Visual Surveillance of Extremities

Visual Surveillance of Extremities, also known as VSE, is Thomas Covenant's practice of periodically examining his body for injury. The practice was taught to him by the doctors at the Leprasorium, as a way to compensate for the loss of sensation resulting from by the nerve damage caused by his leprosy. Because Covenant can't feel the pain from small injuries, he runs the risk of not noticing them and allowing them to fester and aggravate his disease.
