Fig. 5.

En face optical coherence tomography angiography image of the radial peripapillary capillaries of the retinal nerve fiber layer (RNFL) of the right (A) and left (D) eye demonstrate a reduction in peripapillary perfusion in the left eye compared to the right. Vessel skeleton maps and vessel area density maps of the peripapillary vasculature of the right (B, C) and left (E, F) eye demonstrate decreased vessel density in the left eye compared to the right, consistent with glaucomatous damage in the left eye. B-scan of the left eye (G) at the location demarcated by the yellow horizontal line in D demonstrates thickening in the region of the RNFL (due to gliosis) in regions of poor perfusion.
