PURPOSE：To search for the treatment of recurrent detachment of retina with severe proliferative vitreretinopathy(PVR) by vitreoretinal surgery. METHODS:Fourty-seven cases of recurrent detachment of retina with severe PVR treated by vitrectomy between September 1987 and Noverber 1994 were systematically reviewed. RESULTS:On discharge from the hospital,the retina was totally reattached in 30(63.8%)of the 47 cases,partially reattached in 9 cases (19.1%)and still detached in 8 cases(17.1%). CONCLUSIONS:In addition to using the surgical procedures similar to the conventional vitreoretinal surgery,the histopathological change induced by the previous operation in sick eyes should be paid attention to. （Chin J Ocul Fundus Dis,1996,12: 10-12）
