DYNAMICS OF MORPHOFUNCTIONAL PARAMETERS OF RESISTANT DIABETIC MACULAR EDEMA AFTER SURGICAL TREATMENT

Anti-angiogenic injections are currently established as the «gold standard» for treating diabetic macular edema (DME). Vitreoretinal surgery is indicated in cases involving an epiretinal membrane or vitreoretinal traction syndrome. Some physicians consider it feasible to perform vitrectomy with the removal of the internal limiting membrane in patients with this condition. The objective of this study is to assess changes in the morphofunctional parameters of the retina in patients with resistant forms of DME who have undergone surgical intervention. At the N.I. Pirogov National Medical and Surgical Center, 75 patients diagnosed with DME unresponsive to conservative therapy (anti-vascular proliferation therapy, retinal laser coagulation) were operated on. All patients were divided into three groups based on the type of intervention. Evaluation of best-corrected visual acuity after surgery revealed a statistically significant improvement in this parameter among patients in the second and third groups compared to those in the first group six months post-operation. Patients in the third group showed a notable reduction in retinal thickness in the foveal area one month after the intervention. A significant decrease in edema was observed in patients from the second and third groups compared to those in the first group over the period from one month to one year. When assessing light sensitivity, a significant improvement in parameters was noted in patients from the second and third groups compared to the data from the first group one week after the surgery. The results confirm the high effectiveness of vitreoretinal surgical intervention in patients with resistant diabetic macular edema, affirming the possibility of selecting a surgical approach.
