The original research design involved a recall of 100 successfully treated strabismus patients released from vision therapy one to five years ago. An objective examination was to be performed to determine binocular status, and an analytical exam to determine refractive status, phoric posture, fusional ranges and accommodative ranges. A questionnaire was to be completed by each subject to evaluate subjective changes in the areas of binocularity, diplopia, suppression, and cosmetic alignment. The results were to be evaluated by the Flam Criteria as modified by Ludlam. The percent of the patient population which had retained binocularity by these standards was to be determined. After considerable project modifications, the research data was limited to subjective findings. Seven out of the seven patients surveyed reported (1) satisfaction with the way their eyes were working, (2) they were us1ng both eyes, and (3) considered their eyes properly aligned. Only one patient of seven reported either eye ever turning off. Five out of the seven responding reported that neither eye wandered at any time. These results are comparable to the results of the only previous longitudinal optometric study that has been conducted. According to our data, vision therapy for strabismus does have long-lasting results. Such results should provide impetus to the vision care specialist to provide treatment 1n the form of v1s1on therapy to their strabismus patients.
