Figure 5

Retinal Microglia density graphs. (a) shows a graph of the total microglia density per pixel per retina with ageing. There were no significant differences between each age group (Kruskal Wallis). (b) shows a graph of the individual microglia morphotypes in the ageing retina. These were expressed as the percentage of each morphotype cells per retina. There were significant differences in the activated and rod microglia. (c) A graph of the PA microglia morphotypes in the ageing retina with the percentage of cells per retina for each morphotype. There were significant differences in the PA activated microglia with increasing age. (**p < 0.01, *p < 0.05, 2-way ANOVA with multiple comparisons). Black = 2 m; Pink = 6 m; Blue = 28 m.
