Neurology of Vision and Visual Disorders

Jason Barton obtained his MD from the University of British Columbia in 1984, where he completed a neurology residency in 1990. He was a fellow in neuro-ophthalmology at the University of Iowa from 1990 to 1991 and the University of Toronto from 1991 to 1995, and obtained his PhD from the University of Toronto in 1996. He was assistant and then associate professor of neurology at Harvard Medical School, and director of neuro-ophthalmology at the Beth Israel Deaconess Medical Center from 1996 to 2004. Since 2004 he has been director of clinical neuro-ophthalmology at Vancouver General Hospital. He is currently professor, Canada Research Chair and Marianne Koerner Chair in Brain Diseases, in neurology, ophthalmology and visual sciences, and psychology at the University of British Columbia. His research is focused on cortical processing of vision, in particular high-level object perception, such as face and word recognition, and also on the use of saccadic eye movements to explore issues of cognitive control. I am Professor of Cognitive Neurology and a Consultant Neurologist at the UCL Queen Square Institute of Neurology. My main clinical and academic interest is in cognitive rehabilitation, especially in the field of acquired language disorders and vision. I am developing mechanistic accounts of how cognitive disorders can be improved by different types of therapy -mainly behavioural- using functional and structural brain imaging. I have developed three web-based rehabilitation tools that can be used to by therapists and patients with hemianopia or reading problems, and am working on four other electronic therapy projects sponsored by the MRC, NIHR and The Stroke Association. I think that web-based applications are a good way to make scientifically proven behavioural therapies available to suitable patients and their therapists. At the UCLH National Hospital for Neurology and Neurosurgery I have a specialist out-patient MDT assessment clinic for patients with hemianopia and/or higher disorders of vision. I also help run the Queen Square Intensive Comprehensive Aphasia Programme.
