Advances in the surgical instrumentation and vitreoretinal techniques have allowed intraoperative reapproximation of retina to a more normal position. The use of intravitreally injected liquid materials (viscoelastic liquids, liquid perfluorocarbons and silicone oil), as adjunctive agents to vitreo-retinal surgery play an important role in facilitating retinal reattachment. These materials are used as intraoperative instruments to re-establish intraocular volume, assist in separating membranes adherent to the retina, manipulate retinal detachments and mechanically flatten detached retina. Over the longer term, silicone oil maintains intraocular tamponade. One should be cognizant of the potential uses, benefits and risks of each of these vitreous substitutes.
手术器械和玻璃体视网膜技术的进步使得术中能将视网膜重新复位到更接近正常的位置。玻璃体内注射液体材料（粘弹性液体、液态全氟化碳和硅油）作为玻璃体视网膜手术的辅助剂，在促进视网膜复位方面发挥着重要作用。这些材料被用作术中器械，以重建眼内容积，协助分离附着于视网膜的膜，处理视网膜脱离并机械性地展平脱离的视网膜。从长远来看，硅油可维持眼内填塞。人们应该了解每种玻璃体替代物的潜在用途、益处和风险。
