Occlusion therapy for exodeviations occurring in infants and young children.

The authors treated 38 patients with exodeviations by occlusion of the preferred eye for three to six hours daily for an average of 15 months. This treatment resulted in a significant improvement in the latency of the deviation as well as a decrease in the size of the strabismic angle. The majority of those patients responding to this method of therapy initially had good central and maintained fixation in each eye, an exodeviation of 20 prism diopters or less at both 6 and 1/3 m, and the presence of fusional vergence amplitudes.
