Long-term treatment results of accommodative esotropia

Abstract

To report the long-term ocular alignment outcomes of patients with accommodative esotropia. The medical records of consecutive patients ≤12 year of age diagnosed with refractive accommodative esotropia (esotropia eliminated or decreased to within 10(Δ) with full hyperopic correction) and followed for at least 10 years were retrospectively reviewed. A total of 107 patients were included (mean age, 4.81 ± 2.64 years). The mean follow-up period was 12.02 ± 2.25 years (range, 10-21 years). At the first examination performed 10 years after spectacle correction (mean, 10.2 years), 85 patients (79%) had orthophoria or esotropia ≤10(Δ) at both near and distance fixation, 14 (13%) had consecutive exotropia, 5 (5%) had decompensation and 3 (3%) had esotropia with a high ratio of accommodative convergence to accommodation (AC/A). The mean time interval between presentation and prescription of full hyperopic correction, initial cycloplegic refraction, and presence of amblyopia was not associated with consecutive exotropia, decompensation, or a high AC/A ratio esotropia. Whereas most patients with refractive accommodative esotropia maintained normal long-term ocular motility with spectacle treatment, some developed consecutive exotropia, nonaccommodative esotropia, or esotropia with a high AC/A ratio.
