The necessity and role of scleral buckling for rhegmatogenous retinal detachment

Purpose of reviewWith a decline in the use of scleral buckling for rhegmatogenous retinal detachment (RRD) repair in recent years, this review seeks to provide a summary of the most recent research findings regarding the role of scleral buckling in the repair of RRD.Recent findingsMany recent studies have compared visual and anatomic outcomes between scleral buckling and pars plana vitrectomy (PPV) for RRD repair. Some suggest superior outcomes with primary scleral buckling, particularly in younger, phakic patients, and in association with other risk factors that we review. Children do best with primary scleral buckling surgery. Functionally, scleral buckling may also result in lower rates of retinal displacement compared to PPV. When PPV is necessary, a supplemental buckle may benefit certain patients, while the advantage remains unclear in other clinical scenarios and necessitates further investigation.SummaryScleral buckling is an important technique for the repair of RRD and it is crucial to continue training retina surgeons in this technique to maximize patient outcomes.
