pneumatic retinopexy
Pronunciation: /nuˈmætɪk ˌrɛtɪnoʊˈpɛksi/
Minimally invasive treatment for retinal detachment using gas injection and positioning therapy.
Full Definition
Pneumatic retinopexy is an office-based procedure for treating certain types of rhegmatogenous retinal detachment, particularly those with superior breaks. The technique involves injecting an expanding gas bubble (typically SF6 or C3F8) into the vitreous cavity, followed by precise patient positioning to allow the bubble to tamponade the retinal tear. Laser photocoagulation or cryotherapy is used to create a chorioretinal adhesion around the tear. Success depends on careful patient selection, appropriate break location, and strict adherence to positioning requirements during the gas absorption period.
Usage
Usage note: Emphasize positioning requirements and patient compliance factors in documentation.
