Ocular tolerance and efficacy of short-term tamponade with double filling of polydimethyloxane and perfluoro-n-octane

Abstract: Double filling tamponade was performed in 30 eyes of 30 patients by 30% perfluoro-n-octane and 70% RS-OIL 1000 cS for an average of 23 days, after expanding the vitreous cavity with HPF10 perfluorodecalin.

The follow-up visits were scheduled 1 week, 1 month, and 3 months after surgery. The main outcome measures were visual acuity, intraocular pressure (IOP), PVR reproliferation, and electrophysiological parameters.

The primary success rate was 80% (24/30). Fourteen patients (46.7%) had a postoperative improvement in visual acuity, 12 patients (40.0%) maintained their preoperative visual acuity, and four patients (13.3%) experienced a reduction in visual acuity. In conclusion, our experience with double filling in selected cases of retinal detachment was positive.

No electroretinographic signs of retinal toxicity and a low incidence of PVR reproliferation were observed.
