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 Ocular trauma also includes trauma to ocular adnexa and hence the terms IOFB and EOFB have been replaced by IGFB （intraglobal foreign body） and EGFB （extraglobal foreign body）.展开更多
