Abstract

Purpose: We performed a prospective cohort study to evaluate the effectiveness of disc synoptoscope on binocularity in patients with abnormal binocular vision.

Methods: 39 eligible subjects were recruited for visual therapy with disc synoptoscope in treatment group and 38 were just observed as control.

Results: Simultaneous perception in treatment group was better than controls at 6-month visit (p < 0.05). Fusional amplitude improved in treatment group but decreased in control group at 3- and 6-months visits (p < 0.001). Near and distance stereopsis in treatment group were better than controls at 3- and 6-months (p < 0.05). The improvements of monocular and binocular acuity in treatment group were better than controls at 3- and 6-months (p < 0.05). Postoperative recurrence rate in treatment group was lower than controls (p < 0.05).

Conclusion: Visual therapy with disc synoptoscope is effective in improving short-term binocular vision for the patients with abnormal binocular vision; disc synoptoscope could serve as an effective home-based visual therapy instrument.

Keywords: Binocular vision; Disc synoptoscope; Treatment effect; Visual acuity; Visual therapy.
