Fig 6. Examples of manual expert segmentation (consistent and less consistent with each other).

Fig 6

Top: Repeatability of (a) expert 2 and (b) expert 5 when segmenting the CSI. Bottom: Comparison of segmentations by (c) experts 3, 4 and 5 and (d) experts 1, 3 and 4. The choroidal area is subdivided in nasal (N)-temporal (T)/x-direction into five equidistant regions (patches) symmetrically around the foveal center: A (foveal region), B (parafoveal region), and C (perifoveal region). Here only cases of right eyes are depicted.
