SINGAPORE: The eyes are said to be windows to the soul. Now, they are also peepholes into brain health, researchers at the Singapore Eye Research Institute (Seri) found.

Using non-invasive eye scans, the researchers have linked changes in the retina to what happens in the brains of patients with Alzheimer’s disease. Such changes can be detected in the early stages of the disease, when a patient is showing signs of mild cognitive impairment.
