Purpose: To report a case of early postoperative scleral buckle slippage because of the dehiscence of scleral belt loop tunnels.
Method: Case report.
Results: A 54-year-old woman presented with painful diplopia after a combination pars plana vitrectomy and scleral buckling procedure. Ocular movements were limited. Forced duction testing was restricted in all directions. Anterior slippage of the silicone band was suggested on computed tomography (CT) scans and was confirmed with surgical exploration. During surgery, it was found that thin-roofed scleral belt loop tunnels were dehisced in three quadrants leading to anterior slippage of the buckle. The displaced buckle was removed. Diplopia and pain resolved, and ocular motility improved immediately afterward. The retina remained attached at six months follow-up. A supplemental video summarizes the surgical findings and postoperative results.
Conclusion: Spontaneous dehiscence of scleral belt loops may occur in thinly dissected scleral tunnels. Painful eye movement, diplopia, and a positive forced duction test should raise suspicion about a displaced scleral buckle. A CT scan may help with the diagnosis. Early diagnosis and immediate surgical intervention are needed to minimize patient discomfort and to improve long-term ocular motility.

Department of Trauma and Orthopaedics, Barts Health NHS Trust, London, GBR.
A significant percentage of patients with retinopathy of prematurity (ROP) who progressed to stages 4 and 5 of ROP will require surgical intervention. Scleral buckling surgery is widely employed for the restoration of retinal detachment in advanced cases of ROP. This systematic review and meta-analysis aim to review the anatomical and visual outcomes following scleral buckling surgery in ROP of stages 4 and 5.

Department of Ophthalmology, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, Tainan, Taiwan.
Objectives: To evaluate the differences in surgical outcomes between scleral buckling (SB) with noncryopexy and cryopexy methods.
Methods: We systematically searched the Embase, Medline, Cochrane Library, and Scopus databases for randomized controlled trials (RCTs) published from their inception until January 1, 2024. A random-effects model was applied, and outcomes are presented as risk ratios (RRs) or standardized mean differences with 95% confidence intervals (CIs).

Wills Eye Hospital Mid Atlantic Retina, Thomas Jefferson University, Philadelphia, PA, USA.
Introduction And Primary Objective: Pediatric rhegmatogenous retinal detachment (RRD) presents unique challenges in diagnosis and management. A thorough evaluation of family, medical, and ocular history is helpful, as systemic and genetic conditions can predispose children to RRD. Trauma, high myopia, and history of prematurity are also common risk factors.
