[Results of vitreous surgery for proliferative vitreoretinopathy].
During the past four years, we performed vitreous surgery on 73 eyes with rhegmatogenous retinal detachments complicated with severe proliferative vitreoretinopathy (PVR). We analyzed the surgical outcome of PVR according to the revised classification of PVR Grade C (1991). After a mean follow-up period of 19 months, the retinas were successfully reattached in 62 of 73 eyes (85%). The reattachment rate in the eyes with only posterior proliferation was high (96%), regardless of the extent of posterior proliferation. However, the reattachment rate in the eyes associated with anterior proliferation was markedly low (57%), depending on the extent of anterior proliferation. Among 62 eyes with successfully reattached retinas, 39 eyes (63%) had an improved postoperative visual acuity. These results demonstrated that the eyes with anterior PVR have a worse reattachment rate than the eyes with only posterior PVR. Using the revised classification of PVR, we were able to analyze the surgical outcome of PVR which could not be classified by the old classification.
