Visual Pathways Inc. is a vision-care diagnostic company with headquarters in Prescott, Arizona. The company received a federal grant to develop a prototype of its GlucoScope™ Monitor, which measures glucose levels in the fluid of the anterior chamber of the eye, in 2003. The handheld device looks like a small pair of binoculars and uses infrared light to rapidly measure glucose levels in the eye. The federal funding was provided by National Medical Technology Testbed Inc. under the U.S. Department of the Army Medical Research Acquisition Activity.
On December 28, 2004 the U.S. Patent and Trademark Office awarded VPI U.S. patent 6,836,337 covering the GlucoScope™ Monitor. International patents covering the GlucoScope™ Monitor are pending. The monitor is currently in the research and development stage.
