More proof that the eyes reflect overall health just arrived in the form of a study adding a disease to the list of what can be predicted by examining "the windows to the soul." Small changes in the blood vessels within our eyes at age 60 can foretell a significant loss of memory over the next couple of decades, suggests a study published in the medical journal Neurology. "We cannot see the very small blood vessels in the brain through standard brain imaging techniques" like magnetic resonance imaging, said lead study author Jennifer A.

Because blood vessels in the eye and brain are similar, Deal and her fellow researchers hypothesized that looking at blood vessels in the eye might explain what was happening in the brain.
