Silicone oil use as an adjunct to complicated vitreoretinal surgery is becoming more frequent. Refractory glaucoma in these patients is common. Isolated reports have mentioned the possibility of silicone oil migrating and/or obstructing the tube in the anterior chamber of Molteno implants (IOP, Costa Mesa, Calif). This report describes a case of intraocular silicone oil egressing through an Ahm...

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...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016217023 DESCRIPTION A 77-year-old woman underwent pars plana vitrectomy for recurrent retinal detachment with silicone oil injection 10 years before presentation. Also the patient was placed on antiglaucoma medications. The patient had a history of recurrent corneal ulcerations in both eyes du...

PURPOSE To describe vision loss associated with the use or removal of silicone oil retinal tamponade. METHODS Records were reviewed of all patients with a decrease in visual acuity of at least 3 Snellen lines from best acuity with 5000 centistoke silicone oil in place or after removal of silicone oil at a single retina-only practice between 1996 and 2006. RESULTS Nine patients (6 men, 3 wom...

AIM Heavy silicone oil removal can be challenging and differs considerably from conventional oil. Traditionally, strong active aspiration had to be applied through a long 18G needle just above the optic disc. We present a novel technique using a much shorter (7.5 mm) and smaller (20G) needle allowing its removal "from a distance." METHOD Active aspiration on a vacuum of 600 mm Hg of the "visc...

BACKGROUND To describe one modified method of having machine-independent removal of 5,000 centistokes silicone oil through 23-gauge trocar-cannulas. METHODS Consecutive patients with silicone oil tamponade for more than four months and with complete retinal reattachment were included. Two 23-gauge trocars were used to make sclerotomies while the microcannulas remained in situ for intravitreou...

PURPOSE To demonstrate development and complications in heavy silicone oil (HSO) surgery in 100 eyes following primary vitreoretinal surgery. METHODS 100 eyes were included in this retrospective study that underwent vitreoretinal surgery using HSO as endotamponade. Indication diagnoses were retinal detachments (n = 76), complicated macular holes (MH) (n = 20), and others (n = 4). HSO removal ...

INTRODUCTION To report a case in which intraocular silicone oil migrated into the upper eyelid and caused ptosis. METHODS A 65-year-old woman presented with proliferative vitreoretinopathy in the right eye. Vitrectomies, injection of silicone oil and encircling were performed. Two months after the last operation, swelling of her right eyelid occurred. RESULT Magnetic resonance imaging revea...

PURPOSE To study the in vitro effect of silicone oil of different viscosities and liquid perfluorocarbons on platelet aggregation. METHODS Silicone oil with a viscosity of 5700 cs and 1000 cs and liquid perfluorocarbons of perfluoroperhydrophenantren and perfluorodecaline were studied to investigate the effect of these agents on platelet aggregation under in vitro conditions. The experiments ...

During an investigation into the use of oil emulsions in foliar sprays, it was found that silicone oil emulsions accelerated the senescence of the primary leaves of bean (Phaseolus vulgaris) plants. It was shown that accelerated senescence was not a result of the reduced transpiration rates found in silicone-sprayed leaves. Furthermore, the silicone oil emulsions did not induce leakiness in pla...
