Summary. The purpose of research – a comparison of the distribution of genotypes and alleles of SNPs rs759853 and rs9640883 AKR1B1 gene in patients with diabetic retinopathy (DR), cataract, and type 2 diabetes mellitus (DM2T). 409 people were included in investigation, which were divided into fi ve groups: 1 – 98 cataract patients who had not DM2T; 2 – 76 patients with cataract and stage I DR (no visible changes in the fundus); 3 – 64 patients with cataract and non-proliferative DR; 4 – 64 patients with cataract and proliferative DR; 5 – the control group (107 patients) without ophthalmic pathology relevant to other groups by age and sex. The results of study showed that according to polymorphism rs759853 AKR1B1 gene it was determined the reduction of the frequency of the ancestral genotype G/G, with increased frequency of heterozygous G/A in groups of patients with cataract and DM2T without retinopathy, and increase of the frequency of the mutant homozygotes A/A for DR (3,3–3,9 times). In general, in case of DR it was marked decrease of the frequency of the ancestral allele G and increasing of the frequency of the mutant allele A polymorphism rs759853 AKR1B1 gene. By polymorphism rs9640883 gene AKR1B1 it was showed signifi - cant increase of the frequency of the ancestral genotype G/G in patients SD2T (1.4–1.6 times) due to reduction of the frequency of heterozygous G/A (in 1.4–1.9 times). Since homozygous genotype A/A in general turned out to patients with DR, it was possible to justify the assumption of the role of projective rs9640883 A allele in the DR development.
