Silicone oil is used as a long term intraocular tamponade in vitreoretinal surgery for conditions such as rhegmatogenous retinal detachments. Complications such as silicone oil associated keratopathy, cataract formation, or emulsification with secondary glaucoma have been reported.1 We report the unusual case of intracranial silicone oil migration with subsequent visual field defect in the fellow eye and the results of neurosurgical intervention

Case report

A 66 year old male patient had undergone cataract surgery and lens implantation on both eyes 20 months earlier. Six months after cataract surgery a retinal detachment was seen in the left eye which was first treated with pars plana vitrectomy and gas tamponade (15% C2F6). After a period of 4 months, a redetachment occurred and silicone oil (Acri.Sil-ol 5000, 5000 cps, Acri.Tec, Hennigsdorf, Germany) was used as a permanent tamponade. Postoperative visual acuity was 20/500 in the left eye. Twelve months later, the patient was referred to our institution for further evaluation of a temporal hemianopia of sudden onset in the right eye (fig 1A) and for treatment of elevated intraocular pressure in the left eye. At presentation, visual …
