During the so called ILM peeling, the surgeon removes a layered structure that includes the basal membrane of MC, cells and fibers attached to its vitreal side, and one more layer comprised by PCS and rather readily torn off from the main massif. The functional significance of this previously unknown structure as well as the effect of its partial removal during surgical manipulations with neurosensory retina in the macular region is yet to be investigated.

The paper presents the results of developing a new technology for recording the images of posterior fundus tissues, which allows us to improve the visibility of information-significant objects reducing the light load on the retinal tissue. Considerable attention is paid to the issue of increasing the robustness of the recorded image in low light conditions.

Diabetes mellitus and diabetic retinal lesions are a global challenge for healthcare systems and one of the leading causes of severe vision loss among the working age population. Retinal laser coagulation remained the standard of therapy and the only possible treatment for diabetic macular edema (DME) in the 80-90s of the last century. The introduction of anti-VEGF therapy and glucocorticoids into the wide practice has significantly expanded the range of possibilities of DME treatment, allowing not only to stabilize patients vision, but also to improve it. The analyses of the large randomized clinical trials results are made and presented in this article, that highlight the basic principles of the contemporary DME treatment. This information is intended to help the ophthalmologist to develop the most optimal approach to treatment, considering the individual characteristics of each patient and the evidence-based efficacy and safety data of different methods.
