Dense scotoma mapping by microperimetry, SW-AF, and OCT findings at baseline and 24 months. Empty red squares indicate sites of dense scotoma. Solid red squares indicate that the brightest stimulus was seen. Other stimuli of lower intensity (indicated by colors other than red) were used in a few locations to measure the level of retinal sensitivity. The dense scotoma exceeded the standard 10-2 field, so that dense scotoma mapping was necessary to delineate the edge of the scotoma. (A) At baseline, fixation (small blue dots) was not stable, but was placed at the edge of the dense scotoma. (B) The microperimetry is overlaid on the SW-AF image. There is a mottled background pattern present. The dense scotoma greatly exceeds the dark lesion, and there are no particular features delineating the seeing from the nonseeing retinal areas. (C) The OCT scan was entirely within the nonseeing area and it was abnormal throughout. (D) At 24 months, the dense scotoma has enlarged. The fixation site is now remote from the edge of the dense scotoma. (E) At 24 months, the SW-AF image shows that the dark lesion has enlarged somewhat, but most of the mottled area remains unchanged in appearance.
