[Nutrition metabolites in the anterior eye segments. Studies on model experiments and on man]

Glucose and fructose pathways of the cornea, the aqueous humour and the vitreous body were investigated under pathological conditions in the rabbit eye. There was a concentration gradient for glucose from blood via aqueous to corneal stroma and from corneal epithelium via corneal stroma to the aqueous. After experimental decrease of glucose by cyclodiathermy it is possible to increase glucose in corneal stroma by glucose or fructose infusions. Probably the sorbitol pathway plays a major role.
