Comparison of Two Treatments for Strabismus Correction: Botulinum Toxin A Associated to Surgery and Surgery Alone

Summary

Two different treatments were given to large angle horizontal strabismus (eso and exotropia) adult patients who agree to participate of the study. Inform consents were required for participants. Group 1 (12 patients) received conventional recess-resect surgery plus intraoperative injection of botulinum toxin A (5U). Group 2 (11 patients) received only conventional recess-resect surgery. The patients were randomly located in one of the groups. The angles of horizontal deviation were compared between the groups before and six months after treatment.
