Overview
Research in my lab is focused on exposing the mechanisms underlying disorders of visual perception – including blindsight, Charles Bonnet Syndrome (hallucinations), visual dyslexia and infantile nystagmus. In particular, I am interested in the role of involuntary eye movements in perceptual (in)stability. My interest in eyetracking extends to the clinical application of eyetrackers in routine eyecare and neurology practice. I am the author of the popular ophthalmology e-textbook Dunn Vision Reference.
We typically recruit patients with orthoptic or perceptual disorders in order to better understand visual physiology. If you have a neurological visual disorder and are interested in taking part in research, please click here for more information.
