title: Long-term results of vitrectomy and perfluorocarbon gas for the treatment of severe proliferative vitreoretinopathy.
abstract: The results of 87 patients who underwent vitrectomy, scleral buckling, and injection of perfluorocarbon gas in one eye each for proliferative vitreoretinopathy of grade C3 (marked, involving three quadrants) or worse were studied. The retinas of 60 of the 87 patients (69%) were attached posterior to the scleral buckle one month after disappearance of the gas, with the initial reattachment rate being inversely proportional to the severity of proliferative vitreoretinopathy. Follow-up data ranging from six to 106 months were available on 54 eyes with attached retinas. Final visual acuity in those patients ranged from light perception to 20/40 and was not related to severity of proliferative vitreoretinopathy or duration of reattachment. Thirty-eight of the 54 patients (70%) had a visual acuity of 20/400 or better. Twenty-nine of the 37 patients (78%) with retinas attached 24 months or longer had the same or better visual acuity than at six months postoperatively. Macular pucker was observed in 16 of the 54 eyes (30%) and was the most frequently seen long-term retinal complication affecting visual acuity.
