Congenital esotropia.

The prognosis for congenital esotropia remains guarded. Monofixation syndrome currently is the best widely reported result following surgery. The reoperation rate in congenital esotropia (including reoperations for horizontal misalignment, dissociated vertical deulation, and inferior oblique overaction) also is high, approaching 50%. The role of very early surgical intervention needs to be examined further and could result in dramatic improvement in the long-term outcomes associated with congenital esotropia.
