摘要
Accommodative esotropia is a condition commonly encountered by pediatric ophthalmologists. Patient with accommodative esotropia wear hyperopic glasses to decrease accommodation which occasionally provide them with good vision without glasses. Children are known to have limited compliance with glasses and patching. Their limited cooperation can also lead to variability in angle measurement across visits and defer surgery. To cope with these challenges, our team offered botulinum toxin injection to the medial rectus as an optional treatment while waiting for compliance and deferring the surgery. This is retrospective study including data from 114 accommodative esotropia patients who were injected with botulinum toxin into the medial rectus between 2010 and 2017. Of these, 102 patients met the inclusion criteria. Almost half of the patients were boys (47.06%). The average angle deviation before injection was 40 prism diopters (PD). The post-injection angle averaged at 11 PD at 2 weeks, 19 PD at 3 months, and 25 PD at 6 months. At 6 months, 51 patients (50.00%) had satisfactory results, 17 (16.67%) had excellent results (ortho to esotropia < 10 PD) and 34 (33.33%) had small angle esotropia (esotropia 11-20 PD). All complications including ptosis (37.25%), exotropia (11.76%), and hypertropia (4.9%) were reversible. Botulinum toxin injection into the medial rectus for pediatric esotropia showed satisfactory outcomes in 50% of patients with minimal complications. The study showed no significant association of good outcomes with age at onset, age during injection, status of development, status of amblyopia, refractive error, and angle of deviation as analyzed by the statistical package for social sciences.
