Nystagmus: an update on treatment in adults

Recent developments in the treatment of nystagmus in adults have changed the traditional approach to such illnesses as benign paroxysmal positional vertigo, vestibular neuritis, Meniere's disease, superior canal dehiscence syndrome, vestibular paroxysmia, superior oblique myokymia, downbeat/upbeat nystagmus and acquired pendular nystagmus, as well as periodic alternating nystagmus. Treatments reported to suppress nystagmus, with tolerable side effects, are now available for some of these syndromes. Due to the absence of large controlled studies, however, treatment recommendations rest only on class C evidence.
