We describe the benefits of perfluoro-N-octane (PFO), a perfluorocarbon liquid, in the removal of nonmagnetic intraocular foreign bodies (IOFBs) from the macula and posterior segment. Two consecutive cases of posterior segment IOFB were reviewed. An 18-year-old male presented to the emergency room after a motor vehicle accident with a zone 1 open globe injury and large glass IOFB in the left eye. A 53-year-old male presented to the emergency room with a history of a 3-week delayed presentation of a zone 1 open globe injury from a nail to the right eye. He was found to have a metallic IOFB. In both cases, PFO was used to slide the nonmagnetic IOFBs outside of the macula for safer retrieval. PFO was also able to protect the posterior pole from IOFB drops during early attempts at removal. PFO can be a useful surgical adjunct to pars plana vitrectomy in the removal of certain nonmagnetic IOFBs.
我们描述了全氟正辛烷（PFO），一种全氟化碳液体，在从黄斑和眼后段取出非磁性眼内异物（IOFBs）方面的益处。回顾了两例连续的眼后段IOFB病例。一名18岁男性在机动车事故后因左眼1区开放性眼球损伤和大玻璃IOFB被送往急诊室。一名53岁男性因右眼被钉子扎伤导致1区开放性眼球损伤延迟3周就诊而被送往急诊室。发现他有一个金属性IOFB。在这两例病例中，PFO被用于将非磁性IOFB滑至黄斑外以便更安全地取出。在早期取出尝试过程中，PFO还能够保护后极免受IOFB掉落的影响。在取出某些非磁性IOFB时，PFO可以作为玻璃体切除手术的一种有用辅助手段。
