Improvement of acquired pendular nystagmus by gabapentin: case report.Bull Soc Belge Ophtalmol. 2001BS
Acquired Pendular Nystagmus (APN) may cause distressing visual symptoms in patients who are already suffering a severe general disease. Averbuch-Heller et al. conducted the first double-blind controlled study on treatment for APN. They showed that gabapentin substantially reduces pendular nystagmus and significantly increases visual acuity in the majority of patients. We present a patient with APN due to multiple sclerosis who suffered severe oscillopsy and reduction of visual acuity and who substantially benefited from a trial treatment with this agent.
