Chandelier-assisted segmental scleral buckling for rhegmatogenous retinal detachment repair

Abstract

Aim: To evaluate a modified technique for scleral buckling surgery using chandelier endoillumination and minimal segmental buckling through a small conjunctival incision in rhegmatogenous retinal detachment repair. Methods:A prospective interventional case study included 30 phakic eyes with primary rhegmatogenous retinal detachment (RRD) that was repaired by chandelier assisted scleral buckling (SB) using wide angle viewing (WAV) noncontact lens. A surgical procedure was performed to repair a break using transconjunctival sutures and a radial sponge was placed through a regional conjunctival opening. Anatomical and visual outcome at 6 months were the major outcome measures. Minor outcome measures included other postoperative complications. Results:The mean ± standard deviation BCVA was improved from 0.33±0.61 preoperatively to 0.13±0.36 logMAR units 6 months postoperatively. External subretinal fluid drainage was performed in 18 cases (60%). Air injection was required in all patients (100%). Paracentesis was performed in 11 cases (37%). The primary anatomical success of retinal reattachment was achieved in all cases. Three patients (10%) experienced epi-retinal membrane (ERM) formation after 3 months. No other surgical complications were detected during follow up period. Conclusion:In conclusion, scleral buckling using a cannula-based chandelier endo-illuminator is a modified new technique and is promising for the management of rhegmatogenous retinal detachment.
