Figure 7. Nanoceria (1–1000 uM) had no negative effects on retinal morphology, even four months after injection, as measured by quantitative morphometric analyses.

We examined the central (A–B), and peripheral (C–D) portions of the retina of animals from different treatment groups (UI = uninjected, Sal = saline injected, or CeNP injected with the indicated dosage), and found no changes induced by nanoceria. Measurements were performed as indicated in Figure 4.
