Eye Photography May Reveal Stroke Risk, Study Finds
Posted by Neill Abayon
Your eyes may provide a window into your risk for a stroke, a new study suggests.
By photographing the retina, researchers say they can predict the potential for stroke in people with high blood pressure.
"High blood pressure is one of the most important factors involved in the development of stroke," said lead researcher Dr. Mohammad Kamran Ikram, an assistant professor at the Singapore Eye Research Institute of the National University of Singapore. But determining which hypertensive patients face the highest risk of stroke isn't possible.
Now, a simple eye examination may provide that information, Ikram said. He said, however, that other studies are needed to confirm the findings, which were published Aug. 12 in the journal Hypertension.
High blood pressure can damage blood vessels in the retina. When that happens, the condition is known as hypertensive retinopathy. Retinal imaging is a non-invasive way to view blood vessel damage and possibly assess risk for stroke, a leading killer of Americans.
