• Vitreous fluorophotometry was used to evaluate the integrity of the bloodretinal barrier to fluorescein in hooded rats. Streptozotocin-induced diabetes mellitus caused a breakdown of this barrier within ten days. Normalization of blood glucose levels with insulin significantly reduced (P <.005) the increased permeability. This functional microangiopathy might prove to be the earliest detectable change in the retinal circulation in experimental diabetes.
