Comparison of four surgical techniques for management of pseudophakic and aphakic retinal detachment: a multicenter clinical trial

Purpose To compare the visual and anatomical outcomes of four surgical techniques to manage pseudophakic and aphakic retinal detachment (PARD). Methods In a multicenter randomized clinical trial, 211 eyes of 211 patients with PARD and proliferative vitreoretinopathy (PVR) grade B or less were randomly assigned to one of the four treatment groups: (1) scleral buckling (SB), 50 eyes, (2) vitrectomy without band, 51 eyes, (3) vitrectomy with encircling band (EB), 58 eyes, and (4) triamcinolone acetonide (TA) assisted vitrectomy, 52 eyes. Patients were followed for 12 months after the surgery. The best-corrected visual acuity (BCVA) and retinal reattachment rate at each follow-up time point were considered as the primary outcome measures. PVR, macular pucker, and cystoid macular edema were considered as the secondary outcomes. Results Visual improvement was achieved in all treatment groups relative to the baseline at all time points (all P s 0.99). There were no statistically significant differences among the groups in terms of adverse events. Conclusions SB, TA-assisted vitrectomy, and vitrectomy with and without buckle had comparable outcomes in the management of PARD.
