To date, the problem of rhegmatogenous retinal detachment (RD) relapses due to the proliferative vitreoretinopathy (PVR) progression remains unsolved, there is no single surgical treatment algorithm for retinal detachment, and even more so for its recurrence. The aim is to evaluate the structure of surgical care provided to patients with RD using extensive clinical material, taking into account different methods used, frequency of RD recurrences, frequency of reoperations. Materials and methods. The study was carried out in the vitreoretinal department of the Ophthalmological Center of the City Multifunctional Hospital No. 2 of St. Petersburg. 1502 cases of hospitalization for rhegmatogenous retinal detachment during 2015-2016 have been analyzed, results of surgical treatment have been assessed, number of relapses and frequency of reoperations have been established. Results. RD recurrence after surgical treatment occurs in 20.6% of patients, and vitrectomy is applied twice as often as extrascleral procedures. The use of endovitreal techniques is generally more effective than of extrascleral ones.
