A retrospective review of the records of 96 patients with accommodative insufficiency has been completed. In addition to the major sign of reduced accommodative amplitude for their ages, I often found a reduction in the facility of accommodation, a smaller lag of accommodation, a tendency toward convergence insufficiency, slightly reduced fusional vergence and stereopsis, and a reduced nearpoint of convergence. Suppression was not generally found. The results of orthoptic exercises and/or a plus lens addition at near were examined. Most patients (90%) obtained some relief with treatment. About 53% had their objective and subjective problems totally solved during an average treatment period of 3.7 weeks. I determined the characteristics of the patients before and after treatment. The current state of the treatment of accommodative insufficiency is discussed.
