Binocular iPad treatment for amblyopia

Krista Kelly, PhD


BACKGROUND: Current amblyopia treatments (patching the fellow eye or blurring vision of the fellow eye with drops or filters) are based on the premise that amblyopia is a monocular disease that can be remedied by forcing the child to use the lazy eye. Yet, amblyopia develops only when there is binocular discordance (images in the two eyes do not match due to strabismus, anisometropia, or cataract).

GAP: Amblyopia is a disorder of binocular vision and can only be treated effectively if the primary binocular dysfunction is treated. My study will evaluate the effectiveness of a binocular treatment for amblyopia, and compare this treatment with the standard monocular treatment of patching.

HYPOTHESIS: Binocular iPad game treatment will improve visual acuity and binocular vision in children with amblyopia due to strabismus, anisometropia, and congenital unilateral cataract. Binocular iPad game treatment will be more effective than the traditional treatment of patching of the fellow eye in improving visual acuity and binocular vision in children with amblyopia.

METHODS: In this randomized crossover design, I will assess visual acuity and binocular vision outcomes in children with amblyopia after binocular iPad game and monocular patching treatments to determine which is more effective.

RESULTS: Pending.

IMPACT: Amblyopia (‘lazy eye’) is the most common pediatric eye disease that affects 1 in every 25 children in the US. If proven effective, the binocular iPad treatment has the potential to be a game-changer in the way amblyopia is treated, impacting the vision outcomes of amblyopic children nationwide within the next 3 to 5 years.
