The easiest way to locate the central point is to use the Cursor
method. Move the cursor with the glidepad or finger on the touch
screen to the desired location. In this example, the cursor is positioned
to run the Scotoma Map from a point centered at Meridian: 200 and
Radius: 15. Skip to Step 5.

seen for a short time and then it will move into the patient’s field of
vision. Ask the patient to press the response button as soon as he or
