To compare 23-gauge stand-alone pars-plana vitrectomy vs vitrectomy with an encircling scleral buckling procedure for the treatment of primary rhegmatogenous retinal detachment.
Prospective, nonrandomized, comparative study.
All 137 eyes of 136 consecutive patients with primary rhegmatogenous retinal detachment (RRD) presented to our service between 2009 and 2012 were offered either stand-alone vitrectomy (PPV group) or vitrectomy with supplementary encircling scleral buckling procedure (PPV plus SB group). All patients underwent gas or silicon oil tamponade. The follow-up was at least 3 months. There were 80 eyes in the PPV group and 57 eyes in the PPV plus SB group. Preoperative and postoperative patient characteristics were recorded in detail. Main outcome measures were single-surgery anatomic success in which we excluded as additional surgery- silicon oil removal with/ without cataract surgery, and final visual acuity with reattachment surgery-related complications.
Single-surgery anatomic success was achieved in 80% and 89.5% in the PPV and PPV plus SB groups, respectively (p=0.137). In phakic eyes, single-surgery anatomic success were 79.1% and 88.9%, and in pseudophakic or aphakic eyes, single-surgery rates were 84.6 % and 91.7%, respectively, in the PPV and PPV plus SB groups (p=0.137). Final reattachment was achieved 91.3% in PPV and 98.2% in PPV plus SB group (р=0.085). In RRD caused by inferior breaks single-surgery anatomic success were 72.7% and 100% in the PPV and PPV plus SB groups, respectively (p=0.005). The final BCVA (p=0.109) was in PPV group 1.25±0.84 logarithm of the minimum angle of resolution [logMAR] and in PPV plus SB group 1.2±0.66 logMAR.
The study shows benefit of vitrectomy with supplementary encircling scleral buckling procedure for the treatment of primary rhegmatogenous retinal detachment with respect to inferior tears and single-surgery anatomic success.
