Permeability of blood-ocular barriers of neonatal and adult cats to fluorescein-labeled dextrans of selected molecular sizes.

摘要: The permeability of the ocular blood vessels and neuroepithelial layers (the blood-ocular barriers) to fluorescein-labeled dextrans selected molecular sizes was evaluated in neonatal adult cats by fluorescence microscopy. iris ciliary process were permeable molecules as large 85A effective diffusion radius (EDR). In kitten, choriocapillaris 58A EDR, only 32A EDR. retinal pigment epithelium impermeable all markers. role cat's vessel aqueous humor formation appears dissimilar that other species larger than serum proteins traverse walls capillaries.
