Botulinum toxin type A success rates and predictive factors for favourable outcomes in paediatric patients with acquired esotropia.

ABSTRACT:

Purpose

This study aimed to assess the efficacy of botulinum toxin type A in treating childhood-acquired comitant esotropia and identify predictive factors of treatment success.

Methods

This retrospective, consecutive, non-comparative cohort study included children under 18 years treated with botulinum toxin type A for acquired comitant esotropia between 2013 and 2019, with a minimum 6-month follow-up. The primary outcome was the success rate of achieving horizontal deviation within 10 prism dioptres at 6 months post-botulinum toxin type A treatment.

Results

In total, 49 children with a mean treatment age 8.10 ± 4.02 years were assessed. The three most common types of esotropia were acute acquired comitant, intermittent, and cyclic esotropia (57.2%, 20.4%, and 12.2%,
