We present the retrospective study to identify the clinical characteristics and the results of surgical correction for 50 patients with diagnosis of infantile esotropia at Soonchunhyang Chunan University Hospital from January 1990 to August 1994. The following results were obtained. Of 50 patients, 29(58%) patients were male and 21(42%)patients were female. Initial visit was most common between age of 2 and 3 years. 14% of patients were seen at age of 2 years or less. Average initial visit was 5.16 years. Esotropia was noted most commonly 2 to 4 month after birth in 23 patients(46%). Preoperative deviation angle was over 30PD in 88% of patients, and preoperative cycloplegic refraction showed +2.0D-O in 62%. The prevalence of associated findings such as amblyopia, dissociated vertical deviation(DVD), inferior oblique muscle overaction, and nystagmus were 32%, 14%, 38%, 4% by sequence. Surgical correction was performed before age of 2 year if noted at initial visit. The average age of surgical correction was 5.42 years. Bilateral medial rectus muscle recessions were performed in 30%, Unilateral resection and recession were performed in 35 patients(70%), Orthophoria(within +10 prism diopters) was achieved in 58% of the patients postoperatively. In 16% of patients residual esotropia of more than 20PD remained, which required further operation. These patients had average preoparative esotropia of 51PD and amblopia and inferior oblique overaction were seen in 87.5% preoperatively. We found that the two variables of amblyopia and inferior oblique muscle overaction lead to less satisfactory outcomes(P<0.01). Since amblyopia and inferior oblique muscle overaciton were seen more commonly in those patients that required reoperation. The average follow up time was 9.4 months.
