The study aims to review the efficacy of scleral buckling and vitrectomy in the management of cases of advanced PVR (grades C and D) according to the Retina Society Classification System). Sixty cases of total retinal detachment complicated by the more advanced grades (grades C and D) of PVR were treated with sclera' buckling alone (24 eyes) and vitrectomy and internal tamponade (36 eyes). The overall success rate of the scleral bucking-treated eyes was 57.6%, and in the vitrectomytreated eyes was 70.5%. Of the anatomically successful cases, 89.7% achieved a final visual acuity of counting fingers or better. The major causes of surgical failure were redetachment from persistent vitreoretinal traction (15.5%) and intraoperative complications (11.6%). Conclusion: Scleral buckling alone should be considered as the primary surgical procedure in selected cases of PVR characteristically, grade-C. In more advanced cases vitrectomy combined with internal tamponade might offer a better result.
