cone oil placement and onset of discomfort may be explained by long-term, slow leakage of silicone oil through the sclera. Free silicone oil within the extracellular matrix commonly causes a chronic granulomatous reaction that may lead to inflammation or functional impairment. Our patient described late development of ocular and orbital pain in a blind eye treated with silicone oil. Enucleation...

In order to improve the homogeneity and dispersity of the sericite in methylphenyl-silicone resin, the agglomerate state of the sericites was controlled effectively. The dispersive model of the sericite in methylphenyl-silicone resin was designed also. First, the modified sericite was prepared using hexadecyl trimethyl ammonium bromide as the intercalating agent. Then, functional sericite was i...

AIMS/BACKGROUND Recurrent peripheral retinal detachments may occur in eyes treated with vitrectomy and silicone oil for retinal detachments complicated by proliferative vitreoretinopathy (PVR). The aim of this study was to assess whether laser photocoagulation could be used in the presence of silicone oil to confine and stabilise recurrent PVR related peripheral retinal detachments enabling the...

BACKGROUND Silicone catheter insulation, larynx prostheses undergo biodegradation. The aims of the study were to verify the conviction that outer silicone lead insulation is biostable and inert in addition to determining the role of macrophages (M) and Staphylococcus aureus (S aureus) strains in the silicone lead insulation degradation. METHODS AND RESULTS Leads removed from 8 patients becaus...

Liquid silicone is inexpensive, minimally antigenic, and likely noncarcinogenic. Its simplicity of use has made it popular as a soft-tissue filler in some parts of the world for patients seeking rapid soft-tissue augmentation of the face, breast, and buttocks. However, multiple reports describe the complications of silicone injections such as cellulitis, abscess, ulceration, and foreign body mi...

BACKGROUND Patients with Rhegmatogenous retinal detachment develop raised intraocular pressure (IOP) when they undergo pars plana vitrectomy with silicone oil. The present study was done to document changes in IOP with silicone oil and after its removal. METHODS The interventional study was conducted at Eye department of Lady Reading Hospital Peshawar, from August 2012 to July 2014 on 30 pati...

wetability of biocompatible polymers can be improved by plasma surface modification. the purpose of this study was to surface modify an experimental poly (dimethylsiloxane) rubber (pdms) material in order to improve its wetability and biocompatibility. surface properties of the pdms were characterized using contact angles measurement for wetability analysis. samples of experimental silicone rub...
