Intra-ocular silicone oil has been used as a vitreous replacement and for internal tamponade of complex retinal detachments.
Some reported side effects include glaucoma and corneal decompensation 1.
CT
Hyperattenuating on unenhanced CT with a reported average CT unit value of around 130 2. It appears well-defined and generally of homogeneous density.
MRI
Migration of silicone outside ocular globe (e.g. intracranial - rare 5)
In some situations, it may mimic a vitreous hemorrhage on CT.
