An Active Approach to Treat Amblyopia: Perceptual Learning and Video Games

Amblyopia Clinical Trial

Official title: Improving Spatial and Temporal Vision in Adult and Juvenile 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 both adults and children 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 both normal and amblyopic spatial vision. This study uses psychophysical measures to study neural plasticity in both adults and children with amblyopia. Research participants will be asked to practice a visual discrimination task (perceptual learning) or 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. ;
