[Episcleral circular buckling in surgical treatment of recurrent rhegmatogenous retinal detachment after vitrectomy].

Unlabelled: Despite the improvement of the surgical technique of vitreoretinal interventions, the number of recurrences of rhegmatogenous retinal detachment (RRD) remains quite high.

Purpose: Evaluation of the effectiveness of episcleral circular buckling (ECB) in the treatment of recurrent RRD after vitrectomy due to progression of proliferative vitreoretinopathy (PVR).

Material And Methods: The study analyzed the results of surgical treatment of 21 patients (21 eyes) with recurrent RRD after primary vitrectomy. All patients underwent standard preoperative examination including visometry, tonometry, ophthalmobiomicroscopy, and additionally, optical coherence tomography was performed to assess the involvement of the macular area; the presence of anterior proliferative vitreoretinopathy was determined by ultrasound biomicroscopy, axial eye length was measured with an optical biometer. All patients underwent ECB, in some cases combined with repeated vitreoretinal surgery.

Results: Preliminary results of the study showed high efficiency of ECB exclusively, as well as ECB combined with revision of the vitreal cavity in case of RRD recurrence after primary vitreoretinal surgery, which amounted to 95% after one additional operation and removal of silicone oil.

Conclusions: Episcleral circular buckling in the treatment of recurrent RRD after vitreoretinal surgery is a multifunctional and safe method that allows achieving favorable functional and anatomical outcomes.
