[The pathochemistry of the diabetic process in the eye based on data on experimental hyperglycemia (alloxan...

The paper describes results after a study of pathochemical disturbances of diabetic hyperglycemia on a model of alloxan diabetes. Sugar and amino nitrogen contents in the aqueous humor of the anterior chamber, anterior and posterior segments of the crystalline lens, the iris, ciliary body, choroid and the retina were studied and the data obtained were compared with quantitative contents of sugar and amino nitrogen in the eliminate from the eyes of experimental animals. High amounts of sugar and amino nitrogen, infrequently exceeding 2-3 times in controls, were found to appear in the aqueous humor of the anterior chamber, the crystalline lens, the vitreous body. In all tests the sugar and amino nitrogen contents in the posterior segment of the lens was 10-12% higher than in its anterior segment. The data obtained about accumulation of sugar and amino nitrogen mainly in tissues and media of the eye (the lens, the vitreous) affected by diabetic process already at its early stages widen the knowledge about pathogenesis of the process and peculiarities of its pathochemistry.
