Abstract
BACKGROUND/ OBJECTIVES: The aim of this study was to compare surgical outcomes and postoperative characteristics, between eyes that underwent pars plana vitrectomy (PPV) for RRD, with air or different gas agents as tamponade. SUBJECTS/ METHODS: The records of 262 patients that underwent PPV for RRD with air or different gas tamponades and a follow-up of at least 6 months were examined. Only cases with superior retinal breaks were included. Demographic, pre-, intra- and postoperative characteristics including rate of recurrence and complications were analysed. RESULTS: 48 patients were treated with air and 214 were treated with gas. No differences were found in success rate between air and gas group at both 3 and 6 months (respectively, 93.8% vs 93.6 and 100% vs 100%, all P values > 0.05). Postoperative best-corrected visual acuity (BCVA) was significantly higher in the air group compared with the gas group 7 days and 1 month postoperatively (respectively, 0.2 ± 0.4 vs 2.6 ± 0.5, P < 0.001 and 0.1 ± 0.4 vs 0.4±0.9, P = 0.04). The occurrence ocular hypertension at 1 month postoperatively was significantly higher in the gas group compared with the air group (15.4 % vs 0%, P < 0.001). At 6 months, the prevalence of epiretinal membrane (ERM) was significantly higher in the gas group compared with air group (4.2% vs 16.8%, P = 0.02). CONCLUSIONS: Air was comparable to gas tamponades in terms of surgical outcome and BCVA at 6 months. In addition, air allowed an earlier visual recovery and resulted in a lower rate of postoperative ocular hypertension and ERM.
