Post-treatment with Pt NPs protected the structure of light-induced retina. (A) H&E staining images of the retina for each group. (B) Enlarged view of the region inside the black box in (A). (C) Enlarged view of the region inside the red box in (A). (D) The statistics of ONL, IS, OS and RGC for each group. LIRD mice that post-treated with vehicle were named as vehicle. Data are expressed as the mean ± SD, n ≧ 10. One-way ANOVA were used for comparisons with vehicle. ****p < 0.0001; ***p < 0.001; **p < 0.01; *p < 0.05. RGC, retinal ganglion cell layer. ONL, outer nuclear layer. IS, inner segment of the photoreceptors. OS, outer segment of the photoreceptors. LIRD, light-induced retinal degeneration.
