Vitrectomy and scleral buckling methods for proliferative vitreoretinopathy.

The authors operated on 95 eyes with retinal detachment (RD) complicated by proliferative vitreoretinopathy (PVR) using vitrectomy combined with scleral buckling. The retina was successfully reattached in 10 (91%) of 11 eyes with mild PVR (B, C1), 14 (93%) of 15 eyes with moderate PVR (C2-C3), and 52 (75%) of 69 eyes with severe PVR (D1-D3). Thirteen (88%) of 15 eyes in which silicone oil was injected were successfully reattached. Eighty-eight percent of the 76 successfully reattached cases had a postoperative visual acuity of 5/200 or better; the median postoperative visual acuity was 20/200. Severe PVR was the cause of failure in 17 (89%) of 19 eyes in which the retina was not reattached.
