Figure 5

GVF 13 (31 isopter misses). The two small V-4e seeing areas in the inferior portion of the left hemifield were missed 12 (superior isopter, ~27° inferior-nasal from fixation, along the 225° meridian) and 15 (inferior isopter, ~45° inferior-nasal from fixation, along the 240° meridian) times. These very small isopters likely blended with the markings of the GVF sheet and the operator’s markings. Except for Digitizer 6, who only missed the superior left V-4e seeing isopter, all other isopter misses for this field were also accompanied by missing the inferior left V-4e seeing isopter. The top-left inset, provided for clarity and covers no isopters, shows a 200% magnified view of the central 20°.
