Melbourne researchers have developed a non-invasive, cost-effective eye test to detect early signs of Alzheimer's disease. The Centre for Eye Research Australia (CERA) will fast-track its research and begin clinical trials in August, after a $600,000 donation from a group of American philanthropists including Bill Gates and MacKenzie Bezos. The world-first eye scan trial will use technology like that used in NASA satellites, to look for abnormal proteins that build up in the brain through the retina. Peter van Wijngaarden from CERA said the new technology will test people who do not show any signs of memory impairment and detect abnormalities years before symptoms appear.
