Method, software and apparatus for testing a patient's visual field

A non-transitory computer readable medium having instructions for implementing a method for testing a patient's visual field using testing apparatus, the software program comprising:

• (a) instructions for providing a fixation target on a display at a known target position;
• (b) instructions for tracking the patient's direction of gaze using an eye tracker to determine the patient's point of regard on the display;
• (c) instructions for providing a marker on the display indicating the patient's point of regard, where the marker moves with movement of the patient's point of regard;
• (d) instructions for detecting when the marker is moved to the fixation target;
• (e) instructions for providing a new target on the display at a further known target position once the marker is moved to the fixation target;
• (f) instructions for recording the new target as detected if the marker is moved to the new target, the new target then becoming the fixation target;
• (g) instructions for repeating instructions (e) and (f) for further new targets a further known target positions for determining the patient's visual field based on the positions of the new targets that have been detected.

Apparatus for testing a patient's visual field, the apparatus comprising:

• a display;
• an eye tracker for tracking the patient's direction of gaze to determine the patient's point of regard on the display;
• a control unit configured to (a) present a fixation target on the display at a known target position;
• (b) present a marker on the display indicating the patient's point of regard, where the marker moves with movement of the patient's point of regard;
• and (c) present a new target on the display at a further known target position once the marker is moved to the fixation target;
• a memory for recording the new target as detected if the marker is moved to the new target, the new target then becoming the fixation target;
• wherein the control unit is further configured to present further new targets at further known target positions and the memory is for recording if the further new targets are detected for determining the patient's visual field based on the positions of the new targets that have been detected.
