Diabetic retinopathy (DR), is the cause of population invalidization which is diagnosed in 30–90% of patients.

Purpose - to examine vitamin D levels in patients with diabetic retinopathy.

Materials and methods: Under our supervision, there were 48 patients (93 eyes). Among examined 26 patients had nonproliferative form DR and 19 – proliferative DR.

Results: Among the patients with type 1 diabetes 23 (52%) patients had a marked deficiency of vitamin D3. And in 48% was determined by hypovitaminosis. In type 2 diabetes in 25 (59%) patients experienced a deficiency of vitamin D3, and in 41% – hypovitaminosis. In patients defined different levels of vitamin D3, depending on the severity of diabetic retinopathy. Thus the presence of proliferative diabetic retinopathy observed moderate degree of vitamin D3 deficiency (37.5±6.1). For patients with nonproliferative DR are characterized by the presence of hypovitaminosis 25(OH)D (63.9±6.6).

Conclusion: For patients with the DR in type 1 diabetes observed average severity of vitamin D3 deficiency, and in type 2 diabetes – severe.
