Researchers at Glasgow Caledonian University have collected a million eye scans from opticians across Scotland, and say digital health projects of its kind could save the NHS £37mil a year.

Researchers in Scotland are developing a digital tool powered by artificial intelligence that can gauge your risk of developing dementia simply by scanning your eyes.

Opticians, now more often called optometrists, will be able to use the software subsequently developed as a predictive or diagnostic tool for conditions such as Alzheimer’s, as a triage tool to refer patients to secondary health services if signs of brain disease are spotted, and potentially as a way to monitor cognitive decline.

Researchers are working with high street opticians to develop a digital tool that can predict a person’s risk of dementia from an eye test.

Scottish scientists from the NeurEye research team have found that photographs taken of the retina at the back of the eye can indicate of brain health. It is done using AI software to analyze the information.
