INTRODUCTION: Btx A uses strabismus for congenital esotropia or large angle horizontal strabismus in adults and acute paretic strabismus when surgical treatment of the ocular muscles is not yet possible. In this study demonstrated that long-term efficacy of Botulinum toxin A in patients with Infantile Esotropia.
METHODS: A single-center, retrospective designed study, age of patients ≤ 24 months with esotropia onset before 12 months. Successful outcome was defined as ocular alignment within 8-10 Prism Diopter of orthotropia.
RESULTS: The record review identified of 6 patients; 2 boy and 4 girls. Mean age was range from 8 to 24 months. Mean follow-up time was 30.5 ± 12.4 months. Effective results was achieved and deviation was changed from 34.2 ± 5.8 PD (range: 25-40 PD) to orthophoria at near after the botulinum toxin injections.
DISCUSSION AND CONCLUSION: Botulinum toxin injection may be considered a primary treatment patients with infantile esotropia and achieved long-term results. Further longitidunal studies are require to support to this situation.
