Mapping residual visual function in hemianopia

Cardiff University Logo

This study is investigating the vision that remains in people with homonymous visual field defects (HVFD). A HVFD is a deficit that results in a person not being able to see on one side. Specifically, we are investigating something called ‘macular sparing’, where some vision on the blind side (close to the centre) remains. It is not clear why some vision is spared. One explanation is that some important parts of the brain are left undamaged. An alternative explanation is that the spared vision does not really exist, it just appears to exist because of the way your vision is normally measured. We hope to work out which explanation is correct using a combination of vision testing and brain imaging. For more information or to sign up to the study, please contact Mason Wells.
