Objective:To assess the clinical setting of a heavy silicone oil tamponade(Densiron-68) for rhegmatogenous retinal detachment(RRD).Methods:Twenty-nine eyes of 29 consecutive patients were recruited between December 2007 and February 2009.Primary vitrectomy with Densiron-68 was used in all cases.Patients to be selected had two groups:one group had 18 cases

mean age was 72.5 years.These patients were impossible prone because of ages and body factors.Among these of 11 cases had macular holes and posterior pole part holes

another of 7 cases had many holes.Another group had 11 cases

mean age was 45.8 years.These patients with inferior complex rhegmatogenous retinal detachment with secondary proliferative vitreoretinopathy(PVR) were included.Besides one case of giant retinal tear with between 2 and 7 clock hours

among these of 7 cases had one or two scleral buckling procedure

or pars plana vitrectomy with oil endotamponade.But inferior recurrent retinal re-detachment appeared.Surgical techniques included pars plana vitrectomy

membrane peeling

heavy water application

endophotocoagulation

cryocoagulation

endotamponade et al.Results:1or 13-month follow up

mean 4.3-month.Densiron-68 removal with 25 cases was after operation of 2 months

and didn’t remove of 4 cases.After Densiron-68 removal

majority showed a stable reattached retina without further interventions

while

in one or two patients

recurrent retinal re-detachment appeared during Densiron-68 removal.Some of patients had partly lens opacification or lens post-capsular opacification.Part of patients had ocular hypertension.Conclusion:With Densiron-68

high anatomical and functional success rates can be achieved with inferior complex rhegmatogenous retinal detachment.Heavy silicone oil tamponade improves inferior tamponade

and may be considered a new generation of intraocular tamponades.But there were a significant early emulsification.Despite adequate Densiron fills

emulsification necessitated its removal.
