BOSTON - Looking deep into someone's eyes may reveal they have Parkinson's disease years before they develop the telltale symptoms.
You may have heard that the eye is a "window" to the rest of the body because looking at the back of the eye can reveal signs of certain conditions like high blood pressure and diabetes. High-definition retinal scans have also been used to identify signs of neurodegenerative diseases like Alzheimer's, multiple sclerosis, and schizophrenia.
Now with the help of artificial intelligence, researchers at the University College London have pinpointed markers of Parkinson's disease in these images that may be present an average of seven years before patients even develop symptoms. While they can't yet predict who will develop Parkinson's, this method could one day become a pre-screening tool for those at risk.
