Figure 6.

Examples of increasing FAZ with increasing foveal pit excavation. Foveal OCT scans (A, D, G), retinal thickness maps (B, E, H), and FAZ images (C, F, I) are shown for three subjects. Data from the left eye of a patient with albinism reveals that the absence of a foveal pit is associated with the absence of a FAZ (A–C). The data from this patient were not included in the present analysis but is shown to illustrate one extreme in how the FAZ and pit are related. In two healthy persons with extreme foveal pit morphology, the positive correlation between the size of the foveal pit and the size of the FAZ is captured (D–I). Scale bar, 100 μm.
