Summary:
The purpose of the study is to assess the effect of vitreoretinal interface changes in patients with diabetic macular edema as far as the effectiveness of anti-VEGF therapy is concerned. Material and Methods. The study included 198 patients (198 eyes) with diabetic macular edema (DME). Two groups were formed: group 1 — patients without pathological changes in vitreoretinal interface (VRI); group 2 — patients with pathological changes in VRI. We studied the best-corrected visual acuity according to the Snellen table, central retinal thickness and VRI condition according to optical coherence tomography before the intravitreal administration and 1 month after. Results. Significant differences in best-corrected visual acuity were observed before and 1 month after intravitreal administration in both groups (p<0.05). A significant decrease in central retinal thickness in both groups was revealed (p<0.001). A statistically significantly larger average decrease in the thickness of the central retinal in group 1 was obtained (p<0.001). Conclusion. Improvement in visual acuity is significant in anti-VEGF therapy of DME with normal VRI, while with the pathological VRI it is not significant. The degree of improvement in average visual acuity and the degree of decrease in the average thickness of the central retina during anti-VEGF therapy of DME is significantly lower in the presence of VRI pathology. Presence of the vitreoretinal interface pathology reduces the effectiveness of antiangiogenic therapy of DME.
