Anatomical outcome following pars plana vitrectomy alone versus pars plana vitrectomy with scleral buckling for the repair of rhegmatogenous retinal detachment.

AIM: To compare the anatomical outcome in terms of retinal reattachments following pars plana vitrectomy (PPV) versus combined pars plana vitrectomy and scleral buckling(PPV/SB) for the repair of primary rhegmatogenous RD. MATERIALS AND METHODS: 160 patients were included in the study. It was conducted at Institute of Ophthalmology, Unit-3, Mayo Hospital, Lahore. It was a quasi‑experimental study. The patients with Rhegmatogenous Retinal detachment were divided into two groups (80 each). The reattachment surgery was done, and whereas group A patients underwent Pars Plana Vitrectomy, group B patients were treated with Pars Plana Vitrectomy and Scleral Buckling. Ethical approval was taken from the institutional review board (IRB) of KEMU Lahore. RESULTS: Out of 160 (80 in each group) cases, on the comparison of anatomical outcome in both groups, it was found that 67.5% (n=54) in Group-A and 48.75%(n=39) in Group-B had successful retinal re-attachment after the respective surgeries. The difference was significant (p = 0.01). CONCLUSION: We concluded that on the comparison between pars plana vitrectomy (PPV) versus combined pars plana vitrectomy and scleral buckling(PPV/SB) for the repair of primary rhegmatogenous RD, the anatomical outcome in terms of retinal reattachments was better in PPV group and the addition of scleral buckling had no advantage on PPV.
