Figure 3. Effect of timolol on oxidative stress-induced retinal ganglion cell damage

Following 24 h under AO- condition in the presence of timolol, the survival rate of RGC was assessed and normalized to that of the control AO+ condition. At 10 and 100 nM, timolol significantly increased retinal ganglion cell viability. Data are expressed as mean±SD, n=8. Asterisk indicates p<0.05; cross symbol indicates p<0.01 by Dunnet test.
