	Optic neuritis - Wikipedia, the free encyclopedia
		Optic [[neuritis](or retrobulbar neuritis) is the inflammation of the optic nerve that may cause a complete or partial loss of vision.
		The optic nerve comprises axons that emerge from the retina of the eye and carry visual information to the primary visual nuclei, most of which is relayed to the occipital cortex of the brain to be processed into vision.
		Optic neuritis is generally diagnosed and comanaged by neurologists and ophthalmologists.

		In optic neuritis and other autoimmune diseases, the body's immune system has decided that otherwise normal tissues are foreign and therefore have attacked it.
		In some cases of optic neuritis there may be more extensive involvement including the other optic nerve, the chiasm (where the two optic nerves come together), or other tissues in the brain.
		The second most common symptom associated with optic neuritis is discomfort in or around the eye often made worse by movement of the eye.

		Optic neuritis, or inflammation of the optic nerve, is a common manifestation of MS.
		The anterior end of the optic nerve (called the optic nerve head or optic disc), visible on ophthalmic examination, appears normal in most eyes with optic neuritis but is swollen in approximately one- third of the cases.
		When optic neuritis occurs in a patient with clinically definite MS, the optic neuritis should be considered as a clinical relapsing or remitting MS event; in such cases, IV steroid treatment and repeat MRI may be considered, and the patient's MS treatment should be reassessed.
