The purpose of this study was to examine a cross-disciplinary or holistic approach to vision and vision therapy. More specifically, it explored the potential usefulness of combining a short-term developmental model of psychotherapy with vision therapy to create a more favorable outcome in vision therapy. Three pairs of adult vision therapy patients were matched on the basis of expected
length of vision therapy treatment. The diagnostic categories included patients who were treated for strabismus, amblyopia, binocularity and accommodation
difficulties. Within each pair, patients were randomly assigned to vision therapy with or without psychotherapy. Dependent measures included gains in accommodation and convergence skills, subjective rating of decrease in visual
discomfort, time spent on vision therapy homework, rate of attendance and attrition of vision therapy sessions. In addition, psychological measures which focus on personality adjustment were given to all participants. The results
indicated that gains in vision therapy are greatly impacted by the patient's cognitions, emotions and self-perceptions. Psychotherapy appears promising as a supportive adjunct to vision therapy.
