The Use of Botulinum Toxin to Treat Infantile Esotropia

Injection of botulinum toxin type A into both rectus muscles is an alternative to surgery and has given good results in children with infantile esotropia. Reducing the angle of deviation can help restore binocular vision, which in turn will promote motor fusion and allow better control of the strabismus and may even lead to eventual healing. We report the result after 6 months of injection of botulinum toxin in the medial rectus in 6 children with infantile esotropia.
