The aim of this study was to find out to which extent the instilled silicone oil affects the changes of lens, cornea, and the ocular pressure with regard to its time kept in the operated eye with a lens. The study was carried out on the sample of 40 patients, divided in three groups. The first group of patients with the silicone oil kept in the eye during 3 months, the second one during 3-6 mon...

OBJECTIVE To evaluate the outcome and complications of removal of silicone oil after pars plana vitrectomy. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Layton Rahmatullah Benevolent Trust (L.R.B.T), Free Base Eye Hospital, Karachi, from February 2008 to January 2011. METHODOLOGY Ninety five eyes of 95 patients with a history of undergoing three-port pars plana vitrectomy were in...

PURPOSE To compare anatomic and functional outcomes of macular hole surgery with either silicone oil or C(3)F(8) gas tamponade. DESIGN Retrospective comparative interventional study. PARTICIPANTS Fifty-four eyes of 51 patients underwent pars plana vitrectomy for macular holes. Thirty-one eyes were treated with silicone oil tamponade, and 23 eyes were treated with C(3)F(8) tamponade. METHO...

BACKGROUND The aim of the study was in vitro assessment and comparison of the antimicrobial activity of three types of silicone oils used in ophthalmic surgery. METHODS The silicone oils (Arciolane 1300 centistokes, Arciolane 5500 centistokes and Oxane Hd, heavy silicone oil) were inoculated with microbes common in endophthalmitis and their growth was observed continuously. Control tests of m...

BACKGROUND The debate over the legitimacy of silicone as a safe tool for soft-tissue augmentation has spanned well over half a century. Proponents concede that injections of questionable purity and/or of massive quantities have produced unfavorable outcomes. They assert that in experienced hands with "injectable-grade" silicone, there are very few problems. Despite these claims, the literature ...

PURPOSE To evaluate the outcomes of pars plana vitrectomy and silicone oil injection for the treatment of infectious endophthalmitis. METHODS 35 cases of endophthalmitis secondary to phacoemulsification (20 patients), trabeculectomy (8 patients), perforating trauma (2 patients), trauma (2 patients), corneal transplantation (1 patient), vitrectomy (1 patient) and corneal ulceration (1 patient)...

PURPOSE To determine and compare the refractive shifts based on Gullstrand-Emsley and Liou-Brennan schematic eyes after filling them with four selected artificial vitreous substitutes: silicone oil, heavy silicone oil, hydrogels, and encapsuled balanced salt solution. METHODS The optical constants of artificial vitreous body-filled eyes were calculated based on Gullstrand-Emsley and Liou-Bren...

Silicone oil continues to be an important aid in retinal detachment surgery. We report a case in which disparate responses to silicone oil were noted in the conjunctiva and intraocularly. Intraocularly, the oil permeated a fibrous membrane that formed behind a keratoprosthesis, the first example of this phenomenon. We detail the histological response to the oil at this site as well as a distinc...

BACKGROUND/PURPOSE To describe small hyper-reflective spherical bodies in sub-silicone oil-foveal depression (SSO-FD) space using spectral domain optical coherence tomography (SD-OCT) and its effect on visual outcomes in eyes undergoing silicone oil removal (SOR). METHODS This was a prospective interventional comparative study comprising 42 eyes undergoing SOR with clear media. All patients u...

PURPOSE To characterize the concordance/symmetry of each retinal layers in individuals without macular pathology and to further characterize the localization of inner retinal thinning in eyes receiving silicone oil-based endotamponade. METHODS Retinal layers of one hundred eyes of 50 individuals without macular pathology were imaged using spectral domain optical coherence tomography (SD-OCT) ...
