A combined technique of extracapsular cataract extraction and silicone oil injection is described. The anterior capsule is preserved to prevent movement of the silicone oil from the vitreous cavity to the anterior chamber. An anterior chamber tap ensures that the vitreous cavity is completely filled with silicone oil, while a peripheral iridectomy prevents postoperative pupillary block glaucoma.

PURPOSE To report causes of failure, management options, and outcomes after reoperations for recurrent retinal detachment in silicone oil-filled eyes. METHODS One hundred eighteen silicone oil-filled eyes with recurrent retinal detachment were managed with revision of vitrectomy with membrane surgery with or without silicone oil removal, just scleral buckling, or both. Anatomical success was ...

BACKGROUND Characteristic complications have been reported for transconjunctival sutureless vitrectomy, such as postoperative sclerotomy leakage and postoperative hypotony. Particular attention to sclerotomy closure is required in cases of silicone oil tamponade, because postoperative supplementation of silicone oil implies reoperation, whereas postoperative supplement of gas is comparatively e...

In the aphakic eye, with intact iris diaphragm, silicone oil has frequently caused a pupillary block. In this situation aqueous humour accumulates behind the iris and forces silicone oil through the pupil into the anterior chamber. An iridectomy at the 6 o'clock position can effectively prevent this pupillary block. The iridectomy allows free passage of aqueous to the anterior chamber which rem...

PURPOSE To evaluate the tamponade effect on the retina of a heavier-than-water silicone oil mixture and to compare it with the effect of silicone oil. METHODS Prospective, non-randomised, comparative pilot study. Phakic/pseudophakic patients with retinal detachment undergoing vitrectomy with Densiron 68 or silicone oil were recruited. The 'separation volume', defined as the relative volume of...

OBJECTIVE To investigate the outcome of rhegmatogenous retinal detachment repair at Vitreoretinal unit of Jinnah Post Graduate Medical Centre Karachi in year 2014. METHODS One hundred and three eyes of one hundred and three patients, who underwent three ports parsplana vitrectomy + band + silicone oil, three ports pars plana vitrectomy + silicone oil, three ports pars plana vitrectomy + C3F8 ...

PURPOSE To evaluate the effects of long-term tamponade with silicone oil on retinal saturation. METHODS A total of 49 eyes that received tamponade with silicone oil were included. The patients were divided into 3 groups (3-6 months, 6-9 months, and >9 months) according to the duration of silicone oil tamponade. Retinal oximetry was performed using the Oxymap system before and 2 months after s...

PURPOSE To estimate localization and the period up to the appearance of small hyperreflective round-shaped droplets using spectral-domain optical coherence tomography (SD-OCT) after pars plana vitrectomy with silicone oil tamponade. METHODS A retrospective observational study included 24 patients who had undergone pars plana vitrectomy with silicone oil tamponade for proliferative vitreoretin...

Intracranial silicone oil is a rare complication of intraocular endotamponade with silicone oil. We describe a case of intraventricular silicone oil fortuitously observed 38 months after an intraocular tamponade for a complicated retinal detachment in an 82 year-old woman admitted in the Department of Neurology for a stroke. We confirm the migration of silicone oil along the optic nerve. We dis...

AIM To examine the histology of preserved anterior lens capsule in vitrectomised and lensectomised rabbit eyes with and without silicone oil tamponade. METHODS Forty adult Japanese albino rabbits received two port vitrectomy and lensectomy with or without silicone oil tamponade in one eye under both general and topical anaesthesia. Anterior lens capsule was preserved during operation. After h...
