[Systemic diseases in patients with cataract-extraction (author's transl)].

214 patients who underwent cataract-extraction in 1973 were examined for systemic diseases. The average age of patients with (70%) and without (30%) general diseases was 67 years. The frequency of cardio-vascular and respiratory diseases corresponded to that observed in the general population of the same age. In contrast, the rate of diabetes mellitus was four times higher than to be expected statistically. The importance of an adequate clinical management of diabetic cataract patients is discussed.
