Comparison of Binocular Spectacle Prescription Versus Patching Therapy in Refractive Amblyopia Patients

Comparison of Binocular Spectacle Prescription Versus Patching Therapy in Refractive Amblyopia Patients

This study will examine on Refractive Amblyopia patients, whose amblyopia started due to longstanding uncorrected refractive errors.

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.
