Determination of the importance of AKR1B1 gene polymorphisms rs759853 and rs9640883 at the diabetic retinopathy became an object of this research. In 39 patients with diabetes mellitus 2 types and diabetic retinopathy it was determined gene polymorphisms by method of polymerase chain reaction in real time. It was shown that both polymorphisms were connected with compensation status of diabetes. Existence of the minor genotype AA of rs759853 promoted the bigger retina central thickness that could point to strengthening of macular edema owing to bigger intracellular sorbitol accumulation. Carriers of the minor allele A rs9640883 (genotypes GA and AA) were operated earlier on the average of six years. This points to bigger progressing of retina pathological process in cases with allele A presence.
