Transscleral Extraction of an Intraocular Foreign Body from the Posterior Segment of the Eye without Pars Plana Vitrectomy.

Abstract

Penetrating eye trauma with an intraocular foreign body is very frequent, especially in men in their productive age. Pars plana vitrectomy would be the standard surgical method at our department. However, in indicated cases (metallic intraocular bodies in the posterior eye segment in young patients with well transparent ocular media without detached ZSM and without any evident vitreoretinal traction) transscleral extraction of the intraocular foreign body is performed using the exo magnet, eventually endo magnet with aminimal PPV without PVD induction under the visual control of endo-illumination. Between June 2003 and June 2018, 66 eyes of 66 patients diagnosed with apenetrating eye trauma caused by an intraocular foreign body located in the posterior eye segment were treated. In 18 eyes (27,3 %) with ametallic foreign body in vitreous (body) or in retina, no PPV or aminimal PPV without PVD was used as asurgical method. In the remaining 48 eyes (72,7 %), astandard 20G, respectively 23G PPV method were used together with PVD induction and the foreign body extraction via endo or exo magnet. As demonstrated by our survey/study, in the cases of athoroughly considered indication an experimented vitreoretinal surgeon can perform asafe NCT transscleral extraction from the posterior eye segment via exo magnet, eventually endo magnet under the visual control of acontact display system with aminimal PPV. Thereby, the surgeon can enhance the patient´schance to preserve their own lens and its accommodative abilities as well as reduce the risk of further surgical interventions of the afflicted eye.
