Surgical Outcome of Scleral Buckling Compared With Scleral Buckling With Vitrectomy for Treatment of Macula-off Retinal Detachment

BACKGROUND AND OBJECTIVE: To compare the surgical outcome of scleral buckling (group 1) versus scleral buckling with pars plana vitrectomy (group 2) for the repair of macula-off rhegmatogenous retinal detachment without proliferative vitreoretinopathy. PATIENTS AND METHODS: A retrospective chart review was performed. RESULTS: Eighty-three patients were identified in group I and 63 patients in group 2. Presenting visual acuity was 4/200 in group 1 and 3/200 in group 2. Median duration of detachment prior to surgery was 5 days in group I and 6 days in group 2. There was no statistical difference in best-corrected (P = .59) or most recent (P = .75) visual acuity between groups. Median best-corrected visual acuity was 20/30 and median most recent visual acuity was 20/40 in both groups. Significantly more additional procedures were performed in group I than in group 2 (21.7% vs 7.9%, respectively; P = .024). The final reattachment rate was 96.4% in group I and 98.4% in group 2. Proliferative vitreoretinopathy developed in 15.7% of patients in group I and 4.8% in group 2 (P = .037). CONCLUSION: Visual outcome of scleral buckling is similar to scleral buckling with pars Plana vitrectomy for the treatment of macula-off rhegmatogenous retinal detachment in patients without proliferative vitreoretinopathy. Patients undergoing scleral buckling only are at an increased risk of developing proliferative vitreoretinopathy and requiring additional procedures.
