What Is Optic Neuritis?
9. Does Optic Neuritis Cause MS?
Individuals who get optic neuritis are at higher risk of contracting multiple sclerosis. Individuals who have one episode of ON are 50% more likely to develop MS over the course of their lifetimes. The risk increases for those who have lesions on their brain, which makes an MRI especially important in diagnosing ON.
People who are at high risk of getting MS are often prescribed medication to reduce the likelihood the disease develops. If you have two or more lesions on the brain, your doctor may prescribe these medications to help delay or prevent the onset of MS.
