Surgical Outcome of Intermittent Exotropia With Improvement in Control Grade Subsequent to Part-time Preoperative Occlusion Therapy

Intermittent exotropia is the most frequent type of strabismus encountered in childhood and accounts for more than 50% of cases of exotropia in children.1 In addition to surgery, management of intermittent exotropia includes orthoptic exercises, minus lenses or prisms, and part-time occlusion regimens.2 Freeman and Isenberg3 reported that all 11 patients in their study who underwent part-time patch occlusion of the non-deviating eye for 4 to 6 hours a day converted to heterophoria or orthophoria, at least temporarily.
