Lazy eye shooter: making a game therapy for visual recovery in adult amblyopia usable

As many as three quarters of a million preschoolers are at risk for amblyopia in the United States, so appropriate screening and accessible treatment are very important.

Lazy Eye Shooter is a game treatment that takes advantage of these findings in that the software contains a dichoptic display in a First Person Shooter (FPS) action video game. FPS games are unfortunately among the most difficult games to learn for naïve subjects.

We describe several methods we have used to make the overall experiences of subjects more positive and discuss current preliminary results from the use of Lazy Eye Shooter
