Optic neuritis and multiple sclerosis

Optic neuritis causes visual loss or scotomas in one or both eyes and, in 75% of cases, may be part of a more diffuse demyelinating process (MS). Most individuals suffering from this disease improve spontaneously; ACTH therapy, however, may be helpful in clearing the symptoms faster if the vision is markedly involved or not improving. Every patient with optic neuritis should have a detailed neurological examination to determine whether this condition represents a presentation of MS.
