Improving Normal and Amblyopic Vision with Video Games and Perceptual Learning
Status: Recruiting
Location: See location...
Intervention Type: Behavioral
Study Type: Interventional
Study Phase: Not Applicable
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 both adults and children with amblyopia.

Participants
Target number of participants: 180
Treatments
Experimental: Video Games
Participants will be required to play video games for a period of time: 1-2 hrs per session, 4-5 sessions/week for \~1-6 months
Experimental: Perceptual learning
Participants will be required to practice a visual discrimination task (e.g. visual acuity, position acuity, contrast sensitivity, \& stereoacuity) for a period of time: 1-2 hrs per session, 4-5 sessions/week for \~1-6 months
Active_comparator: Occlusion therapy
Participants will be required to cover the dominant eye during the day in order to push the brain to use the fellow amblyopic eye: 1-2 hrs per session, 4-5 sessions/week for \~1-6 months
