Official title: Binocular Amblyopia Treatment

Run by Retina Foundation of the Southwest · NCT03288948 · Data updated 2026-11-12

This study is testing if playing special games for 8 weeks can help children aged 4-10 with amblyopia see better compared to the usual 4-week treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 4-10 with strabismic, anisometropic, or combined mechanism amblyopia and specific visual acuity criteria.

Probably not a fit

Patients with coexisting ocular or systemic diseases, developmental delays, or those who have received binocular amblyopia treatment in the past 3 months may not benefit from this study.

What this trial studies

This study evaluates the effectiveness of new protocols for binocular amblyopia treatment, aiming to achieve better visual acuity recovery in children aged 4-10. It compares two alternative treatment protocols that extend the game treatment period beyond the traditional 4 weeks to an 8-week duration. The study involves an 8-week randomized controlled trial with three arms, assessing the outcomes of these new protocols against the standard 10% contrast-increment game protocol. Children who achieve certain visual acuity benchmarks will receive additional training to promote binocular vision.

Why it matters

Potential benefit: If successful, this treatment could significantly improve visual acuity and binocular vision in children with amblyopia.

How similar studies have gone: Previous studies have shown promise with contrast-rebalanced binocular treatments, but this specific approach is novel and untested.
