Comparison of scleral buckling with combined scleral buckling and pars plana vitrectomy in the management of rhegmatogenous retinal detachment with unseen retinal breaks
Abstract:Conventional scleral buckling was found to be a safe and effective technique in the primary management of uncomplicated, rhegmatogenous retinal detachments with unseen retinal breaks when the media is clear.
“…Numerous studies have been published recommending one of the two methods [1,4,13,14,20,24,26,27,29,30,32]. We could identify no consensus among several editorial comments on this issue [6, 15-18, 33, 34].…”
In the recruitment lists of the SPR Study of the year 2000, RRD of medium severity was present in nearly one third of the patients with primary RRD. These findings emphasise the clinical relevance of the SPR Study.

“…However, combining scleral buckle surgery with PPV may increase the risk of intraoperative and postoperative complications (especially choroidal haemorrhage) which occur more frequently in combined surgery [20,23].…”
“…They found an 83% primary success rate in the PPPV group and 93% in the SBS group. Tewari et al compared SBS and PPPV in patients with undetected retinal breaks in a prospective, randomised fashion [40]. The authors found a higher reattachment rate following PPPV, but a better postoperative visual acuity following SBS; neither of the differences reached statistical significance.…”
Primary pars plana vitrectomy is still flawed by a relatively high primary redetachment rate following the initial procedure. The advantages of the technique are a high final reattachment rate and relatively good functional results in a subset of patients with more complicated types of RRD. The risk factors for postoperative failures following PPPV for RRD match to a large extent those following scleral buckling surgery (SBS). Future improvements of the technique will have to focus on modifiable risk factors, such as details of the surgical procedures, surgical training and case selection, to distinguish it from SBS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
