Trial Comparing Patching Versus Atropine for Amblyopia in 7 to < 13 Year Olds
Completed · Phase 3
Conditions studied: Amblyopia
In brief
The purpose of this study is: * To compare the effectiveness of weekend atropine plus near activities and daily patching plus near activities for moderate amblyopia (20/40 to 20/100) and severe amblyopia (20/125 to 20/400) in improving vision in the amblyopic eye of 7 to \<13 year olds. * To determine the maximum improvement in vision of the amblyopic eye with each treatment. * To determine whether amblyopia is associated with structural abnormalities of optic nerve fiber layer.
