Figure 5.

(a) Expected/calculated and (b) actually measured slices through the volume visual fields (at distances of 50, 100, and 200cm) for Patient 1 (bitemporal hemianopia). Two different fixation distances were used to map the anterior (left) and posterior (right) volume scotomas, respectively, as shown in (a). The visual fields that were not measured at the given fixation distances are shown in lower contrast in (a). The circular boundaries in (a) represent the liquid crystal shutter goggles’ restriction of the dichoptic perimeter.
