Fig 6. ORTs viewed en face on SD-OCT are contiguous with central regions of preserved retina.

Fig 6

Four sets of SD-OCT en face and B-scan images are presented here for subjects JC_0621, JC_0699, JC_0754, and JC_0942. En face projections are aligned to averaged line scans passing horizontally (bottom) and vertically (right) through the fovea. Orthogonal lines on each en face OCT indicates the locations at which line scans were taken. B-scan cross sections of ORTs can be seen as distinct hyperreflective ovaloid structures superficial to Bruch’s membrane; in en face projection, ORTs appear as long, thin protrusions. Most ORTs are contiguous with the central region of preserved retina, though remnant “island” ORTs can also be seen amidst surrounding atrophy. Scale bars: all lateral & en face OCTs (L/E) = 1,000 μm, axial OCTs = 200 μm.
