ABSTRACT
Anisometropia, or the difference in the refractive error between the two eyes of an individual, is a well-known cause of amblyopia. It is widely believed that patching of the better seeing eye can improve vision in the affected eye (Helveston E & Ellis F 1980). Unsurprisingly, widely differing treatment regimens have been promoted; some practitioners favoring full time (von Noorden G.K. 1990; Nelson B.L. et al. 1991) while others just a few minutes occlusion each day (Watson et al. 1985). The purpose of this study is to examine the effectiveness of correction of the refractive errors alone or with minimal patching on the improvement of amblyopia.
