Motion Perception in Central Field Loss

The project investigates motion perception in individuals with vision loss due to central retinal lesion, but who retain healthy peripheral retina. Healthy peripheral retina is exquisitely sensitive to fast speeds, however, there is limited and conflicting information about motion processing in residual peripheral retina in patients with central field loss, often due to macular degeneration. We use psychophysical and eye tracking approaches to systematically probe speed and direction sensitivity in this  population.
