| pubmed-article:7536239 | pubmed:abstractText | 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. Of 94 children undergoing such surgery between 1981 and 1991, 31 were developmentally delayed. Follow up ranged from 7 months to 202 months (mean 24 months). Surgical effect, defined as the change in alignment following each amount of surgery, was greater in the developmentally delayed group than in control subjects (P = .002). The increase in effect of the same amount of surgery in a developmentally delayed patient averaged 5.28 prism diopters, but was much larger in specific instances. Variability of effect was more marked among developmentally delayed children. We conclude that bilateral medial rectus recessions in developmentally delayed children may be better postponed in some cases, deferred for smaller angles, or decreased in amount. | lld:pubmed |
