Diabetic Retinopathy (DR) is one of the leading causes of blindness in the world . In USA it is the most important cause of blindness in the 20-74 years age group. Recent medical treatment and surgery can reduce the rate of blindness up to 90% . The most important causes of blindness in diabetic retinopathy include , macular ischemia , macular edema , neovascularization on the disk , retina or iris.We donʹt know the exact frequency of DR and it causes in our population . The aim of this study , was to determine patients at risk and early treatment to reduce costs and visual complications . A cross - sectional study was performed between Oct. 2000 and July 2001 on diabetic type!! patients who were referred to the yazd Diabetic center . Dilation of the pupil by a midriatic droplet indirect ophthalmoscopic examination and in some cases a +90 lens or a 3 mirror were used for examination of macula . Patients were divided into 6 groups according to the clinical findings : 0) Without retinopathy . I) Mild non-proliferative retinopathy (NPR). [1) Moderate NPR. III ) severe NPR . IV) proliferative retinopathy and V) Proliferative retinopathy with complications such as vitreous haemorrage or deculman . LIME was also recorded . Data wase collected and results were statistically analysed by X2 using spss for windows . A total of 590 NIDDM patients were examined of which , 358 patients (60.7%) had no any signs of retinopathy . One hundre and thirteen patients ( 19.3%) had mild NPR , 71 patients (12%) moderate NPR , 16 patients (12.7`%) severe NPR 18 patients (3.1%) , PDR without complications , and 14 patients ( 2 . 4 % ) PDR plus complications . In other words, 39.3% patients had diabetic retinopathy . The frequency of diabetes in our province is considerably higher than the rest of the world (14 % VS 3 % ) and its occular complications are also higher ( 39.3% in Yazd vs world 25%).We concluded that age , BMI , blood sugar level & glycolised hemoglobin levels are importimt risk factors for occular complications in diabetics .
