Retinal cross sections imaged by light microscopy of the eyes harvested from a rabbit 3 months (R83) and another rabbit 6 months (R32) after intravitreal injection of DNR-loaded hydrosilylated porous Si particles (taken at 62.5×magnification). Images show a normal retina and choroid in pairs of 2 eyes of the same rabbit. The left eyes (OS) were the control eyes and the right eyes (OD) were the study eyes injected with DNR-loaded pSi particles.
