Improving Spatial and Temporal Vision in Adult and Juvenile Amblyopia

University of California, Berkeley·interventional·Posted May 4, 2010·Updated Nov 14, 2022

In Brief

A clinical study evaluating Perceptual learning, Video Games, and 1 other intervention for Amblyopia. Completed, enrolled 50 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 both adults and children 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 Gamesbehavioral

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).

Occlusion therapybehavioral

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).
