tamponade
Pronunciation: tam-pon-AHD
The use of gas, oil, or other substances to provide internal support and pressure during retinal reattachment surgery.
Full Definition
Tamponade refers to the surgical technique of filling the vitreous cavity with a substance that exerts pressure against detached retinal tissue, promoting reattachment and healing. Common tamponade agents include various gases (SF6, C3F8), silicone oil, and heavy liquids like perfluorocarbon compounds. The choice of tamponade depends on the specific pathology, required duration of support, and patient factors such as the ability to maintain proper head positioning. Gas tamponades gradually absorb over time, while silicone oil may require subsequent removal surgery.
Usage
Usage note: Specify the type of tamponade agent used (gas, oil, etc.) in surgical documentation.
