Figure 4. Comparison of the number of peaks of plot profile between AO-on images and AO-off images.

Figure 4

A, B. AO-on image focused on the RNFL. Mean gray value of images was plotted (190 pixel width) along a line that vertically crosses the hyper-reflective bundles. C. Plot profile of gray value along the yellow line of B. The number of peaks, which was defined as more than 20 gray values compared to the neighboring baseline, was 8. D, E. AO-off image of same area. F. Plot profile of gray value along the yellow line of E. The number of peaks was zero.
