Surgical Results of Intermittent Exotropia in Pediatric versus Adult Group

ABSTRACT

We analyzed the change of the amount of postoperative deviation between pediatric group (younger than 18 years) and adult. group (older than 18 years) with intermittent exotropia. All of the 141 patients were treated by bilateral recession of lateral rectus muscle. Among 141 patients, 111 were overcorrected immediately after surgery. Among 111 overcorrected patients, 64 were children and 47 were adults. Fifty of 64 overcorrected pediatric patients were satisfied after 6 m.on`ths after surgery, but only 22 of 47 overcorrected adult patients were satisfied. Twenty two of 26 overcorrected 10-15delta immediately after surgery in pediatric group and 17 of 24 overcorrected under 10delta, in adult group were satisfied after 6 months after surgery. Between the two groups, the figure of change of postoperative deviation were different. In pediatric group, postoperative deviation was rnuch naore decreased at. 6 months after surgery, but, changes were less significant in adult group. We suggest that immediately after surgery, a small consecutive esotropia of 10 to ISA is desirable in children but. esotropia less than IDA in adults.
