Impact of Eye Movements on Reach Performance
Aim 2 of Reaching with Central Field Loss
Reaching with Central Field Loss
Crowding increases with eccentricity, and is most readily observed in the periphery. During natural, active vision however, central vision plays an important role. Measures of critical distance to estimate crowding are difficult in central vision, as these distances are small. Any overlap of...
Walker et al (Renninger, Psomadakis, Dang & Fletcher, 2008) suggested a novel method to estimate the monocular scotoma area from perimetry data in macular degeneration based on (i) an optic-disc based estimation of the location of the fovea and (ii) the increase in the receptive field size with eccentricity. Here, Dr Walker and I introduce a new GUI that applies this method to data from the Optos OCT/SLO.
I completed my BS in Chemical Engineering at MIT and PhD in Vision Science at UC Berkeley. At Berkeley, I studied with Dr. Jitendra Malik using psychophysics to validate computer vision algorithms. During my postdoctoral training with Drs. Preeti Verghese and James Coughlan at Smith-Kettlewell, I developed a computational model of eye movements and continue to apply and develop these models to predict how changing eye movements can improve vision for people different retinal diseases. My most recent project examines the impact of central vision loss on eye-hand coordination. The ultimate goal is to take what is learned in the laboratory and translate it into low vision rehabilitation therapies.
