Amblyopia
Conditions
Brief summary
The objective of the study is to demonstrate the safety and efficacy of Luminopia One in amblyopia patients with amblyopia associated with anisometropia and/or with mild strabismus.
Detailed description
The proposed study is a multi-center randomized controlled clinical trial which compares the mean change in amblyopic eye Best Corrected Visual Acuity from baseline with Luminopia One (therapeutic) to refractive correction (control). One-hundred and forty participants (n = 140) aged 4-7 years will be enrolled. Participants will be randomized 1:1 to the therapeutic group , to use Luminopia One, or the control group, to undergo continued refractive correction, for 12 weeks of treatment.
Interventions
Luminopia One is a virtual-reality based digital therapeutic that applies therapeutic modifications in real-time to cinematic content to rebalance visual input and treat amblyopia.
