Trial Summary

What is the purpose of this trial?

To evaluate the effectiveness of enhanced binocular amblyopia treatments in achieving a more complete and stable recovery.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, you must be willing to stop patching treatment for the 12-week study period.

What data supports the effectiveness of the treatment Binocular Amblyopia Treatment, Binocular Amblyopia Therapy, Dichoptic Training, Balanced Binocular Viewing Therapy, Luminopia, CureSight, Vivid Vision for lazy eye?

Research shows that binocular treatments, like games and movies that balance visual signals, can improve vision in children with amblyopia (lazy eye) by enhancing the use of both eyes together. Studies comparing these treatments to traditional patching methods suggest they may be effective in improving visual acuity and binocularity.12345

Is binocular game therapy for amblyopia safe for humans?

The research on binocular game therapy for amblyopia, including treatments like Luminopia, suggests it is generally safe for humans, with studies focusing on its effectiveness and adherence rather than safety concerns.12567

How is the Binocular Amblyopia Treatment different from other treatments for lazy eye?

Binocular Amblyopia Treatment is unique because it uses games or movies that require both eyes to work together, helping improve vision by rebalancing the images seen by each eye, unlike traditional methods like patching which cover the stronger eye to force the weaker one to work harder.34589

Eligibility Criteria

This trial is for children aged 4-10 with lazy eye, who have a certain level of vision in their amblyopic (weak) and fellow eyes. They must be able to play binocular games, have not received similar treatments recently, and agree to avoid patching during the study. Children with significant strabismus, premature birth history, other diseases or developmental delays cannot participate.

Inclusion Criteria

Findings from Research

The BRAVO study is a double-blind, randomized, placebo-controlled trial involving 108 participants aged 7 years and older, aimed at evaluating a novel home-based binocular treatment using a videogame for amblyopia.
The primary goal is to determine if this interactive treatment can significantly improve visual acuity in the amblyopic eye compared to a placebo, marking a potential new approach for treating amblyopia in older children and adults.
Binocular treatment of amblyopia using videogames (BRAVO): study protocol for a randomised controlled trial.Guo, CX., Babu, RJ., Black, JM., et al.[2019]
In a study involving 182 children aged 4 to 6 years with amblyopia, the use of a binocular iPad game, Dig Rush, resulted in a greater improvement in amblyopic-eye visual acuity after 4 weeks compared to continued spectacle correction alone, with an adjusted difference of 0.5 logMAR lines.
After 8 weeks, the improvement in visual acuity was not significantly different between the two groups, suggesting that while the binocular treatment shows promise, further modifications may be needed to enhance its long-term efficacy.
A Randomized Trial of Binocular Dig Rush Game Treatment for Amblyopia in Children Aged 4 to 6 Years.Manny, RE., Holmes, JM., Kraker, RT., et al.[2023]
A study involving 27 amblyopic children aged 4-10 showed that passive viewing of contrast-rebalanced dichoptic movies significantly improved visual acuity in the amblyopic eye over a 2-week period.
The improvement in visual acuity was comparable to that achieved through more traditional treatments like binocular games or occlusion therapy, indicating that this passive method could be an effective alternative for treating amblyopia.
