The U.S. FDA has granted breakthrough device designation for Righteye LLC’s eye movement-tracking vision system as a test for Parkinson’s disease. Developed by researchers at PADRECC and Virginia Commonwealth University with funding from the Michael J. Fox Foundation, and licensed to Righteye in 2016, the test requires patients to sit in front of an all-in-one tablet-looking device and follow a series of moving targets. The goal is to identify ocular tremors, a persistent issue with Parkinson’s patients that prevents steady fixation on objects and images. The noninvasive test, which measures an individual’s ability to follow objects on a screen, could help doctors not only confirm the difficult-to-diagnose disease, but also detect it at earlier stages.
