(A) Temporal hemianopia of the right eye. Visual acuity was 20/20. (B) The optic disc of the left eye shows atrophy and glaucomatous damage, the cup-disc ratio is 1.0. Note the reflex on the retinal surface, caused by the silicone oil tamponade. (C) Axial T1 weighted MRI scans demonstrate intraocular silicone oil (S) which is hyperintensive compared to the normal vitreous (V). Note the hyperintensive signal in the area of the intracranial portion of the optic nerve and the chiasm (arrow). (D) T2 weighted scans demonstrate hypointensive signals in the silicone filled eye (S) as well as in the area of the optic nerve and chiasm.

(A) Left optic nerve (ON) before incision. Arrows point at translucent thinned perineural sheath with silicone oil beneath. OC, entrance to optic canal; ICA, internal carotid artery. (B) Silicone oil (arrow) evading from left optic nerve after incision of perineural sheath. (C) View into left optic nerve after complete removal of the silicone oil. The nerve has been hollowed out by the oil with just thin nerve walls remaining. (D) After intracranial surgery, a regression of the visual field defect was observed.
