Amblyopia in Infantile Esotropia

ABSTRACT

Sixty-eight children who had undergone surgery for infantile esotropia were analysed. The mean follow-up time was 2.7 years. Thirty-two patients without amblyopia prior to surgery remained as such postoperatively except one child(3.1%). There were twenty-seven children that received treatment for amblyopia prior to strabismus surgery. Out of these, twenty children(20/27, 74%) developed recurrent amblyopia in postoperative follow-up period. Dissociated vertical deviation and/or inferior oblique overaction occurred in 21 children(21/39, 54%) in the group free of amblyopia, while those occurred in 16 children(16/29, 55%) in amblyopic group, postoperatively. In conclusion, children without amblyopia before surgery remained as such postoperatively. The development of postoperative vertical deviation such as DVD and IOOA is not related to the existence of amblyopia in postoperative periods.
