Management of Intraocular Foreign Bodies of Posterior Segment

Abstract

Purpose: to study the epidemiological and clinical characteristics of penetrating wounds with intraocular foreign bodies (IOFB) and to discuss different timing and surgical techniques related to the extraction of the foreign body. Methods:We collected information from the files of 60 patients hospitalized for penetrating wound with metallic IOFB over a period of 10 years from 2010 to 2020. All patients underwent vitrectomy and extraction of the IOFB immediately after the first consultation. Results:The age ranged from 3 to 90 years with a predominance of males. The circumstances were dominated by work accidents (58.33%). The IOFB was metallic in 75%. The size of the IOFB varied from 1 to 30 mm with a median of 5.39 mm. The preoperative visual acuity varied between 8/10 and light perception. The postoperative visual acuity depended of the primary visual acuity and the evolution. Conclusion:At the end of this study, our results testify to the severity and seriousness of these ocular injuries and show that prevention remains a fundamental element in the management of penetrating wounds with IOFB, not only in the workplace but also in the home.

Ophthalmic Trauma-Related Instruments—Critical Tools for Winning the Case

“…10,13 Therefore, internal removal with PPV is preferred, and external removal should be avoided. 10,13,14 Illumination during IOFB removal is a critical component to consider during surgical planning. Often, regardless of the instrument used to remove the IOFB, a bimanual technique is required due to the irregular shape and orientation of the object and its natural tendency to fall back.…”
