Trial Comparing Part-time Versus Full-time Patching for Severe 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 full-time patching (all or all but one waking hour) for severe 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.

• Visual acuity in the amblyopic eye must be between 20/100 and 20/400.
• Visual acuity in the sound eye of 20/40 or better.
