Figure 4.
Horizontal SD-OCT scans (A-H) and corresponding near-infrared fundus autofluorescence (NIR-AF) in P57, P23, P19, P48 and P22. The red lines (horizontal in the SD-OCT images and vertical (horizontal) in the fundus images) mark the zone where the ellipsoid zone (EZ) and RPE/Bruch’s bands are intact. The blue lines demarcate the zones where the EZ band is absent. The horizontal lines in A-H are placed below the reflectivity bands attributable to RPE/Bruch’s membrane in the SD-OCT images. Within the zones indicated by the blue lines, reduced pigmentation is apparent in color fundus, NIR-R and NIR-AF images. The latter aberration is more pronounced in the zones peripheral to the blue lines.
