Research project called AlzEye uses the eye as a window for detecting the health of other organs.
Database of eye scans was collected, which offers a detailed picture of the health of the retina.
Data set includes over 300,000 patients scans who visited Moorfields between 2008 and 2018.
Doctors focused the project on dementia and the data includes 15,100 cases.
Patterns in the eye that betray the emergence of the disease will be detected with machine-learning algorithms.
Further searches are planned for patterns related to strokes and heart disease.
