Statistical analysis of GFAP and GS labeling fluorescence intensity. (A) Fluorescence intensity of GFAP labeling measured by ImageJ. No significant difference is observed between WT controls, KO control, and KO hypo specimens. Hypoperfused wildtype animals show a significantly higher fluorescence intensity compared to KO hypo specimens as well as the corresponding controls (P < 0.01; P < 0.05), respectively. Error bars SEM. (B) Fluorescence intensity of GS labeling measured by ImageJ. No significant difference in fluorescence intensity is found between WT control, KO control, and KO hypo specimens. Significantly lower fluorescence intensity is seen in hypoperfused wildtype retinas compared to the corresponding controls (P < 0.05). Error bars SEM. *P < 0.05; **P < 0.01; ***P < 0.001.
