Nystagmus is a potential visual symptom of multiple sclerosis. Nystagmus is the involuntary movement of the eyes, which can be from side to side, up and down, or in a rotary manner. This sometimes goes unnoticed by the person with MS but can be clearly seen by an observer. If it is more persistent, nystagmus may contribute to dizziness or nausea.
Nystagmus can be a difficult symptom to treat. Occasionally drug therapy with gabapentin or memantine may help.
