Abstract:
The authors report the case of a 75-year-old man with preexisting glaucoma and recurrent retinal detachment who underwent intraocular silicone oil placement OD resulting in subsequent retrolaminar silicone oil migration to the optic chiasm and vision loss OS. MRI showed silicone oil tracking posteriorly along the right optic nerve to the chiasm. He was placed on high-dose corticosteroids and underwent a successful optic nerve sheath fenestration with improvement of vision in the contralateral eye. Clinicians should be cognizant of the potential for translaminar posterior migration of intraocular silicone oil, as well as the utility of optic nerve sheath fenestration to decompress the anterior visual pathways and restore vision.
