简要总结
This study will examine on Refractive Amblyopia patients, whose amblyopia started due to longstanding uncorrected refractive errors.
详细描述
There will be a comparison of two treatment methods i.e. Patching and Binocular Spectacle Prescription used to cure amblyopia patients. In binocular spectacle correction, we will slightly blur the good eye and fully correct the amblyopic eye so that binocular functions stimulate and improve after the treatment. Literature suggests that Patching improve monocular functions but there is no significant improvement in binocular functions.

结局指标
主要结局
Binocular single vision
时间窗: 12 Months
it will be measured by Worth 4 Dot test in which patient will see four lights ( two green, one red and one white light) with red and green glasses and both eyes will see at once. stereopsis: it will be measured grossly by seeing the fly picture at the card and fine stereopsis will be measured by different pictures available on the card. it will be assessed by wearing polarising glasses during test and see the 3D pictures."
Visual Acuity
时间窗: 12 months
it will be assessed monocularly by logMAR visual acuity chart at 4 meter distance.
