[A comparison of attachment rates between SF6 and silicone oil tamponades following vitrectomy for treatment of complicated retinal detachment].

In this study, 215 eyes with rhegmatogenous retinal detachment and proliferative vitreoretinopathy (PVR) including giant tears, macular holes, perforating injury and traction caused by retinal vascular diseases were treated by vitrectomy and SF6 or silicone oil. The anatomic attachment rates were compared between gas and silicone oil groups in non-vitrectomized eyes and previously vitrectomized eyes, respectively. Both gas and silicone oil groups showed higher attachment rates in stage C of PVR, giant tears with PVR less than stage C2 and macular holes. The gas group showed lower attachment rates in cases with stage D of PVR, giant tear larger than 180 degrees or with PVR C3 or greater than C3, after perforating injury and traction-rhegmatogenous retinal detachment, while silicone oil group showed better attachment rates. The choice of tamponades should be based on different indications.
