Pediatric Eye Disease Investigator Group (PEDIG) Amblyopia Treatment Study

Wills Eye Study Doctor: Kammi Gunton, MD


Amblyopia (sometimes called “lazy eye”) is one of the most common causes of permanent decreased vision in children. The purpose of this study is to find out if treating amblyopia with glasses and patching at the same time improves vision as well as treating amblyopia first with glasses and then with patching, if needed.

The study is being conducted by the Pediatric Eye Disease Investigator Group (PEDIG) and is supported through funding from the National Eye Institute of the U.S. National Institutes of Health.


The study will include about 272 children across North America between the ages of 3 to <13 years old with no previous treatment for amblyopia, including glasses or contact lenses. Children eligible for the study will receive prescription eyeglasses and will be assigned to either start the study wearing glasses first (and wear an eye patch for 2 hours each day at a later date if needed) or wearing glasses and patching 2 hours each day at the same time to start. All children will have study visits every 8 weeks for 56 weeks.
