Full hyperopic correction shows improved outcome for exotropia over partial correction

ORLANDO, Fla. — Using full hyperopic correction in pediatric patients resulted in more cases having resolution and no worsening of exotropia than those with partial correction, a study found.
"Partial correction [is] more likely to result in no change or worsening of exotropia," Iris S. Kassem, MD, PhD, and colleagues said.
Results of their study were presented in a poster at the American Association for Pediatric Ophthalmology and Strabismus meeting here.
They conducted a retrospective chart review of 26 patients aged 2.5 months to 9 years with at least 10 D of exotropia and 4 D or more of hyperopia. The cases were divided into three treatment groups: full hyperopic correction, partial correction or no correction.
A total of 18 children had known exotropia before treatment, and of those, 15 children received and used spectacles, one child had part-time patching therapy and two children were lost to follow-up.
In addition, six patients had spectacle correction and exotropia on referral, and two had no known deviation before spectacle correction.
Five children underwent strabismus surgery. Surgery was most likely needed in cases with poor control before treatment, larger-angle exotropia and exotropia that continued after spectacle correction, the study authors said.
