Study Summary
Amblyopia, a developmental abnormality that impairs spatial vision, is a major cause of vision loss, resulting in reduced visual acuity and reduced sensitivity to contrast. This study uses psychophysical measures to study neural plasticity in adults with amblyopia.
Primary Outcome
Improvement in amblyopic vision : visual acuity and stereoacuity
Interventions
- BEHAVIORAL Perceptual learning
- BEHAVIORAL Video Game
- BEHAVIORAL Crossover (Occlusion therapy + Video Game)
