Purpose. To determine the effectiveness of the anatomical and functional results of treatment of refractory diabetic macular edema after removal of the inner limiting membrane using the latest generation anti-VEGF drug. Material and methods. We examined 6 patients with 1st type and 2nd type diabetes mellitus. The average age of the subjects was 47.45 ± 27.15 years. Of these, there were 4 women and 2 men. 1st type diabetes mellitus was detected in 2 people, in other patients — 2nd type. 3 patients had previously undergone pan-retinal photocoagulation (from 1st to 2nd stages). All patients received intravitreal injections (anti-VEGF) of Eylea (4–5 injections) during the last year. According to the optical coherence tomogram (OCT), macular edema was recorded, recurring on average after 1.36 ± 0.85 months. All patients underwent surgical treatment. In the presence of lens opacity, surgical treatment was started with phacoemulsification of cataracts. A microinvasive subtotal vitrectomy was performed with the removal of the posterior layers of the vitreous body and proliferative membranes fixed to the retina. The removal of the inner boundary membrane was performed after its staining in the size of two to three diameters of the optic disc without any tamponade. After 2 months, two patients had an increase in retinal thickness in the fovea. These patients received one injection of Vabismo. Results. The compared groups did not differ in morphofunctional characteristics. In the postoperative period, there was a tendency to increase visual acuity and decrease retinal thickness, regression of hard exudates in 4 patients. In 2 patients, an increase in retinal thickness in the fovea was noted after 2 months. After intravitreal injection of the latest generation anti-VEGF drug (Vabismo), these patients also showed an increase in visual acuity, regression of solid exudates and a decrease in retinal thickness. Conclusion. Microinvasive subtotal vitrectomy with removal of the inner limiting membrane in combination with intravitreal injection of the latest generation anti-VEGF drug (Vabismo) is an effective method of treating refractory diabetic macular edema.
