Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To compare the effects of perceptual learning with patching on improving visual acuity and contrast sensitivity in payient with anisometropic amblyopia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with anisometropic amblyopia were randomized to patching or perceptual learning group. Corrected amblyopic logMAR visual acuity and contrast sensitivity function were measured at four-weekly intervals until visual acuity stabilized or amblyopia resolved. Improvement in visual acuity, contrast sensitivity, and the resolution of amblyopia were compared between groups.
