Scleral buckling in phakic uncomplicated primary rhegmatogenous retinal detachment: long-term outcomes

Purpose: Scleral buckling (SB) is a surgical technique that has been used successfully to treat retinal detachments for the last 6 decades. The aim of this study was to report the long-term anatomical and functional outcomes of SB surgery in phakic patients with uncomplicated primary rhegmatogenous retinal detachment (PRRD). This article also outlines the benefits of SB compared to pars plana vitrectomy, such as reducing the risk of developing cataract, high intraocular pressure, and glaucoma, in addition to reducing surgical cost. Methods: We retrospectively reviewed the clinical notes of 90 phakic eyes with PRRD treated with SB surgery that had a minimum of 5 years follow-up. Preoperative and postoperative characteristics were recorded. Main outcome measures were reattachment rate, best-corrected visual acuity (BCVA) improvement, and complications. Results: A total of 90 eyes (88 patients) with phakic PRRD repaired through SB surgery were included. Mean age was 49.2 +/- 14.6 years (range 20-80). Primary and final anatomic success was 96.7% and 100%, respectively. Mean preoperative BCVA was 0.3 +/- 0.31 logMAR (6/12) and mean postoperative BCVA 0.1 +/- 0.2 logMAR (p < 0.001) (6/7.5). There were no cataract or primary open- angle glaucoma cases after 1 year of follow-up. Mean follow-up was 8.5 +/- 2.6 years (range 5-13). Conclusions: We report a high single operation success rate over time in phakic PRRD, repaired through SB surgery. Functional and anatomical success was maintained throughout the follow-up without complications. Therefore, the authors recommend the use of this technique in selected cases in order to reduce morbidity and the incidence of reoperations.
