Abstract
-
134 cases of Diabetes Mellitus were classified by the National Diabetes Data Group: Type I (Insulin dependent type), Type II (Noninsulin dependent type, II a: Obese type, II b: Konobese type). They were observed by fluorescein angiography and analysed according to variable factors such as sex, age, diabetic maculopathy, visual acuity and duration in each type of Diabetes Mellitus. The results were as follows: 1. Among 134 diabetic patients, incidence of diabetic retinopathy was 48%. Incidence of background retinopathy was 38% and proliferative retinopathy 10%. 2. Type I was more common in younger age, whereas Type II more in over middle age(p<0.05). 3. Diabetic maculopathy was more prevalent in Type II than Type I. 4. Diabetic retinopathy was prevalent in in worsened visual acuity(p<0.005). 5. Incidence of background retinopathy was found to be concerned with duration of Diabetes Mellitus not in Type I, but in Type II(p<0.05). 6. In proliferative retinopathy, duration of Diabetes Mellitus was shorter in Type I but longer in Type II(p<0.05).
