[Retinopathia diabetica proliferans in various age (author's transl)]

Interrelations between the process of growing old and diabetic proliferative retinopathy are investigated with 45 patients, arranged in two groups, group I (21 cases) comprising patients of 20 to 30 years of age, group II (24 cases) patients 50 to 60 years. Inner structures and certain conditions of retinopathy prove to remain untouched, only the appearance is diminishing during the process of growing old. All this is reflected by the attendant nephropathy and the other forms of angiopathy. Behind it there are the multifarious symptoms of aging, contingent chiefly on the changing endocrine and the early developing of vascular "old-age sclerosis".
