Video game therapy could replace eye patches for lazy eye
NCT ID NCT07323953
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new digital therapy called AmblyoFix for treating lazy eye (amblyopia) in children aged 7 to 12. The therapy uses special software and red-blue glasses to play visual games that stimulate the weaker eye. Researchers will compare results to a group of children who previously received standard eye patching, to see if AmblyoFix is as effective and easier for kids to use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AmblyoFix binocular digital therapy (software and red-blue glasses)
- What this could lead to
- If successful, AmblyoFix could offer a more engaging and easier-to-stick-with alternative to eye patching for treating lazy eye in children.
- What could go wrong
- This is a small, early-stage trial with only 33 participants, and it compares against past patients rather than a simultaneous control group. The therapy may not work as well as patching for all children.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 7-12 years. * Unilateral amblyopia secondary to anisometropia and/or mild strabismus. * BCVA in amblyopic eye between 20/40-20/400 (0.3-1.3 logMAR); fellow eye ≥20/32 (≤0.2 logMAR). * Interocular difference ≥2 lines (≥0.2 logMAR). * Stable refractive correction for ≥16 weeks or \<0.1 logMAR change across two visits ≥8 weeks apart. * Cycloplegic refraction within 7 months meeting anisometropia criteria (e.g., hyperopia ≥+2.50 D). * Access to a suitable home environment (laptop and internet). * Parent/guardian consent and child assent (7+ year olds). Exclusion Criteria: * Atropine use within 2 weeks before starting treatment * Prior amblyopia treatment beyond refractive adaptation. * Myopia \>-6.00 D SE, previous ocular surgery, or other ocular pathology. * Severe cognitive/developmental delay impeding compliance. * History of light-induced seizures. * Inability/unwillingness to comply with digital monitoring. * Any condition compromising safety or trial integrity.
