Indian Journal of Ophthalmology. 2009 Nov; 57(6): 463-464.http://imsear.searo.who.int/handle/123456789/136001Acquired disruption of motor fusion is a rare condition characterized by intractable diplopia. Management of these patients is extremely difficult. Prisms in any combination or even surgery may not help relieve their symptoms. We describe a longstanding case of acquired motor fusion disruption which was managed successfully with botulinum toxin injection.enAcquired motor fusion deficiencybotulinum toxinAdultBotulinum Toxins, Type A --administration & dosageDepth Perception --physiologyDiplopia --complicationsDiplopia --drug therapyDiplopia --physiopathologyElectromyographyEye Movements --drug effectsEye Movements --physiologyFemaleHumansInjections, IntramuscularNeuromuscular Agents --administration & dosageOcular Motility Disorders --complicationsOcular Motility Disorders --drug therapyOcular Motility Disorders --physiopathologyOculomotor MusclesStrabismus --complicationsStrabismus --drug therapyStrabismus --physiopathologyVisual AcuityArticle
