In a cohort of people without diabetes,the association of these retinopathy signs and subsequent development of diabetes were examined. Methods: A population based cohort study of 7992 people aged 49-73 years without diabetes was conducted. Retinal photographs of these participants were evaluated for the presence of retinopathy signs according to a standardised protocol. Incident cases of diabetes were identified prospectively. Results: After a follow up of 3 years,291 (3.6% ) people developed incident diabetes. In the total cohort,retinopathy was not significantly associated with incident diabetes (4.7% v 3.6% ,multivariable adjusted odds ratio (OR) 1.1,95% confidence intervals (CI),0.7 to 1.9). However,among participants with a positive family history of diabetes,retinopathy was associated with incident diabetes (10.4% v 4.8% ,multivariable adjusted OR 2.3,95% CI,1.0 to 5.3). Among participants without a family history of diabetes,retinopathy was not associated with incident diabetes Conclusions: In individuals with a family history of diabetes,retinopathy signs predict subsequent risk of clinical diabetes.展开更多
