Abstract：
Induction of posterior vitreous detachment (PVD) is one of the most critical steps for the success of retinal detachment (RD) surgery. Failure to completely remove the vitreous can result in re-detachments. We describe a novel technique to induce PVD. After core vitrectomy, perfluorocarbon liquid (PFCL) is injected. The vitreous on the posterior pole is gently stroked, with a diamond-dusted membrane scraper, to create a defect in it. This defect is gradually enlarged to create a ring of rolled out vitreous. The entire vitreous is removed in form of a sheet by lifting the edges of the ring using an internal limiting membrane peeling forceps. PFCL naturally slides into the potential space, gradually extending the vitreous detachment peripherally. With this technique, the vitreous sheet in case of RD can easily, effectively and safely be removed with this technique.
摘要：
玻璃体后脱离（PVD）的诱导是视网膜脱离（RD）手术成功的最关键步骤之一。不能完全去除玻璃体会导致再次脱离。我们描述了一种诱导PVD的新技术。核心玻璃体切除术后,全氟化碳液体(PFCL)注入。轻轻抚摸后极上的玻璃体，用金刚石粉尘的薄膜刮刀，在其中制造缺陷。该缺陷逐渐扩大以形成一圈滚动的玻璃体。通过使用内部限制膜剥离钳提升环的边缘,以片的形式移除整个玻璃体。PFCL自然滑入潜在空间，玻璃体脱离外周逐渐扩展。有了这项技术,玻璃薄片在RD的情况下可以很容易地，有效和安全地删除与此技术。
