Video Treatment for Amblyopia
Retina Foundation of the Southwest
Summary
The purpose of this study is to determine whether viewing asynchronous movies leads to better visual outcomes in young children with amblyopia than standard-of-care occlusion therapy with an adhesive patch and whether this is associated with better adherence to treatment.
Description
This is a single-site randomized clinical trial to compare treatment of amblyopia by viewing asynchronous movies to standard-of-care occlusion therapy with an adhesive patch. Participants will be referred from local pediatric ophthalmologists. Following informed consent, children will complete baseline testing to confirm eligibility and provide pre-treatment measurements of visual acuity, suppression, stereoacuity, motor skills, self-perception, and quality of life. Eligible children will then be randomly allocated to either patch-free occlusion therapy or standard-of-care occlusion therapy wi…
