Figure 2: Serial horizontal OCT scans of the left eye through the RPE detachments illustrating their natural history
Three dome-shaped RPE detachments were found, 1,670 µm from the fovea at 9 o’clock (left panels), 3,200 µm from the fovea at 10:30 o’clock (middle panel), and 750 µm from the fovea at 2 o’clock (right panel). The images were taken at the baseline, as well as after one, two, three, four and seven years of follow-up (from top to bottom, respectively). All the PEDs had round basis with diameters ranging from 498 to 593 µm (left panel), 423 to 486 µm (middle panel) and 1,144 to 1,225 µm (right panel). The height of the elevations varied, reflecting their flattening and complete resolution, and ranged from minimal to 63 µm (left panel), minimal to 135 µm (middle panel) and 106 to 235 µm (right panel). The presence of the detachments was not associated with fluid accumulation between RPE and neurosensory retina. The RPE layer within the detachment was continuous and showed no defects. The thickness, structure and foveal contour of the overlying retina were normal.
