[Botulinum toxin A in the treatment of concomitant strabismus in children]
1Centrum Okulistyki Dzieciecej w Warszawie.
Purpose:
To evaluate the results of treatment of esotropia, exotropia and hypertropia with botulinum toxin A.
Material And Methods:
72 children with esotropia, exotropia and hypertropia treated with intramuscular injection of botulinum toxin A.
Results:
Squint angle decreased 76% in children with alternant esotropia, 70% in children with monocular esotropia, 64% in alternant exotropia and 54% in monocular exotropia after treatment with botulinum toxin A. In hypertropia squint angle reduced in 50%.
Conclusions:
The use of injections of botulinum toxin A in treatment of concomitant strabismus improves position of eyes, which creates better conditions for development of localization with normal retinal correspondence.
