Dynamic Visual Acuity is a common functional assessment of the VOR - You may have come across it in clinical practice using a Snellen chart. In this video you will learn about using a computerized system to improve accuracy, repeatability and objectivity. Darren Whelan will describe how to prepare your patient as well as how to perform the test in a variety of ways – including passive and active movement of the patient. He will also describe two methods to collect the patient response; allowing them to press buttons themselves or having them call out their response so the clinician can mark it in the software.
