Mechanism of action

By binding to VEGF, bevacizumab prevents the growth and proliferation of pathological neovascular tissue that characterizes conditions like wet age-related macular degeneration and diabetic retinopathy. When injected directly into the vitreous cavity, it reaches high local concentrations to suppress retinal and choroidal neovascularization, reducing fluid leakage and vision loss.
