PURPOSE We investigated the efficacy of intravitreal injections of anti-VEGF agents in a rat model of anterior ischemic optic neuropathy. METHODS We applied laser-induced photoactivation on the optic nerve head after intravenously administered rose bengal (RB). The rats immediately received an intravitreal injection of either ranibizumab or PBS. The density of retinal ganglion cells (RGCs) wa...
