Figure 2. Expressions of RVO-related genes after timolol eye drops in the retina of RVO mice. Expression levels of Vegf, Atf4, Il6, and Tnf-α in the occluded retinas after topical administration of timolol maleate. Results are presented as mean ± SEM (n = 5, 6). *p<0.05, **p<0.01 versus vehicle, ^##p<0.01 versus control (Tukey’s test).
