Today diabetes mellitus (DM) is one of the leading medical and social problems. Its complications lead to terrible concomitant pathologies that qualitatively affect the lives of patients. At the end of 2019, there were more than 463 million people with diabetes in the world and this number is increasing every year. Diabetic retinopathy (DR) is one of the most severe complications of DM on the organ of vision. Secondary neovascular glaucoma (NG) is a manifestation of the end-stage proliferative DR. This is a relatively rare but difficult-to-treat pathology that often leads working-age patients to disability and impaired social adaptation. The main objective of treatment for NG is to compensate for intraocular pressure (IOP), but conservative (drug) therapy is often ineffective. Therefore, doctors are forced to use surgical methods of treatment. At the same time, do not forget about the multiple complications during the operation, as well as in the early and late postoperative periods. A special feature of the course of NG in patients with DM is its combination with the failure of the ligamentous-capsular apparatus of the lens, iris bombage, anterior and posterior synechiae, traction retinal detachment and various hemorrhagic complications. All this allows us to talk about the so-called diabetic glaucoma (DG). Currently, drainage devices have become the standard in the treatment of refractory NG. The effectiveness of such operations according to various sources is about 70-80% of success. Purpose. To assess the condition of patients with DM in the late (10-15 years) postoperative period after performing NG drainage surgery, to analyze the effectiveness of the intervention by studying the dynamics of IOP, the presence or absence of pain syndrome and various intraocular complications. Material and methods. During the period 2006-2020, 150 patients with NG and DM were operated on in the Department of Diabetic Retinopathy of the Federal State Budgetary Institution «Endocrinology Research Centre» of the Ministry of Health of the Russian Federation. Results. In 100% of the postoperative period, the pain syndrome was stopped. And also, in 59.7% of cases, the presence of late complications: vascular thorn, EED, subatrophy and anophthalmos. Conclusion. Despite the presence of complications, drainage surgery in patients with DM continues to be an effective method of choosing surgical treatment for patients with uncompensated NG.
