title: [Morbidity and mortality in type 1 and type 2 diabetes mellitus after the diagnosis of diabetic retinopathy].
abstract: One to ten years after laser coagulation for diabetic retinopathy, 229 type I diabetics (mean age 44.3 years) and 157 type II diabetics (mean age 65 years) were re-studied for morbidity and mortality (progression of late damage, duration of survival, cause of death). The duration of diabetes at the first laser coagulation averaged 23.1 years for type I diabetics (15.9 years for type II). Average period from the first laser coagulation to the re-examination was 6.5 years for type I, 5.1 for type II diabetics. Of those patients still alive 6.7% had gone blind (type II: 7.3%). 2.1% and 4.6%, respectively, were receiving dialysis treatment, while renal transplantation had been performed in 3.1 and 1.8%, respectively. Stroke was the most frequent macrovascular complications (8.4 and 16.5%), followed by leg amputation (3.6 and 14.7%) and myocardial infarction (3.7 and 18.3%). 83 patients had died: 35 (15.3%) type I and 48 (30.6%) type II diabetics. Causes of death were septicaemia 14.3% (0%), uraemia 11.4% (8.3%), myocardial infarction 14.3% (33.3%), heart failure 8.6% (29.2%) and stroke 5.7% (6.3%). 10.7% (24.2%) had died within the first 5 years after laser coagulation. Despite a lower incidence of blindness in patients with diabetic retinopathy, the vascular disease progresses in other vascular regions so that a large proportion of diabetics will develop renal failure or die early from macrovascular complications.
