Use of Prisms: Are They Really Helpful? (Abstract)
Pamela J. Kutschke, C. O.
Prism adaptation is a relatively simple process of using Fresnel prisms to offset the angle of strabismus. Studies have shown prism adaptation to have a significant beneficial overall effect in patients with acquired, non-accommodative and partially accommodative esotropia. Patients with esotropia with a distance-near disparity have also been shown to have a beneficial effect following prism adaptation. Other patients, such as those with congenital esotropia, amblyopia or nystagmus, or previous surgery could benefit from prism adaptation. By broadening the scope of prism adaptation, surgical correction can be further enhanced and re-operation rates decreased.
