In general glucose concentration in the aqueous is similar to concentrations in the plasma. From the Biochemistry of the lens 31 Fig. 8: Oxidative damage of lens (by free radicals) aqueous glucose diffuses rapidly into the lens. The lens metabolizes glucose through the four main pathways as already mentioned in this chamber. In diabetes excessive glucose in the lens (more than 200 mg/100 ml) saturates hexokinase. Excessive glycosylation of lens proteins takes place and glucose is converted to sorbitol by auto-oxidation and protein binding (aldose reductase).
