Foreign bodies (FBs) in the eye are usually classified as intraocular (IOFB) or extraocular (EOFB). In IOFB the FB is within the eye ball and in EOFB it is outside. This classification seems oversimplified. Hence a new classification is proposed on the basis of FB locations, in which adnexal FBs (in orbit, lids, con- junctiva and lacrimal apparatus) are also included. These are further classified according to their exact location. FBs can also be classified in many other ways. Besides IOFB and EOFB, another condition IMFB (intramural foreign body) is also described. The FBs are situated within cornea or sclera and are neither IOFB nor EOFB. Ocular trauma also includes trauma to ocular adnexa and hence the terms IOFB and EOFB have been replaced by IGFB (intraglobal foreign body) and EGFB (extraglobal foreign body).
眼内异物（FBs）通常分为眼内（IOFB）或眼外（EOFB）。在IOFB中，异物位于眼球内，而在EOFB中，异物在眼球外。这种分类似乎过于简单。因此，基于异物位置提出了一种新的分类方法，其中还包括附属器异物（在眼眶、眼睑、结膜和泪器中）。这些根据其确切位置进一步分类。异物也可以通过许多其他方式分类。除了IOFB和EOFB，还描述了另一种情况IMFB（壁内异物）。异物位于角膜或巩膜内，既不是IOFB也不是EOFB。眼外伤还包括眼附属器外伤，因此术语IOFB和EOFB已被IGFB（球内异物）和EGFB（球外异物）所取代。
