Therapy
Congenital
Congenital nystagmus has traditionally been viewed as non-treatable, but
medications have been discovered in recent years that show promise in some
patients. In 1980, researchers discovered that a drug called baclofen could
effectively stop periodic alternating nystagmus. Subsequently, gabapentin, an
anticonvulsant, was found to cause improvement in about half the patients who
received it to relieve symptoms of nystagmus. Other drugs found to be effective
against nystagmus in some patients include memantine, levetiracetam,
3,4-diaminopyridine, 4-aminopyridine, and acetazolamide. Several therapeutic
approaches, such as contact lenses, drugs, surgery, and low vision
rehabilitation can also be used in order to improve visual function.
Acquired
Pathological acquired nystagmus is mostly a temporary condition and stops
spontaneously. When it is secondary to a neurological disorder, this must be
treated accordingly.
