Background/Aim. Infantile esotropia (ET), entitled as con-genital ET, is defined as an alternating, cross-fixational ET that occurs within the first 6 months of life. The aim of this study was to determine the long-term motor and sensory out-comes after surgical correction of patients with infantile ET. Methods. Medical records of 108 consecutive children who had bimedial rectus recession (BMR) initially for ET were re-viewed retrospectively. The patients were divided into 3 groups: the group I, surgery before one-year old; the group II, surgery between one and two-year old; the group III, surgery after two-year old. Results. No significant differences were determined among the groups for preoperative mean angle of deviation and refractive error (p > 0.05, for both). Develop-ment rate of dissociated vertical deviation (DVD) was greater (40%) in the group I, and the relationship between the rate of DVD and the timing of the initial surgery was statistically sig-nificant (p = 0.03). Risk for additional surgery was signifi-cantly greater in patients with a younger mean age at initial surgery (p = 0.01). Although measurable stereopsis rate was higher in the group I (35%, 32.4%, 27.8%, respectively) the difference among the groups was insignificant (p = 0.80). Conclusion. Patients with ET have limited potential of high grade stereoacuity despite the early alignment of eyes. Early sur-gery also has potential effects for the development of both infe-rior oblique overaction and DVD earlier.
