Perfluoro-n-butane. A gas for a maximum duration retinal tamponade.
Archives of Ophthalmology (Chicago, Ill. : 1960)
|March 1, 1983
Summary
Perfluoro-n-butane gas shows promise for long-term retinal detachment repair. This gas expands significantly and remains in the eye for over three months, outperforming previously reported gases.
Area of Science:
- Ophthalmology
- Biomaterials Science
Background:
- Retinal detachment surgery requires effective vitreous tamponade.
- Current tamponade gases have limitations in duration and expansion.
Purpose of the Study:
- To evaluate perfluoro-n-butane (C4F10) as a potential long-term intravitreal tamponade.
- To compare its expansion and retention properties with existing gases.
Main Methods:
- A 0.3-mL bubble of perfluoro-n-butane was injected into the rabbit vitreous.
- Gas expansion, volume changes, and duration were monitored over time.
Main Results:
- Perfluoro-n-butane expanded five times, displacing the entire vitreous within three days.
- The gas bubble remained substantial for over three weeks.
- Total disappearance time exceeded three months.
Conclusions:
- Perfluoro-n-butane demonstrates superior expansion and prolonged retention in the vitreous.
- Its properties suggest significant potential as a long-term tamponade for retinal detachment surgery.
