Autoimmune optic neuropathy Isolated autoimmune optic neuropathy is different than the typical MS variant in that is less likely to have pain as a distinguishing feature, more often to have bilateral vision loss, and more likely to cause progressively worsening vision loss.
The typical immunomodulatory therapy used in MS has been associated with worse outcomes in the NMO variant 8, Dooley MC, Foroozan R.
Pathogenesis The precise pathogenesis is uncertain, but is believed to involve a delayed type IV hypersensitivity reaction involving activation of peripheral T-lymphocytes by an inflammatory process. The study concluded that patients with acute optic neuritis could be given the options of no treatment or IV methylprednisolone followed by oral prednisone. Skin biopsies will show IgG antibodies in the collagenous matrix and around blood vessels 7, Ischemic optic neuropathy ION Ischemic optic neuropathy ION could be mistaken for the MS variant because it commonly presents with unilateral vision loss and disc swelling.
