AIM: To evaluate the safety and efficacy of a minimally restricted face-down postoperative positioning following pars plana vitrectomy (PPV) with gas tamponade for primary rhegmatogenous retinal detachment (RRD). METHODS: Patients with primary RRD treated with PPV and gas tamponade and followed up for at least 6mo were selected for the study. All phakic eyes underwent simultaneous cataract surgery. The patients were required to be in a postoperative position that prevented downward flow of retinal tears. Patients with macular detachment were positioned face-down for only a couple of hours. The patients were assessed for preoperative and postoperative best-corrected visual acuity (BCVA), anatomical retinal reattachment rate, and postoperative complications. RESULTS: In total, 40 eyes of 39 patients with primary RRD were included in the study. A single tear was present in 30 eyes (75.0%), multiple retinal tears were present in nine eyes (22.5%), and oral dialysis was present in one eye (2.5%). The anatomical success rate was 90.0% (36 cases) after the primary surgery, and the final anatomical success rate was 100%. The BCVA improved significantly (P<0.001) from 0.75 logarithm angle of resolution (logMAR) preoperatively to 0.12 logMAR at the final visit. Postoperative complications included intraocular pressure elevation (≥25 mm Hg) in 11 patients (27.5%), fibrin formation in two patients (5.0%), pupillary capture of the intraocular lens in two patients (5.0%), and posterior synechia in one patient (2.5%). CONCLUSION: A minimally restricted face-down and flexible postoperative positioning after PPV and gas tamponade for primary RRD is effective and safe. International Journal of Ophthalmology Press.
