An Active Approach to Treat Amblyopia: Video Game Play

Amblyopia Clinical Trial

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

Status Completed

Clinical Trial 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.

Clinical Trial Description

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. Our previous findings (see CITATIONS) show that the adult amblyopic brain is still plastic and malleable, suggesting that active approach is potential useful in treating amblyopia. The goal of this project is to assess the limits and mechanisms of neural plasticity in amblyopic spatial vision. This study uses psychophysical measures to study neural plasticity in adults with amblyopia. Research participants will be asked to play video games with the amblyopic eye for a period of time. A range of visual functions will be monitored during the course of treatment. ;
