Abstract
Occlusion as a treatment for amblyopia has been thought to carry a risk of increasing the size of an esotropia. We studied ninety three patients with ET treated with occlusion therapy. Our study shows that occlusion therapy does not carry a significant risk of increasing a cosmetically acceptable ET to cosmetically unacceptable. In fact there seems to be an equal chance following occlusion therapy for the size of the esotropia to decrease.
