Figure 5.

When patients with tunnel vision make saccades larger than their full VFs over a stripe pattern, they never perceive jumping stripes, although the stripes are unlikely to fall on the same retinal position. When patients made a saccade from the left 4-dot pattern to the similar pattern on the right side in which one dot is 2° further away from the fixation mark, they never perceived a jumping dot. Two fixations are placed apart far enough (~24°) to ensure saccades larger than full VFs at a distance of 14 inches.
