Changes in ocular alignment under general anesthesia in children with intermittent exotropia correlated strongly with preoperative strabismus angles and helped predict surgical outcomes, according to a study reported on OSN SuperSite.
The study examined 40 children with extropia and a mean age of 6.7 years, as well as a control group with a mean age of 6.3 years and no extropia. Investigators looked at digital photographs taken before and after general anesthesia was administered with the children in the primary supine position. At one day and one year after surgery, preoperative angle of deviation was compared with changes in the anatomic interpupillary distance after general anesthesia.
The study showed that children in both groups had increased anatomic interpupillary distance after general anesthesia. Average changes in eye position were 3.78 percent in the study group and 3.15 percent in the control group.
Five of seven children whose ocular alignment changes were outside the 80 percent confidence interval for expected outcomes had poor results one day after surgery, and four of the seven children had poor results after a year.
