[Correlation between the metabolic follow-up and diabetic retinopathy].

The state of the fundus oculi was investigated in 40 insulin-dependent and 20 non-insulin dependent diabetics. In both groups the state of the fundus oculi was correlated with total cholesterol, LDL, HDL, glycosylated haemoglobin, platelet adhesiveness, triglycerides and duration of the disease. In the case of insulin-dependent diabetics a correlation was also sought with daily doses of insulin. The fundus oculi was normal in 21/40 insulin-dependent and 14/20 non-insulin-dependent subjects. Multiple regression showed a positive correlation between insulin-HbA doses and duration of the disease and the fundus oculi. Simple liner regression showed a negative correlation between insulin doses and fundus, a tendentially positive correlation between platelet adhesion and fundus. A positive correlation between LDL-platelet adhesion and fundus was also shown in the non-insulin-dependent subjects. These results suggest that factors held to influence macroangiopathy also have an effect on macroangiopathy, that the check up of diabetics is important for the prevention of retinopathy, that insulin doses should be strictly limited to the necessary amount for the control of diabetes since excess is as harmful as insufficiency.
