Eye tracking helps spot movement disorder
Tobii Technology (Danderyd, Sweden) has selected a behavioral research team that used eye-tracking technology to enhance its understanding of Progressive Supranuclear Palsy (PSP) as the winner of its annual Tobii EyeTrack Award.
PSP is a degenerative disease that occurs from damage to certain nerve cells in the brain which is often misdiagnosed as Parkinson's disease. Many areas of the brain are affected, including the part of the brainstem where cells that control eye movement are located.
The winning team of researchers, led by Susana Martinez-Conde from the Barrow Neurological Institute (Phoenix, AZ, USA), used Tobii Technology’s eye tracking system to study and characterize eye movement abnormalities in individuals with PSP.
"We hope that our research will enable PSP to be diagnosed earlier and provide insights into the pathogenesis of this devastating disorder," said researcher Martinez-Conde.
The researchers' study into the disease -- entitled "Distinctive Features of Saccadic Intrusions and Microsaccades in Progressive Supranuclear Palsy" -- is available here.
The award will be presented to the researchers at the company's annual EyeTrack Behavior Conference in Leuven, Belgium between October 9-10, 2012.
