To compare, through a randomized, multicenter surgical trial, the postoperative tamponade
effectiveness of intraocular silicone oil with that of an intraocular long-acting gas
(initially sulfur hexafluoride [SF 6 ], later perfluoropropane [C 3 F 8 ]) for the management
of retinal detachment complicated by proliferative vitreoretinopathy (PVR), using vitrectomy
and associated techniques.
To evaluate the ocular complications that result from the use of silicone oil and gas.
