Figure 6 Hoechst staining of SI-induced ocular damage at the level of choroid, RPE and PR layers in sclerochoroid/RPE/retina whole mounts. SI (50 mg/kg, i.p.)-induced retina degeneration in BALB/C mice results in PR rosettes (arrows) and RPE nuclei (boxed areas). Higher magnification of RPE nuclei in the boxed areas are shown in the inserts. Scale bar: 50 μm. RPE, retina pigment epithelium; SI, sodium iodate; PR, photoreceptor.
