SiO2 NPs decrease the number of retinal cells. PBS or 15-nm SiO2 NPs were injected into the right eyes of rats. After euthanization, retinal sections were prepared for fluorescence microscopy. At 1 d (A), 7 d (B), and 14 d (C) after injection, the retinal layers (INL, GCL, and RGC layers) were stained by DAPI, and the cells in each layer were counted. Representative images are shown in the left panel, and the bar graph depicts the mean percentages of dead cells. *p < 0.05 compared to the vehicle control. Scale bar: 100 μm
