Figure 2.

Extraction of raw GCIPL thickness measurements from Cirrus OCT, with data from the same participant as Figure 1 shown. (A) Segmentation of retinal boundaries for the foveal B-scan as performed by OCT Segmentation software, with the boundaries of the GCIPL highlighted in yellow. (B) The resultant GCIPL thickness maps, from which averaged GCIPL thicknesses were extracted in microns (µm) over areas enclosed by the small circles. Circles that did not fall completely on the GCIPL thickness maps were excluded from further analyses. (C) Pattern deviation probability data superimposed onto the GCIPL thickness maps, depicting the corresponding VF and OCT locations compared in later analyses.
