Eyeglass-Mounted Device Could Diagnose Dangerous Diabetic Condition

Eyeglass-Mounted Device Could Diagnose Dangerous Diabetic Condition
Jul-31-14
A new eyeglass-mounted device able to detect a common diabetes-related neurological complication could lead to earlier diagnoses—and therefore earlier treatment—of the condition.

Doctors usually watch for diabetic automatic neuropathy by monitoring changes in the patient's blood pressure, heart rate and digestive speed, but this method does not allow for an early diagnosis. To speed up the process, a research team from the National Taiwan University Hospital and National Chiao-Tung University in Taiwan created an optical sensor called a pupillometer that hangs from a pair of eyeglasses and monitors the wearer's pupils. The device needs to be worn for only about 30 minutes, during which time it shines colored LED lights to stimulate the pupil. As the pupil changes size in response to the light, an integrated beam splitter filters the reflected light to the device's camera for image processing and analysis.

The pupillometer measures ten parameters relating to pupil response-time, and five of those parameters have been shown to be quite different in subjects who have diabetic automatic neuropathy.
