Repeated bilateral retrobulbar injection of botulinum toxin in a blind patient with retinitis pigmentosa and incapacitating nystagmus.
Pronounced visual loss can lead to nystagmus, provoking oscillopsia and distressing ocular sensations. The treatment of acquired nystagmus remains difficult and various therapeutic options are attempted with limited results. We report the case of a man with acquired nystagmus and excessive ocular discomfort, successfully treated with repeated retrobulbar injections with botulinum toxin.
