What happens during the test? icon plus
Your consultant physiologist will explain the diagnostic test to you. Your eyesight will be checked and you'll be asked to read an eye chart. Electrodes will be attached to your head using sticky paste. One of your eyes will be covered with an eye patch. You'll see a TV screen with a moving pattern of black and squares displayed on it you'll be asked to focus on this for a few minutes. The physiologist will record the movements of your eye as you watch the screen. Each eye is tested. The test takes about 30 minutes to one hour. -
