Figure 1. Retinal ganglion cell viability of seven experiments under (A) glutamate-induced neurotoxicity, (B) oxidative stress, and (C) hypoxic stress, with increasing concentrations of brimonidine. Brimonidine at a concentration of 1 μM significantly increased retinal ganglion cell (RGC) viability in all three stresses. Abbreviations: (-) represents control RGC cultures without glutamate; (+) represents control RGC cultures with glutamate, AO(+)represents medium with anti-oxidant; AO(-) represents medium without anti-oxidant, * represents p<0.01. n=7. Error bar indicates SD.
