Purpose: To evaluate the clinical features, surgical outcome and factors influencing the surgical outcome of infantile esotropia according to the age at surgery.
Methods: Seventy patients with infantile esotropia followed for at least 6 months after surgery, were enrolled in a retrospective study. Patients were divided into 2 groups. Group 1 included 25 patients who underwent surgery before the age of 24 months and group 2 included 45 patients who underwent surgery after 24 months of age. The clinical characteristics including age at the initial visit, refractive error, angle of deviation, associated strabismus, success rate and reoperation rate were analyzed according to the age at surgery.
Results: The mean angle of esodeviation before surgery was 41.71PD and refractive error was +1.26D. Patients underwent bimedial rectus recessions at the mean age of 67.33 months. The age at the initial visit was significantly older in group 2. Surgical success is defined as the ocular alignment within ±10PD in primary position at the last visit. Fourteen patients (56%) from group 1 and 29 (64.4%) from group 2 obtained surgical success. Reoperation was performed in 8 patients (32%) from group 1 and 8 (17.8%) from group 2, which was not statistically significantly different. Stereopsis better than 3,000 seconds of arc was obtained in 3 patients (50%) from group 1 and 16 (76.2%) from group 2.
Conclusions: In group 2, the late-surgery group, the success rate was 64.4% and stereopsis was obtained in 76.2%. Surgical results were not different between the two groups.
