[The type of the diabetic retinopathy and the clinical picture of diabetes mellitus (author's transl)].

There are two groups of diabetics under report, group I comprising 70 cases of retinopathia simplex, group II 100 cases of retinopathia proliferans in the centre. Retinopathy, showing as first sign of angiopathy, offers a comparatively good prognosis for the overall case of diabetes since, normally, neither retinopathia proliferans nor glomerulosclerosis are apt to develop. The same, in a higher degree, applies to cases of simple retinopathy fully devoloped and verified through ten years, at least: Retinopathy then shows stationary, in fact regressive development, the attending nephropathy generally expressing itself by the benign form of pyelonephritis and arteriolosclerosis renum rather than by glomerulosclerosis. All this in sharp contrast to proliferating retinopathy. Coronary sclerosis, peripheral and cerebral sclerosis and, to a limited extent, arterial hypertension stand independent of that; they attract attention by noteworthy independence.
