-
Inflammation of the optic nerve. Commonly associated conditions include autoimmune disorders such as MULTIPLE SCLEROSIS, infections, and granulomatous diseases. Clinical features include retro-orbital pain that is aggravated by eye movement, loss of color vision, and contrast sensitivity that may progress to severe visual loss, an afferent pupillary defect (Marcus-Gunn pupil), and in some instances optic disc hyperemia and swelling. Inflammation may occur in the portion of the nerve within the globe (neuropapillitis or anterior optic neuritis) or the portion behind the globe (retrobulbar neuritis or posterior optic neuritis).

Inflammation of the optic nerve, either of the optic disk alone or of the trunk of the nerve; characterized by an infiltration of the connective tissue framework with the products of inflammation and by the proliferation of the connective tissue cells. Vision is almost always seriously affected, owing to the presence of a scotoma. [Gr.]
