BACKGROUND: Although vision therapy has reportedly been very successful in elimination of asthenopic symptoms (excessive tearing, itching, burning, visual fatigue, and headache) in adults with convergence insufficiency, controlled studies have not been performed, and a clinical bias exists against prescribing vision therapy for adults with convergence insufficiency. METHODS: Sixty adult males over the age of 40 years (median age, 65 years) with convergence insufficiency were divided into three treatment groups: office-based vision therapy with supplementary home therapy, home therapy only, and a control group. RESULTS: Vision therapy was successful in 61.9% of patients who received in-office plus home therapy, in 30% of patients who received home therapy only, and in 10.5% of the control group. The success rate for patients who received active in-office vision therapy supplemented with home procedures was significantly greater than that for controls. Home therapy alone was less successful than in-office therapy. The success rate obtained with home therapy alone was not significantly greater than that demonstrated by controls. CONCLUSIONS: Vision therapy is effective in eliminating asthenopia (eyestrain) and improving convergence function in adult patients. In-office therapy combined with home therapy tends to produce better results than does home therapy alone. (Birnbaum MH, Soden R, Cohen AH.
