INTRODUCTION: This study was an assessment of factors related to the development and maintenance of binocular sensory function after successful alignment of accommodative esotropia (AE).
METHODS: A total of 107 patients aged <12 years with ≥6 months follow-up were included in the study. The variables of age at onset of deviation, duration of deviation before treatment, the amount of uncorrected distance and near deviation, hyperopia, anisometropia, and accommodative convergence to accommodation ratio (AC/A) were evaluated.
RESULTS: The study patients had a mean age of 4.9±2.5 years and a mean length of follow-up of 34.3±28 months. Anisometropia was identified in 26.1% of the participants. Anisometropic patients had a greater degree of hyperopia (mean: 5.02±2.07 D) than the patients without (p>0.05). Amblyopia was seen in 25% of the patients with anisometropia, and in 19% of those without (p<0.05). The binocular visual function of the 2 groups was not significantly different (p>0.05). The age at onset of deviation and the duration of deviation did not affect the final outcome (p>0.05 for all). The degree of initial uncorrected distance deviation had a significant effect on the development of amblyopia, fusion, and contoured stereopsis (p<0.05 for all), while the degree of near deviation without correction had a significant effect only on contoured stereopsis.
DISCUSSION AND CONCLUSION: The degree of uncorrected distance and near deviation had a negative impact on binocular vision and stereopsis in AE. The presence of anisometropia, age at onset of deviation, duration of deviation before treatment, high hyperopia, and high AC/A did not pose a significant risk for impaired binocular function.
