[Vitreous surgery for retinal detachment with severe proliferative vitreoretinopathy and probe of failed cause]

Eighty-one cases (81 eyes) of retinal detachment with severe proliferative vitreoretinopathy were treated using vitrectomy, scleral buckling and air or silicone oil tamponade technique. After a follow-up period of 6-28 months, 54 cases obtained anatomic retinal attachment (66.7%). For the serious cases of PVR D3, we also gained a success rate of 50%. Vision improved in 50 cases, whereas 34 cases got a vision better than 0.05. For the failed cases, cause that prevent the retina from attachment was probed. We think that vitrectomy is an essential and important procedure for retinal detachment with severe PVR, membrane peeling is the key of success and prevention of reproliferation can avoid recurrent retinal detachment and further raise the success rate of treatment. A new classification is recommended in this article.
