title: [The prevalence of diabetic retinopathy in subjects with type 2 diabetes of one year and less duration].
abstract: Cases of diabetic retinopathy (DR) at the preclinical stage of diabetes mellitus type 2 (DMT2) can't be explained considering the conventional theory on etio-pathogenesis of diabetic microangiopathy. The present research aimed to study the prevalence of DR among the patients with the newly diagnosed DMT2 and to analyze the possible causes of formation of this complication in the period preceding the period of hyperglycemia. According to the data of the present study the DR prevalence in the patients with newly diagnosed DMT2 equals to 16,4%. The chance of the existence of DR among the patients over 45 is 2,6 times higher than among those of 45 and younger. Proceeding from the results of the present study the assumption is made on the presence of pathogenic mechanisms conditioning initiation of diabetic microvascular pathology before stabilization of hyperglycemia at the stage of the impaired glucose tolerance.
