Abstract

Aim: To assess the role of Botox injection and surgery in treatment of Congenital Esotropia.

Methods: Retrospective study of Congenital Esotropes who had Botox injection alone or with surgery was carried out. Evaluation included visual acuity, degree of deviation, cycloplegic refraction, amblyopia, fixation, extra ocular movements and fundus examination. Botox injection and surgical correction for macrotropia in congenital strabismus were treatment methods used.

Results: 837 patients having Congenital Esotropia were part of this retrospective study. All presented or developed esotropia before 6 months of age. Esotropia ranged from 11 to 50 Prism Diopters. These had average follow up of 8.5 years. 289(34.52%) patients were treated with Botox injection only. 347(41.45%) were treated with Botox injection and bilateral medial rectus recession. 201(24.01%) had bilateral medial rectus recession and one lateral rectus resection. 701(83.75%) had Orthotropia and 136(16.24%) had microtropia at the end of follow up.

Conclusion: Botox injection, bilateral medial rectus recession with/without unilateral lateral rectus resection are treatment options of choice for congenital esotropia.

Keywords: Esotropia, Botox injection and Bilateral medial rectus recession.
