The intestinal absorption of silicone fluid 703, a methyl phenyl polysiloxane, has been studied in the rat. This silicone was chosen for the present investigation because of its lipid-like character and its solubility in olive oil. The experimental findings demonstrate that very little, if any, silicone is absorbed when fed in olive oil. No silicone was found in the lymph lipids of cannulated r...

Aims—To evaluate the eVect of trans scleral cyclophotocoagulation (TSCPC) on intraocular pressure (IOP) in the eyes retaining intravitreal silicone oil with medically uncontrolled secondary glaucoma following intravitreal silicone oil injection. Methods—Medical records of 11 eyes of 11 patients who underwent TSCPC for medically uncontrolled glaucoma without pupillary block following intravitrea...

The purpose of this study is to evaluate the anatomic and visual outcomes, as well as the complications, of macular hole surgery with SF6-gas tamponade versus silicone-oil tamponade. Fifty-four (54) eyes with idiopathic macular hole underwent vitrectomy and peeling of the internal limiting membrane (ILM) around the hole. Nineteen (19) eyes were treated with SF6-gas tamponade (group 1) and the o...

Purpose To evaluate refractive status and identify predictors of surgical success following a combined silicone oil removal/cataract surgery with intraocular lens (IOL) implantation procedure. Methods In this single-armed, retrospective study, we reviewed patients who underwent vitreoretinal surgery followed by a combined silicone oil removal/cataract surgery procedure between 2009 and 2013. ...

The efficacy of two novel artificial vitreous body substitutes (VBS) consisting of highly biocompatible thiolated cross-linked hyaluronic acid (HA)-based hydrogels in comparison to silicone oil in a model of retinal detachment was investigated. Pars plana vitrectomy (23G) was performed in the right eye of 24 pigmented rabbits. Retinal detachment of two quadrants was induced by creating a small ...

PURPOSE To assess anatomic outcomes following repair of traumatic retinal detachment (RD) among a cohort of cognitively impaired adolescents with self-injurious behaviors. METHODS Main outcome measures in this retrospective, consecutive, interventional case series were retinal attachment and postoperative complications. RESULTS Complete retinal reattachment was initially achieved in all 9 e...

Silicone oil has been the only long-term vitreous substitute used in the treatment of retinal detachment since 1962 by Cibis. Nevertheless, its effects on retinal vascular morphology and oxygen supply to the retina are ambiguous in current research. We previously invented a foldable capsular vitreous body (FCVB) to use as a new vitreous substitute in the treatment of severe retinal detachment, ...

PURPOSE To evaluate the midterm anatomical and functional outcomes of intravitreal injection of low-dose triamcinolone acetonide in silicone oil-filled eyes as an adjunctive treatment for proliferative vitreoretinopathy. METHODS This is a retrospective interventional case series. Patients with proliferative vitreoretinopathy grade C or D received pars plana vitrectomy combined with silicone o...

PURPOSE To report the short-term efficacy and safety of the transfer of an Ahmed(™) glaucoma valve (AGV™) tube from the vitreous into the anterior chamber, in a patient with neovascular glaucoma who had undergone pars plana AGV(™) implantation and ultimately needed a silicone oil tamponade. CASE A 41-year-old male with proliferative diabetic retinopathy in both eyes was referred to us for tre...

Purpose. Retinal redetachment of silicone oil-filled eyes continues to be a frustrating condition that typically requires retinectomy. We proposed radial retinotomy as a potentially less invasive surgery. Here, we preliminarily explored its feasibility, efficacy, and safety. Methods. Totally 9 eyes of 9 consecutive patients were included in a prospective noncomparative trial. A series of retino...
