Comparison of Chandelier-Assisted versus Standard Scleral Buckling for the Treatment of Primary Rhegmatogenous Retinal Detachment: A Systematic Review and Meta-Analysis.

INTRODUCTION

Compare the anatomical and functional outcomes, operation duration, and complication rates between standard scleral buckling (SSB) and chandelier-assisted scleral buckling (CSB) for phakic eyes with rhegmatogenous retinal detachment (RRD).

METHODS

PubMed, Embase, and Cochrane Library databases were searched from inception to June 2024. The primary endpoint will be set as a final success. The secondary endpoint will be primary success, operation time, and final BCVA.

RESULTS

Our meta-analysis showed that there is no statistical difference between CSB and SSB for the final success rate (RR = 1.00, 95% CI = 0.97-1.03). For the primary success rate, there is no statistical difference between CSB and SSB (RR = 1.00, 95% CI = 0.94-1.06). For operation time, our meta-analysis showed that the CSB group is less than the SSB group (pooled MD = -15.8, 95% CI = -22.60 to -9.00). For postoperative complications, our study shows that the CSB group presented with lower pooled risk than the SSB group (RR = 0.59, 95% CI = 0.41-0.89). There is a trend that the ERM formation risk is higher in the CSB group if there is no routine suture for the sclerotomy (p = 0.08).

CONCLUSION

CSB showcases a significantly reduced operation duration and less postoperative complication in contrast to the SSB group, maintaining comparable primary and ultimate anatomical success rates as well as final BCVA.
