A Common First Symptom of Multiple Sclerosis
Watch the video" c-nmssatomrichtext_nmssatomrichtext-host=""> Optic neuritis is caused by inflammation of the optic (vision) nerve. It usually occurs in one eye and may cause aching pain with eye movement, blurred vision, dim vision or loss of color vision.For people with optic neuritis, the color red may appear washed out or gray, vision may be lost completely in the affected eye, or a blurred or dim spot (scotoma) may occur in the center of the visual field, with peripheral vision unaffected. It is possible that after experiencing optic neuritis in one eye, you may experience it in the other eye at some time in the future — although this does not always occur.Optic neuritis with a loss of vision can be alarming, but in most cases your vision returns. Residual symptoms are possible, and you may notice dim or blurred vision if you are very fatigued or overheated. Rest and cooling generally help vision return.Treatment for optic neuritis includes high doses of corticosteroids, such as intravenous methylprednisolone or prednisone pills.

Normally, the muscles work in a coordinated way, but, when diplopia occurs, muscles on one side may be weak from nerve damage. This results in eye movements that are no longer coordinated. For people with diplopia, this may produce two side-by-side images or one image on top of another.Diplopia may be temporary or persistent and may resolve without treatment. When diplopia is a new symptom, it may be part of an MS relapse and a brief course of corticosteroids (anti-inflammatory medication) may be helpful. Patching one eye can also be useful for driving or when performing other tasks. Special eyeglass lenses known as prism lenses may be helpful for persistent diplopia.

Movement is usually rapid and can be up-and-down, side-to-side or rotating.Nystagmus may occur when looking straight ahead or when you move your eyes, making you feel like the world is moving. It may come and go or be persistent. Holding your head at an angle may reduce symptoms. Treatment for nystagmus is limited. Watch the video
