Trial Comparing Part-time Versus Minimal-time Patching for Moderate Amblyopia

Completed · Phase 3

Conditions studied: Amblyopia

In brief

The goals of this study are: * To determine whether the visual acuity improvement obtained with part-time (6 hours) patching is equivalent to the visual acuity improvement obtained with minimal patching (2 hours) for moderate amblyopia. * To develop more precise estimates than currently available for the visual acuity improvement that occurs during treatment of amblyopia with patching. * To identify factors that may be associated with successful treatment of amblyopia with patching.
