D’Amico YR 2003 UL http://www.ajnr.org/content/24/9/1769.abstract AB Summary: Perfluoro-n-octane (PFO) is a heavy liquid that is used as an aid for complicated retinal surgical procedures. Although PFO is usually removed intraoperatively, the radiographic appearance of retained PFO may mimic an intraocular foreign body or vitreous hemorrhage. As the use of PFO in retinal procedures has become more widespread, recognition of its imaging appearance has become important in the differential diagnosis of intraocular foreign body and ocular trauma.
