Pneumatic retinopexy versus scleral buckling for the management of primary rhegmatogenous retinal detachment

Abstract

Background and objective To compare pneumatic retinopexy (PnR) and scleral buckling (SB) for repair of primary rhegmatogenous retinal detachment. Materials and Methods Single-centre retrospective analysis of patients undergoing PnR and SB. Inclusion criteria comprehend phakic patients with a single retinal break or a group of breaks in detached retina in the same quadrant above the 8- and 4-o’clock meridians. A total of 184 patients were included, respectively 106 underwent PnR and 78 SB. Follow-up time was 6 months. Results Final visual outcome did not differ significantly between the two procedures (P  =  0.12). Single-procedure reattachment rate was significantly higher in SB (94%) than in PnR (68%) (P < 0001). Anatomical success rate was not influenced by macular involving. Reattachment rate in repeated PnR was 95% and in these patients visual outcome did not statistically differ compared to those reattached with first attempt (P  =  0.196). Total reattachment rate including repeated procedures was 87% in PnR group and 94% in SB group, the difference was not significant (P  =  0.06). Conclusion SB has a higher single reattachment rate than PnR. However, final visual outcomes of both procedures are comparable. In selected cases, PnR can be repeated with a high successful rate.
