[4] [5] [2]Many patients with optic neuritis may lose some of their color vision in the affected eye (especially red), with colors appearing subtly washed out compared to the other eye.
Optic neuritis, when combined with the presence of multiple demyelinating white matter brain lesions on MRI, is suspicious for multiple sclerosis. Several causes and clinical courses are possible for the optic neuritis. It can be classified in: Single isolated optic neuritis (SION) relapsing isolated optic neuritis (RION)
The optic chiasm, or optic chiasma is the part of the brain where both optic nerves cross. It is located at the bottom of the brain immediately inferior to the hypothalamus. [7] Signs and symptoms associated with optic chiasm lesions are also known as chiasmal syndrome.
It presents with visual loss and signs of optic nerve dysfunction, such as loss of color vision, afferent pupil defect, and sometimes abnormalities of the optic disc. The clinical features of AON can be variable and present in several unilateral or bilateral forms: Acute anterior or retrobulbar optic neuritis sometimes associated with pain.
The optic disc is where the axons from the retinal ganglion cells collect into the optic nerve. The optic nerve is the bundle of axons that carry the visual signals from the eye to the brain. This optic nerve must penetrate through the wall of the eye, and the hole to accommodate this is usually 20-30% larger than the nerve diameter.
Optic neuritis is also commonly associated with periocular pain, phosphenes, and other visual disturbances. Treatment of acute optic neuritis involves corticosteroids, plasmapheresis, and IV immunoglobulins in additions to disease modifying immunotherapies to manage the underlying neuropathology associated with the acute inflammatory episode.
