INTRODUCTION We introduce the use of low-molecular-weight silicone oil as an infusion and as a peroperative tool to facilitate three specific surgical steps, namely internal search for retinal breaks, vitreous base shaving and drainage of subretinal fluid. METHOD AND PATIENTS Ethics committee approval was obtained to test this novel agent in a small number of cases as a pilot study. Following...

OBJECTIVES To evaluate the safety and efficacy of active silicone oil removal with a 23-gauge (G) transconjunctival sutureless system. MATERIALS AND METHODS One hundred sixteen eyes of 113 patients who had previous retinal detachment surgery with pars plana vitrectomy and silicone oil injection surgery, and underwent silicone oil removal surgery with 23-G transconjonctival sutureless techniqu...

The expression of inflammatory mediators in the aqueous humor and the incidence of secondary glaucoma after vitreous body resection combined with silicone oil tamponade for patients with retinal detachment were inestigated, and the roles of IL-17, IL-6 and TNF-α in secondary glaucoma after silicone oil tamponade were analyzed. Fifty-eight cases of retinal detachment treated by vitrectomy combin...

The rheological properties of two non-polar liquids [silicone oil or perfluorinated oil (FC70)] containing various types of particles, barium titanate, nickel and iron-oxide, were investigated as functions of solid loading, particle size and shear rate. All the particles were synthesised in-house. The viscosities of either silicone oil or FC70 containing different solid loadings (10, 20 and 30 ...

AIM To determine a suitable intraocular lens for implantation in patients at high risk of lens exposure to silicone oil in their lifetime. METHODS PMMA, AcrySof, AR40, AQUA-Sense, and Raysoft lenses were examined. Each lens was immersed for 5 minute intervals in balanced salt solution (BSS), in stained silicone oil, and again in BSS before being photographed in air and in BSS. Percentage sili...

Turbine oil plays an important role in supporting optimal steam turbine performance. Some additives in turbine oil can cause emulsification when the oil is contaminated by water, so demulsibility is a very important property of the steam turbine oil. In order to improve the demulsibility of steam turbine oil, two kinds of polyether-silicone comb copolymers are synthesized and used as steam turb...

Silicone-oil additives are often used in fouling-release silicone coatings to reduce the adhesion strength of barnacles and other biofouling organisms. This study follows on from a recently reported active approach to detach barnacles, which was based on the surface strain of elastomeric materials, by investigating a new, dual-action approach to barnacle detachment using Ecoflex®-based elastome...

AIM To report anatomic and visual outcomes following silicone oil removal in a cohort of patients with complex retinal detachment, to determine association between duration of tamponade and outcomes and to compare patients with oil removed and those with oil in situ in terms of demographic, surgical and visual factors. METHODS We reported a four years retrospective case series of 143 patients...

Long-term assessment of eyes in which silicone oil injection had been used in the treatment of retinal detachment with massive preretinal retraction was undertaken in 92 consecutive patients. While a high incidence of complications, particularly cataract, was confirmed, this study showed that they were probably caused not by any toxic effect of silicone oil but by obstruction of normal metaboli...

The aim of this prospective study was to determine the possible influence of the silicone oil tamponade after vitrectomy on the early intraocular pressure (IOP) elevation, which is a major risk factor for developing secondary glaucoma in patients with vitreal and retinal proliferative changes. The research included 110 patients which were allocated in three groups according to the medical histo...
