The results of Pars Plana Vitrectomy in patients with Intraocular Foreign Body

To identify the clinical features in eyes with intraocular foreign bodies (IOFBs) and evaluate the results of surgical management in these cases. In a descriptive retrospective study, the records of 32 eyes of 32 patients with IOFBs were reviewed. All eyes underwent pars plana vitrectomy between April 2001 and February 2012. The IOFBs were removed either with intraocular forceps or magnetic extraction. All patients were men with the mean age of 30.26 years. The average follows up period was 25.16 months. The IOFBS was ferromagnetic in 25 (70.5%). The IOFBs were extracted with external magnet in 17 eyes (50%) and with intraocular forceps in 12 eyes (35.2%). Macular pucker and scar were present in six eyes (18.7%). Final visual acuity was 20/40 or better in 7 eyes (21.9%) and 20/200 or better in 16 eyes (50%). There were no significant relationship between the final visual acuity of 20/200 or better and the site (P=0.59), size (P=0.53), type of IOFBs (P=0.39), and time interval between trauma and surgery (P=0.34). Although surgical management of IOFBs is a complicated procedure, the appropriate route of removal may be determined by the type, size and site of the embedded IOFB. The data from this study suggest no preference of the external magnet over intraocular forceps for extraction of magnetic IOFBs and the visual outcome was good.
