Eye tracking to diagnose stroke: study

A simple, inexpensive way to diagnose life-threatening stroke has been developed by a team from Johns Hopkins University School of Medicine. Their device–special goggles wired to a laptop with new software–is able to differentiate key eye movements that are indicative of stroke versus other conditions such as inner ear infections. The goggles (made by GN Otometrics for balance conditions) combine a USB-connected webcam and an accelerometer in the frame to track the eyeballs, while a clinician performs head impulse testing (rotating the patient’s head while he looks at a stationary object); the software interprets the subtle signs that “directly predict” stroke. The researchers dub the technique as “ECG for the eyes.” Now put this into a tablet or smartphone….  Medgadget   Johns Hopkins Medicine release
