Objective To investigate the changes in the characteristics of anisometropia and stereopsis recovery in patients with refractive accommodative esotropia after receiving a refractive correction. Methods In this retrospective study, all patients with refractive accommodative esotropia with complete medical records were divided into groups based on the initial power of anisometropia [low (anisometropia≤1.0 D), moderate (1.0 D<anisometropia<2.5 D) or high (anisometropia≥2.5 D)] and initial visual acuity (binocular vision balance or the amblyopic eye). An independent samples t test, mixed linear model analysis and chi-square test was used for statistical analysis. Results After 6.8±2.8 years follow-up, 87(82.1%) patients had a lower degree of anisometropia, 14(13.2%) patients had a moderate degree of anisometropia, and 5(4.7%) patients had a high degree of anisometropia. ①The effect of the refractive correction on the initial binocular visual acuity showed a statistically significant improvement (t=9.787, P<0.05); ②The influence of the initial degree of anisometropia on stereopsis recovery was statistically significant (χ2=18.785, P<0.01); ③After wearing glasses, a decrease in the trend of the spherical equivalent was observed in the three anisometropia groups(F=142.913, P<0.01). Conclusion In this study, a higher initial degree of anisometropia is correlated with a lower initial visual acuity and a poorer subsequent stereopsis. With an increase in the amount of time glasses are worn, the initial states of anisometropia tend to change toward a more balanced refraction.
