ABSTRACT

Introduction: Perimuscular injection of Botulinum Toxin A is a therapy that may modify the eye alignment through a temporal muscle paralysis. Its utility has been documented in strabismus treatment, including non-accommodative esotropia patients. The aim of this study is to show the outcomes obtained in the treatment of non-accommodative esotropia.
Method: A chart review of those patients with non-accommodative esotropia younger than 24 months of age who were treated with perimuscular injection of Botulinum toxin A in both medial rectus were performed.
Results: We included 51 patients with non-accommodative esotropia with deviation greater than 20 DP (mean: 45 DP). We obtained the following results during a 12 month follow up period: eye alignment: 34.78%, residual esotropia ‹ 15 DP: 39.13%, residual esotropia › 15 DP: 17.39%, consecutive exotropia: 8.69%. One session of Botulinum toxin A injection was sufficient in 75.54% of the cases.
Conclusion. Botulinum toxin injection into bilateral medial rectus corrected 73.91% of non-accommodative esotropia cases. One application of Botulinum toxin corrected strabismus in most of the patients. Blepharoptosis was the most frequently seen complication. No changes in the refractive status were observed in any patient.
