Alignment success following medical rectus recessions in normal and delayed children.

Others have suggested that developmentally delayed children, who are frequently esotropic, have a poor prognosis following esotropia surgery. To date, no comparison of success rates in normal and delayed children following similar surgery has been made. We compared our long-term results following graded bilateral medial rectus recessions in consecutive normal (n = 62) and delayed (n = 29) children.

Exaggerated effect of bilateral medial rectus recession in developmentally delayed children.

Many have suggested that the esotropia associated with developmental delay should be considered separately. However, the esotropia surgery recommended for developmentally delayed children has been similar to that performed in normal children. We have noticed a tendency for developmentally delayed children to develop consecutive exotropia following bilateral medial rectus recessions.
