optic neuritis

an incidental unilateral finding in old horses of cauliflower-like mass attached to the optic disk; vision is not impaired.

experimental allergic neuritis (EAN)

an ascending polyneuritis produced experimentally by the administration of nerve tissue. The condition resembles guillain-barré syndrome, cauda equina neuritis in horses, and coonhound paralysis. Called also allergic, autoimmune neuritis.

interstitial neuritis

inflammation of the connective tissue of a nerve trunk.

multiple neuritis

neuritis affecting several nerves at once; polyneuritis.

optic neuritis

inflammation of the optic nerve, affecting the part of the nerve within the eyeball (neuropapillitis) or the part behind the eyeball (retrobulbar neuritis).

parenchymatous neuritis

neuritis affecting primarily the axons and the myelin of the peripheral nerves.

retrobulbar neuritis

optic neuritis affecting the part of the optic nerve behind the eyeball.

toxic neuritis

neuritis due to some poison.

traumatic neuritis

neuritis following and due to injury.
