Patients with initial esotropia and orthophoria had a higher amount of drift, at 86.7% and 70%, respectively, than patients with exotropia at 26.1%, according to a study examining exotropic drift and ocular alignment after surgery for intermittent exotropia.
However, while nearly all patients had exotropic drift in the study, 29 patients (60.4%) achieved motor success.
"The success rate appears to be unaffected by initial ocular alignment, suggesting that deliberate initial overcorrection may be unnecessary," the study authors said.
The retrospective study looked at 48 patients aged 1 to 10 years old who had bilateral lateral rectus recession for intermittent exotropia. Ocular deviations were analyzed preoperatively and at 1 week, 1 month and 6 months postoperatively. For motor success to be achieved, ocular deviation had to be within 10 prism D of orthophoria at 6 months postoperatively.
Follow-up ranged from 6 months to 3 years.
No statistical difference was found at 1 week postoperatively between ocular alignment and final motor success, the authors said.
