The story quoted below identifies this as something "may someday" happen, but makes you wonder what else the eyes might someday tell us.
Seems that early research shows that a
simple eye test may help detect stroke risk:
A simple eye test may someday offer an effective way to identify patients who are at high risk for stroke, say researchers at the University of Zurich. They showed that a test called ocular pulse amplitude (OPA) can reliably detect carotid artery stenosis (CAS), a condition that clogs or blocks the arteries that feed the front part of the brain. It's a known risk factor for stroke. The OPA test could be performed by ophthalmologists – physicians who treat eye diseases – during routine exams. The study, which is published in the June issue of Ophthalmology, the journal of the American Academy of Ophthalmology, confirmed that patients who had the lowest OPA scores also had the most seriously blocked arteries.
So - someday, your eye doctor might indirectly save your brain.
