Does Video Game Play Induce Plasticity in the Visual System of Adults With Amblyopia?

University of California, Berkeley·interventional·Posted Oct 19, 2010·Updated May 17, 2016

In Brief

A clinical study evaluating Perceptual learning, Video Game, and 1 other intervention for Amblyopia. Completed, enrolled 20 participants across 1 site.

Detailed 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.

Interventions

Perceptual learningbehavioral

Research participants will be asked to practice a visual discrimination task (e.g. position acuity, contrast sensitivity, stereoacuity etc) in our laboratory for a period of time (2 hrs/day, 5 days/week).

Video Gamebehavioral

Research participants will be asked to play "off-the-shelf" video games in our laboratory for a period of time (2 hrs/day, 5 days/week).

Crossover (Occlusion therapy + Video Game)behavioral

Phase 1. Research participants will be required to cover the good eye during the day in order to push the brain to use the amblyopic eye (2 hrs/day, 5 days/week for 2-4 weeks). Phase 2. Research participants will be required to cover the good eye during the day in order to push the brain to use the amblyopic eye (2 hrs/day, 5 days/week for 2-4 weeks).
