Binocular Treatment of Amblyopia Before and After Strabismus Surgery

The binocular treatment involves the completion of visual tasks via virtual reality goggles. The stimulus is presented to each eye separately, allowing for varying levels of contrast to be presented to each eye. (The visual task is therefore made more or less difficult with the variation of contrast presented to either eye.) Subjects will complete the computer-based visual tasks for approximately 36 hours total over the course of six weeks, or six hours per week for six weeks.

The sham treatment involves the same computer-based visual tasks and timeframe as the binocular treatment training but there will be no variation in contrast presentation to either eye.
