Overview

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.

Interventions

Exp GroupDIAGNOSTIC_TEST

Binocular Spectacle prescription are therapeutic tools used to correct refractive errors in visually impaired patients. They improve Visual acuity as well as other visual functions in Amblyopic and visual impairment patients. They stimulate weaker eye to generate visual impulse and stimulate visual cortex to improve stereopsis and fusion.

Control GroupDIAGNOSTIC_TEST

Patching therapy is a gold standard tool used world wide to correct visual acuity in amblyopic patients. This tool is used by occluding stronger eye with a patch or bandage or fogging lens and stimulating amblyopic eye to generate visual stimulus to motivate visual cortex.

Outcomes

Primary Outcomes

Binocular single vision

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."

Time frame: 12 Months

Visual Acuity

it will be assessed monocularly by logMAR visual acuity chart at 4 meter distance.

Time frame: 12 months
