RGC density results.

<p>(A) Representative retinal whole-mount images (450 x 320 μm, 850 μm from the center of the optic nerve head, 20x magnification) with Brn3a-labeled RGCs from both eyes in all groups. (B) Average RGC density in all groups. (C) The relative difference in RGC density between eyes for all groups. ** p < 0.01, mean ± SD, n = 9 in the laser group, n = 8 in the acute suture group, n = 11 in the chronic suture group, n = 12 in the chronic suture 28-day group.
