A disorder characterized by inflammation of the optic nerve. Causes include autoimmune disorders, infections, toxins, drugs, and multiple sclerosis. It may manifest with acute loss of vision and pain.

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 second cranial nerve or optic nerve; commonly associated conditions include autoimmune disorders such as multiple sclerosis, infections, and granulomatous diseases.

Optic neuritis is inflammation of the optic nerve. Symptoms are usually unilateral, with eye pain and partial or complete vision loss. Diagnosis is primarily clinical. Treatment is directed at the underlying condition; most cases resolve spontaneously.

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.

Optic neuritis is inflammation of the optic nerve, the nerve that carries the visual signal from the eye to the brain. The condition may cause sudden, reduced vision in the affected eye(s). While the cause of optic neuritis is unknown, it has been associated with autoimmune diseases, infections, multiple sclerosis, drug toxicity and...

Optic neuritis (ON) represents inflammation of the optic nerve. By far the most common form is idiopathic ON, which is a primary demyelinating disease occurring in isolation or as part of multiple sclerosis (MS). When in isolation, primary demyelinating ON is considered a forme fruste of MS. ON manifests as the subacute or acute onset of...

Optic neuritis, inflammation of the optic nerve (the second cranial nerve). The inflammation causes a fairly rapid loss of vision in the affected eye, a new blind spot (a scotoma, usually in or near the centre of the visual field), pain in the eyeball (often occurring with eye movement), abnormal...
