Silicone oil is preferred over C3F8 gas as intraocular tamponade in which specific situation?
- A Giant retinal tear with associated proliferative vitreoretinopathy grade C ✓
- B Uncomplicated macular hole with no PVR
- C Phakic patient with superior rhegmatogenous RD
- D Macular pucker with lamellar hole
Correct answer: A. Giant retinal tear with associated proliferative vitreoretinopathy grade C
Explanation
Silicone oil is the preferred tamponade in complex retinal detachments with proliferative vitreoretinopathy (PVR) grade C or higher, giant retinal tears with PVR, and cases where the patient cannot maintain positioning or needs to travel by air (gas tamponade is contraindicated with air travel due to expansion). C3F8 gas is adequate for uncomplicated cases but is absorbed after 6–8 weeks and cannot provide long-term tamponade needed in severe PVR.
