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.
