Vision therapy or orthoptics is the standard treatment for symptomatic accommodative-vergence anomalies and amblyopia. Computerization of vision therapy has improved treatment results by: standardizing protocols; providing positive or negative reinforcement based upon responses; eliminating experimental (therapist) bias in research and/or therapy; and standardizing stimuli and methodology for diagnosis/treatment. This paper reviews the literature regarding the efficacy of the automated treatment of accommodative vergence anomalies, and amblyopia. The use of the Computer Orthopter™, its home based program, HTS™ and amblyopia programs are discussed in detail.
RDSs presented in an operant conditioning paradigm have resulted in improved therapy for patients with accommodative and vergence dysfunctions. Numerous studies have demonstrated that computerization of VT techniques are superior to traditional methods of therapy. Computerization improves patient motivation, eliminates experimental bias, simplifies therapy goals, provides immediate reinforcement to encourage correct responding, and provides meaningful data to evaluate progress. The significant and increasing number of home computers and the policies of managed care have fostered the use of computer based VT to supplement office therapy or be a stand alone modality for home based therapy.
