title: Sorbitol metabolism in retina studied in vitro.
abstract: A new method is described which allows study of the retinal sorbitol metabolism in vitro. Bovine retinal tissue was incubated in tissue culture medium for 24 h and after this time showed only small morphological changes. The sorbitol content doubled at a glucose level of 5.5 mM compared with freshly prepared noncultured retina. Increasing glucose concentrations led to a gradual increase of the sorbitol content. Supplementation of the culture medium with fructose likewise enhanced the retinal sorbitol accumulation. An aldose reductase inhibitor (ICI 128436; Statil) significantly decreased the sorbitol content.
