Aim. To investigate the technical difficulties of performing the stages of vitreoretinal surgery, the peculiarities of the surgical technique in young patients with the proliferative stage of diabetic retinopathy (DR). Methods. Twelve patients (12 eyes) with type 1 diabetes mellitus (DM) were selected. Their average age was 26±2 years (from 19 to 30 years). There were 4 men and 8 women. All patients had DM since childhood. Selection criteria: presence of indications for vitreoretinal surgery for proliferative DR, age of patients with type 1 DM not more than 30 years, onset of DM in childhood. Results. Initially, the clinical manifestations of proliferative DR in young people with type 1 DM were distinguished by the severity of neovascular and fibrous growths, a tendency to hemorrhages, and the complexity of preoperative preparation in the form of panretinal laser coagulation, at least partial. Surgical removal of vitreoretinal adhesions and elimination of neovascularization zones differed in technical difficulties associated with their higher density and the area of retinal tissue lesion. Conclusion. Surgical treatment of proliferative DR in young patients has a number of technical difficulties associated with the density and length of fibrovascular vitreoretinal growths, the difficulty of separating them due to the high tendency of newly formed vessels to hemorrhages. Key words: proliferative diabetic retinopathy; endovitreal surgery; type 1 diabetes mellitus; young age.
