Fig. 4

Inter-rater segmentation variability (a) shows a high-resolution 30° line scan of a non-swollen optic nerve taken on the Heidelberg Spectralis OCT device. b shows a high-resolution 30° line scan of a swollen right eye optic nerve (papilledema) taken on the Heidelberg Spectralis OCT device. Both images also show independent segmentations of the ILM and BM done by 3 different raters (red, blue, green). The raters are generally in better agreement in segmenting the non-swollen optic nerve (a) when compared to the swollen optic nerve (b). Panel b shows the disagreement in ILM segmentation within the cup of the optic nerve due to a possible artifact. Panel b also shows that inconsistent identification of the medial margins of BM results in differences in the interpolated line connecting the left and right segments of BM
