Medical treatment of nystagmus is a relatively new venture in neuro-ophthalmology. Theoretically, the goal is inhibition of the abnormal movement by manipulating neurotransmitters or their agonists. The primary inhibitory neurotransmitters in the ocular motor pathways are GABA and glycine. GABA agonists that have been used with some success include clonazepam, baclofen, valproic acid, and isoniazid. Anticholinergic agents also have been tried but do not appear to be as effective. A potentially useful tool in the future may be retro-orbital injections of botulinum toxin. The major drawback of this treatment is the need for repeated injections every 4 to 20 weeks.
