Surgical outcome of scleral buckling versus pars plana vitrectomy in primary pseudophakic rhegmatogenous retinal detachment.

Abstract

Objective: To evaluate anatomical and visual outcome of scleral buckling surgery versus pars plana vitrectomy in pseudophakic patients with rhegmatogenous retinal detachment. Materials and Methods: Sixty patients having rhegmatogenous retinal detachment were divided randomly in two groups of thirty patients each. In group (A) 30 patients underwent conventional scleral buckling and in group (B), 30 patients with retinal detachment had pars plana vitrectomy. All the per-operative and postoperative complications were recorded. The outcome measures of study were visual outcome and anatomical status of retina, after retinal re-attachment surgery. The patients were followed at least six months after surgery regarding, visual acuity, intra-ocular pressure, retinal re-attachment. Results: Anatomical success rate in Scleral buckling group was 86.66 % and 13.33 % patients had re-detachment, so pars plana vitrectomy was performed. One patient was managed with intra-vitreal SF6 gas injection and 360 degree laser barrage. Anatomical success rate in pars plana vitrectomy group was 90 %, while 10 % patients were managed by second surgery. No significant complication was noted in both types of surgeries. Conclusion: Pseudophakic rhegmatogenous retinal detachments can be managed effectively by pars plana vitrectomy and scleral buckling, with comparable visual and anatomical outcome. Key words: Scleral buckle, Pars plana vitrectomy, Pseudophakic, Rhegmatogenous retinal detachment.
