The retina holds a huge amount of medical information about your health and risk of cardiovascular and metabolic disease. Despite this, most doctors have no simple way of using this information to help reduce these risks. Corax Medical has developed an easy-to-use, inexpensive optical device that gives accurate data to doctors. The device helps diagnose risks of heart disease, stroke, and complications from diabetes, and provides non-invasive, rapid assessment for patients in the emergency department. It enables more effcient and effective assessment, and yields evidence to base accurate dosing of medications.
