Subjects and Methods
This study was approved by the Institutional Review Board of Samsung Medical Center (Seoul, Republic of Korea). The medical records of patients with esotropia with an accommodative component after surgery for infantile esotropia (secondary group) and patients with primary accommodative esotropia (primary group) examined at Samsung Medical Center between January 1994 and December 2009 were reviewed retrospectively. Patients in the secondary group were considered for inclusion if they developed
Results
Of the 177 patients who underwent strabismus surgery for infantile esotropia during the study period, 79 had hyperopia of ≥ +1.5 D and corrected esotropia of ≤10Δ with full cycloplegic hyperopic correction. Of these 79 patients, 41 met inclusion criteria. In the primary group, 224 patients had hyperopia of ≥ +1.5 D or and corrected esotropia of ≤10Δ with full cycloplegic hyperopic correction. Of these, 101 met inclusion criteria.
The baseline characteristics of the two groups are described in
Discussion
The prevalence of accommodative esotropia among normal children with hyperopia of ≥ +4.0 D during infancy is 10%-20%.12, 13 In this study, 79 patients (45%) developed significant esotropia with an accommodative component, which decreased to <10Δ with hyperopic correction among the 177 patients who underwent strabismus surgery for infantile esotropia. They had a much lower mean initial refractive error than patients with primary accommodative esotropia. Previous studies have reported prevalence
