Figure 7

NCO point cloud (top) generated from the SD-OCT volume of the left eye of monkey 25904, a 1-year-old female rhesus macaque. Middle: RPE/BM complex delineated by orange lines. The NCO points relative to their fitted plane viewed from temporal to the disc, (OD configuration, superior left and inferior right) are depicted below. Bottom: NCO plane error (defined as the average of the shortest distance to the plane for each NCO point) is 18 μm. Unlike in Figure 6, in this eye, the NCO points are clearly contiguous suggesting a gently bowed structure that is symmetrical about the vertical axis. Although method error still contributes to plane error in this eye, biological nonplanarity is most likely the principal component. Biological nonplanarity that is delineated reproducibly over time will still provide a stable fitted plane for a zero reference.
