Purpose: To find clinical factors related to the long-term outcome of binocularity in accommodative esotropia.
Methods: Forty-nine patients with accommodative esotropia who were followed over 5 years after successful optical alignment within 8 prism diopters of orthophoria at near and distance with glasses including bifocals were included. The patients who had stereo acuity better than 50 seconds/arc and central fusion without suppression scotoma at the final visit were divided into the bifoveal fusion group and the others were divided into the peripheral fusion group. Clinical factors were analyzed between the two groups (Chi-square test, student t-test).
Results: Of the 49 patients, 15 patients were included in the bifoveal fusion group and 34 patients were included in peripheral fusion group. Mean follow-up was 88.9 ± 25.4 months. Clinical factors that were significantly related to the bifoveal fusion group were older age of onset, shorter duration of misalignment, intermittent esotropia at the initial visit and after initial optical correction, smaller residual deviations at distance after initial optical correction and at the final visit, and lesser amblyopia.
Conclusions: To obtain better levels of long-term binocularity, optical correction should be done as early as possible, before the presence of constant eye misalignment or amblyopia, and the residual esodeviations after optical correction should be kept as small as possible.
