Outcome of pars plana vitrectomy with silicon oil versus scleral buckling in primary retinal reattachment surgery

Objective: To evaluate the outcome of primary pars plana vitrectomy with silicon oil tamponade versus scleral buckling procedureas a treatment for rhegmatogenous retinal detachment. Methodology: This prospective, comparative, interventional study was conducted from July 2008 to June 2009. Patients were selected and divided into two groups. Pars plana vitrectomy (group I) or scleral buckling (group II) was performed as primary procedure. Patients were followed for 06 months after surgery. Results: Anatomical outcome in pars plana vitrectomy procedure was 96.2% as compared to scleral buckling procedure 87.0%. Functional outcome in pars planavitrectomy, best corrected visual acuity of 6/6 – 6/18 was attained in 34.6%, in sclera buckling procedure 65.2% at 06 months. Conclusion: Anatomical outcome in pars plana vitrectomy is better as compared to scleral buckling. Visual outcome and visual rehabilitation is earlier and better in scleral buckling as compared to pars plana vitrectomy.
