Optic neuritis

Other Names:
Inflammation of optic nerve

Optic neuritis describes any condition that causes inflammation of the optic nerve; it may be associated with demyelinating diseases, or infectious or inflammatory processes.

It is also known as optic papillitis (when the head of the optic nerve is involved), neuroretinitis (when there is a combined involvement of the optic disc and surrounding retina in the macular area) and retrobulbar neuritis (when the posterior part of the nerve is involved). Prelaminar optic neuritis describes involvement of the non-myelinated axons in the retina.


Chronic alcohol abuse may produce problems in the optic nerve, called alcoholic optic neuritis. The main causes are vitamin B1 deficiency, and in some cases, zinc deficiency or raised lead levels.
