CHANDELIER-ASSISTED VERSUS STANDARD SCLERAL BUCKLING FOR PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT: A Randomized Clinical Study.

Abstract

To compare anatomical outcomes, functional outcomes, and rate of complications of standard scleral buckling (SSB) versus chandelier-assisted scleral buckling (CSB) in phakic eyes with rhegmatogenous retinal detachment. Patients were randomly assigned to either SSB or CSB. Surgical success/failure rate, corrected distance visual acuity, surgical operating time, and rate of intraoperative and postoperative complications including epiretinal membranes by spectral domain optical coherence tomography were compared between groups. A total of 50 eyes of 49 patients were included. At 6 months, there was no statistically significant difference between groups in primary success, or final anatomical success ( P > 0.9); mean corrected distance visual acuity at any visit ( P values >0.05); or mean surgical time: 120.3 ± 39.05 and 102.48 ± 43.76 minutes for the SSB and CSB, respectively ( P = 0.1). The CSB had a higher rate of postoperative complications (34.8%) compared with the SSB (3.8%) ( P < 0.05). On spectral domain optical coherence tomography, CSB had a statistically significant higher rate of epiretinal membranes compared with SSB (44% vs. 19% [ P < 0.05]) and showed vitreous entrapment in the chandelier sclerotomy site on the ultrasonic biomicroscopy. Chandelier-assisted scleral buckling surgery does not offer encouraging advantages over SSB. On the contrary, we detected a higher rate of complications with CSB especially epiretinal membranes development.
