PURPOSE: To evaluate the use of, botulinum toxin A in the treatment of congenital nystagmus in children. MATERIAL AND METHODS: 32 children with nystagmus and esotropia (group I), nystagmus and exotropia (group II) and horizontal and vertical nystagmus (group III). Intramuscular injections of botulinum toxin A was performed in all treated children. RESULTS: In group I the amplitude of nystagmus diminished of 50%, in group II of 42.9% and in group III of 28,6%. Near and distant visual acuity improved in all treated children. CONCLUSIONS: Treatment of congenital nystagmus with botulinum toxin A causes reduction of the amplitude of nystagmus, partial improvement of visual acuity and improvement of anomalous head posture.
