“…To our knowledge, only 22 cases have been previously reported. 3 -23 Of these cases, 11 patients also had an ocular history of diabetic retinopathy, 2 had CMV retinitis, and 1 had a history of uveitis (Table 1). The others were presumed to have had retinal detachment uncomplicated by other intraocular disease.…”

“…Since this complication is rare and most patients are relatively asymptomatic on presentation, surgeons have found no reason to intervene in patients with SO migration beyond conservative management and observation. 4,5,13,15,37 In most cases, patients with intraventricular SO who presented with symptoms were successfully treated with conservative management. In these cases, patients initially underwent neuroimaging as part of the workup of symptoms such as headache or dizziness (Table 1).…”

“…3 To our knowledge, 21 additional cases have since been reported in the literature. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Additional studies have reported SO migration to the optic nerve. 22,[24][25][26][27][28][29][30] Here we present a similar case of intravitreal SO migration into the lateral cerebral ventricles and propose potential mechanisms for how SO migrates upstream to this location via cerebrospinal fluid (CSF) flow from the optic nerves.…”

Purpose: Silicone oil (SO) is often used as an intraocular tamponade in repairs of retinal detachments. It may be associated with complications such as cataract, glaucoma, keratopathy, subretinal migration of oil, fibrous epiretinal and sub retinal proliferations, and oil emulsification. The purpose of this report is to describe a rare phenomenon of intraocular silicone oil migration into the cerebral ventricles, which may later be mistaken for intraventricular hemorrhages on neuroimaging. Methods: Case report with literature review. Results: A patient with a history of retinal detachment repair with intraocular SO presented with headaches. Neuroimaging revealed SO migration to the cerebral ventricles. The patient was treated conservatively with symptom management and headaches resolved. Conclusions: We present a case of intraocular SO migration to the cerebral ventricles and review the current literature. We also propose two mechanisms for this phenomenon.

BACKGROUND AND PURPOSE: Intraocular silicone oil injection has been used to treat complicated retinal detachments, and recently its retrolaminar and intracranial migration has been reported. The purpose of this study was to document the prevalence of posterior migration of intraocular silicone oil on head CT and describe the clinical and radiologic findings. MATERIALS AND METHODS: This retrospective study included 57 patients with intraocular silicone oil injection who underwent unenhanced head CT between November 2008 and July 2018. All images were visually evaluated for subretinal and retrolaminar migration of intraocular silicone oil involving the anterior visual pathway (optic nerve, optic chiasm, and optic tract) and the ventricular system. Attenuation values of those structures were measured and compared with those of the contralateral or adjacent normal structures. RESULTS: We detected subretinal and retrolaminar silicone oil migration in 7 of the 57 patients (12%), noting silicone oil at the optic nerve head (n = 2), retrolaminar optic nerve (n = 5), optic chiasm (n = 3), optic tract (n = 3), and in the lateral ventricles (n = 1). Attenuation values of the structures with silicone oil migration were significantly higher than those of the control regions (optic nerve head, 69.
