For instance, you could experience fatigue or balance problems alongside optic neuritis. This can occur if you have inflammation in different parts of your central nervous system.
See your healthcare provider right away if you have eye pain, experience loss of vision, or see flashing lights. Fast action can help prevent permanent vision loss or other serious health problems. Be sure to get medical attention if you notice new symptoms, such as a change in how well you can see. Optic neuritis symptoms generally improve in 80 percent of patients over a few weeks according to the Cleveland Clinic. Your prognosis for improved long-term vision is better than if you do have MS, however.
Having both optic neuritis and MS may make you more likely to experience recurring symptoms of optic neuritis. NMO is a rare autoimmune disorder that can lead to vision loss and paralysis.
Finding the right specialist can help you manage symptoms and prevent…. Getting proper, prompt NMO treatment can help prevent disease activity recurrence that can have devastating, irreversible effects.
Learn about…. Neuromyelitis optica NMO and multiple sclerosis MS are both immune system disorders that affect the nerves. Compare NMO vs. Sudden vision loss that occurs on awakening is more likely caused by ischemia than by ON. Gradual vision loss progressing for a month or more is more likely to describe a compressive lesion. Ask the patient whether she has ever experienced symptoms of MS such as fatigue, Uhthoff symptom, L'Hermitte's sign tingling at the base of the spine when flexing the neck , weakness, pain, tingling or numbness in the arms and legs, incoordination and bowel and urination difficulties.
Question the patient about symptoms of other autoimmune disease or other causes of ON such as sarcoidosis, lupus erythematosus or recent infections. If the history is negative, blood tests need not be ordered. Measure visual acuity and color vision. Record the visual field on a Humphrey threshold test including foveal sensitivity. Check for the presence of relative afferent pupillary defect and quantify the defect with neutral density filters, if possible.
This will enable determination at a follow-up visit of whether the patient's vision has improved. You'll want to check for ocular motility abnormalities common in MS, such as internuclear ophthalmoplegia or nystagmus. Have your patient undergo MRI of brain and orbits with and without gadolinium. Follow-Up If the neuro-ophthalmic patient has one or more lesions on her MRI, she has a much higher risk for developing MS than someone who has no lesions.
A three-day course of Solumedrol can be administered to speed recovery and to decrease the risk of clinically definite MS over the next two years.
The protocol for Solumedrol treatment has been variously modified without scientific verification of efficacy. Without knowledge of the critical parameters of steroid dosage, many practitioners have tinkered with the Solumedrol protocol used by the ONTT.
Specifically, since IV steroids are now usually administered on an outpatient basis, Solumedrol 1 g per day for three or four days is commonly given instead of divided doses, and the oral taper is frequently omitted. Controlled trials have not been done to establish the efficacy of these modified protocols. The reasons for the poor outcome of oral prednisone-treated patients in the ONTT remain hypothetical.
Oral prednisone, however, is still contraindicated. Partnership with Neurology The patient with typical, isolated, monosymptomatic ON should be referred promptly to a neurologist who can begin immunomodulatory medication. The results of the neuro-ophthalmic exam should accompany the patient to the neurologic consultation. The neurologist relies on the ophthalmologist to accurately diagnose ON and to distinguish demyelinating ON from other optic neuropathies or retinal conditions that have similar symptoms.
The neurologist will want neuro-ophthalmic or ophthalmic follow-up including an exam six to 12 weeks after onset to assess the degree of recovery from the acute ON. Periodic examinations after that will assess the stability or progression of any visual field defects. Physicians have reason to be more hopeful and optimistic about the prognosis for MS presenting as ON and the long-term prognosis of MS.
We have new information about the levels of risk for developing MS after neurologic events, and we have immune-modulating therapies. Ophthalmologists should sharpen diagnostic and decision-making skills to discern which patients will benefit most from these therapies.

Optic Neuritis Study Group. The clinical profile of acute optic neuritis: experience of the Optic Neuritis Treatment Trial. Arch Ophthalmol ; A randomized, controlled trial of corticosteroids in the treatment of acute optic neuritis. N Engl J Med ; About 50 percent of people who have MS experience a bout of optic neuritis at least once, according to The Transverse Myelitis Association.
As with MS itself, women are more susceptible to optic neuritis than men. Recurrences of optic neuritis are not uncommon, but why it recurs in some people and not others is not known — and when it might recur for any one person is unpredictable. Marni Blake Ellis, 33, of Brooklyn, New York, has had three episodes of optic neuritis in the plus years since she was diagnosed with MS. It was her first MS symptom , back in Ellis hasn't seen a pattern to her bouts of optic neuritis.
But she suspects that it, like her other symptoms, may be related to stress. Optic neuritis is a prominent symptom of neuromyelitis optica spectrum disorder NMOSD , an inflammatory disorder of the central nervous system. People with optic neuritis who have demyelination spots, plaques or lesions on their brain MRI, have a much higher risk of developing MS, possibly as high as 80 percent.
People with optic neuritis usually notice blurry vision or hazy vision affecting one eye. Less commonly, both eyes can be affected at the same time. Often the center of vision is involved, but any part of the visual field may be affected. In optic neuritis, the blurring of vision may gradually worsen over the course of a week or so. Afterward, there is usually a gradual recovery of vision, occurring over four to six weeks, though additional recovery may occur over six to twelve months or longer.
Typically 1, mg of IV methylprednisolone are infused daily for three to five days.
