Scottish researchers are set to explore how a simple eye test could be used to detect early signs of dementia.
Working in collaboration with the University of Edinburgh, a team from the University of Dundee has developed software, which analyses high definition images of the eye, looking for physiological changes which may be associated with Alzheimer’s disease.
The software will be used to analyse thousands of images, along with medical histories, and measure a number of small changes in ocular blood vessels – such as length, width, thickness and angle of branching – which might indicate important changes in the brain, but which would be too time intensive to record by hand.
Project coordinator Emanuel Trucco, a Professor of computational vision said the research showed “the promise of early warning in a non-invasive way”.
He said the test could also possibly differentiate between different types of dementia.
