title: Management of posterior segment foreign bodies and long-term results.
abstract: The management of 158 posterior segment intraocular foreign bodies (IOFB) was retrospectively analyzed: transscleral magnet extraction via the pars plana was used for 40 magnetic IOFB, transscleral extraction via the IOFB bed for 35 magnetic and 4 non-magnetic IOFB, pars plana vitrectomy (PPV) for 44 magnetic and 32 non-magnetic IOFB, and open-sky vitrectomy for 3 non-magnetic IOFB. Final visual acuity of 0.02 and better was achieved in 104 out of 119 magnetic IOFB (87%) and 24 out of 39 non-magnetic IOFB (62%), and final visual acuity 0.05 and better in 79 magnetic IOFB (66%) and 17 non-magnetic IOFB (44%). Transscleral extraction via the IOFB bed under ophthalmoscopic control and IOFB removal by PPV proved to be the operations of choice for an increasing number of IOFB. For magnetic IOFB, these techniques yielded better final functional results than transscleral magnet extraction via the pars plana. Final visual acuity did not depend on the interval between injury and IOFB removal, and with regard to the risk of endophthalmitis, IOFB need not be considered an absolute indication for immediate intervention. IOFB size up to 5 mm2 and initial visual acuity of 0.5 and better were significant positive factors for both magnetic and non-magnetic IOFB.
