FUNCTIONAL AND ANATOMICAL RESULTS DURING VITRECTOMY WITH RETINECTOMY AND RETINOTOMY IN THE TREATMENT OF RHEGMATOGENOUS RETINAL DETACHMENT COMPLICATED BY PROLIFERATIVE VITREORETINOPATHY WITH STAGE C (LITERATURE REVIEW)

Purpose – this literature review contains information from foreign and domestic literature related to the pathogenesis of the development of rhegmatogenous retinal detachment (RRD) and proliferative vitreoretinopathy (PVR), as well as the most modern theories of their occurrence. An important part was the analysis of the subtleties of primary vitrectomy, attention was focused on the features of surgery for RRD complicated by PVR with stage C, namely, the importance of using vital dyes, perfluoro-organic compounds (PFOС), peeling of the inner limiting membrane (ILM) and microgauge surgery. Differences in techniques are discussed, as well as criteria and situations where retinectomy and retinotomy should be performed, and possible complications are mentioned. Clinical examples are analyzed, where patients with first identified RRD, complicated by PVR with stage C, who underwent retinectomy and retinotomy, were studied. Materials and methods The information for this literature review was taken from the PubMed, Elsevier. Results Based on the results of retrospective studies on the use of vitrectomy with retinotomy and retinectomy, a favorable anatomical outcome after primary surgery was achieved in 48.5%-78.2%, and after second surgery in 60%-83.1%. The average postoperative best corrected visual acuity (BCVA) became higher than preoperative. Conclusion Nowadays, there is no universal strategy for the surgical treatment of patients with RRD complicated by PVR stage C. Currently used methods of retinectomy and retinotomy showed high functional results in the postoperative period and reached a favorable anatomical outcome.
