Acute Acquired Comitant Esotropia and Digital Device Overuse in Children: a Three-Case Report
Downloads
Acute acquired comitant esotropia (AACE) is an uncommon strabismus involving sudden-onset inward eye deviation and diplopia. Recent trends suggest a rising incidence among youth, potentially linked to excessive digital device use.
This study reviews three children (ages 8–12) who developed AACE and diplopia following prolonged daily screen time (≥4 hours). Clinical evaluations revealed full ocular motility and no neurological deficits, with deviations ranging from 24 to 50 prism diopters.
Management transitioned from conservative monitoring to surgery once deviations stabilized. Interventions included bilateral medial rectus recession or unilateral recession-resection.
Postoperatively, all patients achieved orthotropia, resolved diplopia, and restored normal stereopsis. While a temporal association exists between heavy digital use and AACE, causality remains unproven. However, surgical intervention remains highly effective for restoring binocular function. Further research is necessary to clarify the mechanisms behind this "digital-age" presentation of strabismus.
