Abstract:
Occlusion therapy has been reported to improve the motor phase and sensory phase of exodeviations. We performed occlusion on the preferred eye in intermittent exotropia for three hours a day. Average follow-up time was 15.8 weeks. The frequency of tropic status of exodeviation was decreased in 21 cases(70%). In two cases intermitent pattern was changed to exophoria, and in one case, to exotopia. The size of the deviation angle was changed from 28.93 +/- 7.6 prism diopter(PD) to 24.03 +/- 7.9 PD(p<0.01). In 13 cases(43.3%) the size of the deviation angle decreased more than 6 PD, increased more than 6 PD in one case(3.3%), and in 16 cases(53.3%) the size of deviation angle showed no change. The preference pattern changed from monocular to alternating type in 5 cases. Stereopsis improved in 24% of the cases and did not deteriorate in Others.
