Impact of macular sparing versus splitting on reading. (Top) Scan path from a patient with a left hemianopia and 3–4° of macular sparing. He read 366 words per minute, advancing 8.6 characters (including spaces) per saccade. The scan path is shown in Supplemental Video 1. (Bottom) Scan path from the patient illustrated in Figure 9 with a left hemianopia and macular splitting. He read 193 words per minute, advancing 4.7 characters (including spaces) per saccade. He tended to overshoot the left text border. Mean fixation durations were similar (217 ms versus 195 ms). The scan path is shown in Supplemental Video 2.
