Silicone Oil vs Gas Tamponade in Retinal Detachment Treatment

Retinal detachment complicated by PVR can be challenging to treat. While some cases respond well to pars plana vitrectomy and temporary support from intraocular gas, others may redetach. Preliminary findings suggest that prolonged support with liquid silicone can improve success rates, but there may be complications such as glaucoma and keratopathy. This study aims to compare the benefits of silicone oil versus gas as support methods in this procedure. It focuses on two groups: those who haven't had a prior vitrectomy (Group 1) and those who have (Group 2). The goal is to find a more effective and safer treatment approach for this condition. During the study, all participants undergo vitrectomy and are randomly assigned to receive either silicone oil or gas. The surgical procedure is standardized to relieve retinal traction, and the eye's response is assessed using an intraocular air support. The assignment to silicone oil or gas only happens after the surgical procedure to avoid any bias. Participants are then examined multiple times over a 36-month period, with repeat surgery allowed if necessary. The study's end points are visual acuity of 5/200 or greater and macular reattachment for 6 months following the final surgery. The success rates and complication rates of the two support methods are then compared.
