Examples of the extreme positions of the patient’s eye and the results obtained. The images from a to f are the subsequent positions of the left eye: starting with the central position, then down, right, up, left and back to the central position. g A sample graph of stimulus brightness changes (red) from 0 to 220 mcd for the position changes of the perimeter by the angle of 35° (green background), 40° (yellow background), 55°, 60° and 60° (red background) as well as −60° (blue background). The changes over time of the angular displacement of the left eye are marked in blue
