Problems and Timing in the Removal of Silicons Oil

Efficacy and safety of heavy silicone oil Densiron 68® in the treatment of complicated retinal detachment with large inferior retinectomy

“…With such tamponades, however, an increased rate of recurrent detachment has been observed in eyes with inferior RD or detachments operated on by large inferior retinectomy. This is often due to retinectomy reopening and reproliferation in the inferior part of the retina [10,11,23,24,27,28]. At the end of the 1990s, this recurrence led to the development of heavy silicone oils, a new group of tamponade agents with a specific gravity greater than that of water.…”

The adherence of silicone oil to standard and heparin-coated PMMA intraocular lenses

“…Oil removal is associated with a significant risk of retinal re-detachment.1A 6 Further surgery for re detachment may be more difficult if the integrity of the globe is weakened by a recent cataract incision. Combined oil removal with lens implantation also leads to added complications such as formation of posterior synechiae, pupil capture of the IOL optic, accelerated posterior cap sule opacification and pupil block glaucoma.…”

“…These com plications may be more common in patients with diabetes mellitus. 7 Kampik et al 6 reported performing combined oil removal with extracapsular cataract extraction and IOL implantation (ECCE/IOL) in 30 eyes but did not comment on the complications; nevertheless, combined surgery was recommended. Removing silicone oil and performing cat aract extraction as separate procedures will avoid contact of the IOL with the oil.…”

Outcomes of Retinectomy of 180° or more in Retinal Detachment with Advanced Proliferative Vitreoretinopathy

“…4,30,38 Kampik et al have reported better anatomical outcomes with prolonged duration of tamponade in cases of advanced PVR. 39 Since, all our cases had advanced PVR (PVR D), duration of tamponade was longer and silicone oil removal was considered after at least 1 year follow-up or earlier if there were complications.…”
