  • Patent number: 7988288
    Abstract: A method of ocular testing is provided using a testing apparatus having a display (2) and a control means (6, 17) for controlling movement of a cursor (7). The method comprises providing a fixation target (T), detecting when an observer (1) moves the cursor (7) over the fixation target, and once the cursor has been moved over, providing a new target on the display (2). The observer (1) is then encouraged to move the cursor (7) over the new target, this then becoming the fixation target. If the observer (1) does not move the cursor (7) over the new target, it is determined that the new target falls outside the observer's visual field. The above is then repeated to build up a visual field of the observer (1) based on the detected and undetected target positions.
