Figure 7. Density of Iba-1 positive (Iba-1+) retinal microglial cells in each of the experimental groups as well as in a group of naïve control eyes.

Microglial cell density was elevated 4 weeks after ONT, whether CTB was present or not, but also substantially elevated in ONT-fellow eyes only if CTB was present. *One-way ANOVA with Bonferroni post-hoc tests (p<0.05). Error bars indicate SEM.
