Prism Adaptation in Strabismus

Prisms have both diagnostic and therapeutic uses in strabismus. Many clinicians have popularized the use of prisms preoperatively to determine the target angle for surgery in esotropic patients. A review of the literature shows that preoperative prism adaptation, and the prism adaptation test is effective in predicting postoperative sensory and motor fusion in patients with acquired esotropia. Other patients may also benefit from prism adaptation.
