H&E. A, B Retinal thickness was comparable between control eyes (A) and CTE eyes (B); scale bar = 40 μm. C Quantification of retinal thickness in number of nuclei by layer, 1 mm (GCL1, INL1, ONL1) or 2 mm (GCL2, INL2, ONL2) from the optic nerve toward both equators per retina, in CTE (n = 6–7) and control eyes (n = 7). Error bars show mean ± standard errors. Student’s t-test comparisons of means between CTE and controls are shown, and p < 0.05 was considered statistically significant. RNFL, retinal nerve fiber layer, GCL, ganglion cell layer, IPL, inner plexiform layer, INL, inner nuclear layer, OPL, outer plexiform layer, ONL, outer nuclear layer
