PURPOSE: The significance of botulinum toxin to ophthalmologists is twofold. Botulism, a medical emergency, frequently presents with ocular findings including blurred vision, diplopia, ptosis, and photophobia as a result of the neurotoxin produced by Clostridium botulinum. However, botulinum toxins also have therapeutic uses for medical conditions including strabismus. The safety and efficacy of Botulinum toxin A in patients with a history of botulism has not been reported.
OBSERVATIONS: We report a 9-week-old infant, diagnosed with type B toxin positive infant botulism treated with human botulism immune globulin, who developed a large angle exotropia. The infant was treated with intramuscular injections of botulinum toxin A to the extraocular muscles resulting in a favorable initial response but ultimately required strabismus surgery. Clinical manifestations and management of botulism are reviewed and botulinum toxin in the treatment of pediatric strabismus is discussed.
CONCLUSIONS AND IMPORTANCE: This case demonstrates safe administration of onabotulinumtoxinA to an infant with a history of antitoxin-treated botulism, resulting in a transient improvement in control of infantile exotropia.
