Figure 6

Confocal microscopy of the retinoblastoma and retina at 24 hr after intravitreal injection of CY5-labeled NPs into the vitreous cavity of rat with retinoblastoma. (A–E) Control group; untreated retinoblastoma (A) and untreated retina (C). (E–H) Eyes injected with Cy5-labeled CMD-TCs-NPs. The Cy5-labeled CMD-TCs-NPs diffused to the tumor mass (F) and through the retinal layers (H). (I–L) Eyes injected with Cy5-labeled CMD-TMC-NPs. Cy5-labeled CMD-TMC-NPs are entirely trapped in the vitreous and are not able to reach the retina even after 24 hr.
