RightEye Introduces Eye-Tracking Tests to Help Diagnose Autism and Parkinson’s Disease



The RightEye Parkinson’s and Other Movement Disorders Test was developed by a team which included Dr. Mark Baron, professor of neurology, interim director of the VCU Parkinson’s and Movement Disorders Center and deputy director of the Southeast/Richmond Veteran’s Affairs Parkinson’s Disease Research, Education and Clinical Center at the Hunter Holmes McGuire VA Medical Center; Paul Wetzel, associate professor of biomedical engineering in the VCU School of Engineering and Dr. George Gitchel, associate director of research at the Southeast/Richmond PADRECC. This test was developed to accurately identify and assess patterns of eye movement that are affected in patients with movement disorders...

VCU Researchers Receive Michael J. Fox Grant to Study Parkinson's Disease

Richmond Times-Dispatch  online


The researchers — including Baron, Paul Wetzel and George Gitchel, also of VCU — have been working on the eye-tracking device for about 14 years. Initially, it was just a research interest, but soon Baron, Wetzel and Gitchel — who was a graduate student at the time and has since stayed on with the university — saw it as something more...

The Use of Eye Movements to Accurately Diagnose Combat-Related Mild TBI | Investigative Ophthalmology & Visual Science


Mild Traumatic Brain Injury (mTBI) is the signature injury of the current Middle East conflicts, most commonly occurring as a result of Improvised Explosive Device blast. Accurately diagnosing mTBI-related symptoms in service members with concomitant combat stress, pain, anxiety, and depressive disorders is challenging. Objective assessment of eye-movements represents a novel, efficient, and accurate means of discriminating the diagnosis of mTBI.
