Intermittent exotropia: a novel surgical algorithm based on a postocclusion distance-near relationship

Abstract

For the preoperative evaluation of patients with intermittent exotropia, prior studies have revealed that prism alternate cover testing at distance and at near should be performed after a period of monocular occlusion, and that the use of a reading add at near helps to exclude accommodative convergence. Using these evaluation techniques, a performance improvement project was undertaken to evaluate a dosage-modification algorithm created to improve outcomes with bilateral lateral rectus recession surgery.
