Popis: AIM: To provide comprehensive data on nonmetallic intraorbital foreign bodies (IOFBs) by summarizing and analyzing material types, clinical manifestations, imaging features, and treatment strategies. METHODS: Totally 28 nonmetallic IOFB cases treated at Shengjing Hospital of China Medical University from 2012 to 2020 were retrospectively reviewed. The types of foreign bodies, clinical features, imaging manifestations, and treatment outcomes were analyzed. RESULTS: Among all cases, 67.8% (19/28) of the foreign bodies were organic. The top three entrances were the upper eyelid skin (7/28), lower fornix conjunctiva (6/28), and lower eyelid skin (4/28). In most cases (11/28, 39.3%), foreign bodies remained in the medial orbits. The major clinical manifestations included eyelid redness and swelling (20/28, 71.4%), conjunctival congestion and edema (17/28, 60.7%), and ophthalmoptosis (15/28, 53.6%). Infection was the main complication, which occurred in 57.1% (16/28) of all cases. Computerized tomography (CT) values differed for different foreign bodies and varied in the different periods after injury. The plant- and grease-derived foreign bodies and the surrounding pus cysts showed different signals on magnetic resonance imaging (MRI). The prognosis varied with different foreign body types, surgery timing, and intraoperative management. CONCLUSION: The majority of nonmetallic IOFBs are organic and often remain in the superior, medial, and inferior areas of the orbit. Clinical manifestations vary owing to their different textures. CT and MRI facilitate the identification of foreign body materials. Plant-derived foreign bodies should be completely removed, and surgical treatment is a complicated process.
