Introduction. Little is known about the relationship between insulin resistance and proliferative diabetic retinopathy in type 1 diabetes. The aim of this article is to explore the relationship between sight-threatening proliferative diabetic retinopathy and insulin resistance.Methods. This was a cross-sectional study that included 167 type 1 diabetes patients. Insulin resistance was assessed using eGDR (estimated glucose disposal rate) formula. Diabetic retinopathy was assessed by ophthalmoscopy using Early Treatment Diabetic Retinopathy classification. The association between eGDR and proliferative diabetic retinopathy was assessed in uni- and multivariate models using stepwise logistic regression of covariates. The contribution of individual predictors in the final regresion model was examined using Wald statistic.Results. Significantly lower eGDR’s values were observed in patients with proliferative diabetic retinopathy: 5.5 vs. 7 (p = 0.002). The results remained significant (p < 0.001) after adjusting for multiple covariates (sex, diabetes duration, body mass index, HDL cholesterol, LDL cholesterol, triglycerides, smoking). eGDR variable was retained in the final model of stepwise logistic regression (p < 0.001) and showed the strongest association with proliferative diabetic retinopathy (Wald = 12.73).Conclusions. In type 1 diabetes patients insulin resistance was the most important independent risk factor associated with diabetic proliferative retinopathy.
