Figure 5. Nanoceria do not cause vascular permeability or leakage. Fundoscopic and fluorescein angiographic images taken at the PI7 day and the PI30 day show that the eyes from the vldlr^−/− mice exhibit an abnormal appearance of the fundus and have typical neovascularization and vascular leakage. None of the nanoceria- and saline-injected groups showed neovascularization or leakage and were similar to the uninjected mice. A representative image from each group is shown. n = 4–6 eyes per group.
