Google has an AI algorithm that uses your eyes to predict heart disease

AI is the technological acronym of the moment, appearing tied to everything from smart speakers to smartphones. Scientists at Google’s health tech arm, Verily, however, have started using artificial intelligence to assess a person’s risk of developing heart disease.

Verily has developed an AI algorithm which is able to analyze scans of the back of a person’s eye and determine their age, blood pressure and whether or not they’re a smoker. Basically, all of the potential cardiovascular risk areas. Using this information, it’s then possible to assess someone’s risk of suffering a heart attack or developing heart disease. 

The researchers trained the algorithm using machine learning by having it analyze the eye scans and general medical data of around 300,000 patients. The AI was then able to gather patterns from this data and understand which signs in the eyes scans pointed towards cardiovascular risk.


In a paper published in the Nature journal Biomedical Engineering, the project researchers said that the method would have to be subject to further testing before it can be used in clinical settings.
