Recurrent esotropia following early successful surgical correction of congenital esotropia.

A study was conducted using a group of congenital esotropes who had an adequate surgical alignment prior to 18 months of age, to determine how many of them would redevelop esotropia. In the group that redeveloped the condition, a high percentage of the esotropia was accommodative in nature and was therefore able to be corrected with spectacles. Both the initial refractive error and changes in refractive error were noted to be significant. This study emphasizes the importance of monitoring the refractive state continuously, especially in children with subnormal fusion.
