Efficacy of Botulinum Toxin Type A for Acute Acquired Comitant Esotropia: An Age-Stratified Two-Year Follow-Up Study

NCT06966999

The goal of this clinical trial is to assess and compare the efficacy of two-year follow-up botulinum toxin type A （BTXA) in the treatment of acute acquired comitant esotropia (AACE) across five age groups: ≤6 years, \>6 to ≤12 years, \>12 to ≤20 years, \>20 to ≤30 years, and \>30 years. For patients \>12 years presenting with large-angle esotropia (\>50 PD), primary surgical intervention was recommended as the preferred approach to minimize failure and recurrence risk. Conversely, for patients ≤12 years, BTXA injection was maintained as the first-line treatment regardless of the deviation angle.
