A method for testing a patients (2) visual field using testing apparatus. A fixation target is provided on a display (3) at a known target position and the patients (2) direction of gaze is tracked using an eye tracker to determine the patients point of regard. A marker (5) is provided on the display (3) indicating the patients (2) point of regard, where the marker (5) moves with movement of the patients (2) point of regard. It is detected when the marker (5) is moved to the fixation target and a new target is then provided on the display at a further known target position. The new target is recorded as detected if the marker (5) is moved to the new target, with the new target then becoming the fixation target. The steps are repeated for further new targets for determining the patients (2) visual field based on the positions of the new targets that have been detected.
