tamponade
Pronunciation: tam-pon-ADE
Substance placed inside the eye during retinal surgery to maintain tissue positioning and facilitate healing. Common agents include gas, silicone oil, or balanced salt solution.
Full Definition
A therapeutic agent introduced into the vitreous cavity during retinal surgery to provide internal pressure and maintain anatomical positioning of detached or surgically manipulated retinal tissues. Different tamponade agents serve specific purposes: gas bubbles provide temporary support and gradually reabsorb, silicone oil offers longer-term support for complex cases, and balanced salt solution maintains volume during surgery. Selection depends on surgical objectives, patient positioning requirements, and expected healing timeline. Patient positioning restrictions and follow-up schedules are significantly influenced by tamponade choice.
Usage
Usage note: Always specify agent type and concentration in surgical documentation.
