About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

interocular visual acuity difference ≥0.3 logMAR

Disqualifiers

prematurity ≥8 wk

coexisting ocular or systemic disease

developmental delay

strabismus >5 pd
