Abstract
En 中文
Background: Intravitreal tamponades are essential tools in vitreoretinal surgery, widely used for the treatment of posterior segment pathologies. Conventional tamponade agents - such as intraocular gases and silicone oils - have significantly improved surgical outcomes but are associated with limitations including the need for specific postoperative positioning, intraocular pressure fluctuations, and in some cases, secondary removal procedures. Summary: This review provides a comprehensive overview of currently available intravitreal tamponade agents, highlighting their indications, physical properties, clinical applications, and complications. Special attention is given to heavy tamponades, perfluorocarbon liquids, and recent developments in tamponade strategies. The article also explores future directions, including drug-eluting tamponades and the development of synthetic vitreous substitutes that aim to mimic the native vitreous body and reduce the need for postoperative interventions. Key Message: While current tamponade agents remain indispensable in vitreoretinal surgery, ongoing research into smarter, safer, and more physiologically compatible materials holds great promise. Future tamponades may not only offer mechanical support but also actively contribute to retinal healing and pharmacologic delivery, potentially transforming the standard of care in retinal surgery.
