Sensitive quantitative in vivo techniques were used to assess the permeability at the blood-retinal barrier (BRB) to [14C]sucrose in the anesthetized streptozocin-diabetic rat at various time points (3 wk, 6 mo, 13 mo) after induction of diabetes. The effects of concomitant administration of an aldose reductase inhibitor (ARI) on sorbitol levels in the retina and on BRB permeability were also measured. No increase in BRB permeability was found in rats diabetic for 3 wk or 6 mo, but after 13 mo of hyperglycemia there was an increase in permeability of 240%. No effect on permeability was seen in diabetic animals given the ARI despite the retinal sorbitol levels being decreased in the treated compared with the untreated diabetic group fed a normal diet. This study suggests that the accumulation of sorbitol within the cells of the BRB is not responsible for the breakdown of BRB permeability seen after 7-13 mo of hyperglycemia and that the enzyme aldose reductase is not involved in its pathogenesis.
