Purpose: 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 a minimal PPV without PVD induction under the visual control of endo-illumination. Materials and Methods: Between June 2003 and June 2018, 66 eyes of 66 patients diagnosed with a penetrating eye trauma caused by an intraocular foreign body located in the posterior eye segment were treated. In 18 eyes (27,3 %) with a metallic foreign body in vitreous (body) or in retina, no PPV or a minimal PPV without PVD was used as a surgical method. In the remaining 48 eyes (72,7 %), a standard 20G, respectively 23G PPV method were used together with PVD induction and the foreign body extraction via endo or exo magnet. Conclusions: As demonstrated by our survey/study, in the cases of a thoroughly considered indication an experimented vitreoretinal surgeon can perform a safe NCT transscleral extraction from the posterior eye segment via exo magnet, eventually endo magnet under the visual control of a contact display system with a minimal PPV. Thereby, the surgeon can enhance the patient´s chance to preserve their own lens and its accommodative abilities as well as reduce the risk of further surgical interventions of the afflicted eye.

Firecracker induced open globe injury is a big challenge for ophthalmic surgeons. Its associationwith the intraocular foreign body makes the diagnosis and treatment even more difficult resultingin poor anatomical and visual outcomes. We report a case of a 35-year-old male who presented withbilateral, multiple corneal and intraocular foreign body due to firecracker explosion. His vision waslimited to hand movement in both eyes. Combined penetrating keratoplasty and cataract surgerywere done in both eyes followed by pars plana vitrectomy for intraocular foreign body removal.The final best-corrected visual acuity of the patient stood to be 6/6 and 6/9 in the right and left eyerespectively. The encouraging result in our case prompts ophthalmologists for a timely stepwisemultidisciplinary approach in all open globe injuries with intraocular foreign body cases havingpoor initial acuity.

Introduction: Posterior segment retained Intraocular foreign body (IOFB) management is challenging. Facility of pars plana vitrectomy (PPV) and availability of well trained vitreo retina surgeons are the basic need to accomplish this work.  Encircling band provide permanent 360° support to close the anterior retinal break and prevent traction on the retina. The objective of this study is to analyse the clinical characteristics and predictors of the final visual outcome and survival of the globe in cases of retained IOFB in the posterior eye segment. Materials and methods: A hospital based retrospective observational study was conducted. All the patients of retained IOFB in the posterior segment presented from January 2016 to June 2019 were enrolled. Patients presented with visual acuity of NPL were excluded. Statistical analysis was performed using a variety of tests using SPSS version 21.   Results: Forty eyes of 40 patients were included. The mean age was 27.08±10.68 years (range 5-66). 95% of our patients were male. Most of them (52.5%) worked on the farm. 26(65%) of 40 eyes had Zone I injury. The median time spent before presentation was 13.5 day. Retinal detachment, vitreous hemorrhage, and endophthalmitis were present in 15, 23 and 5 eyes, respectively, before IOFB removal. The mean LogMAR visual acuity was improved significantly from 2.50±0.87 to 1.33± 1.01 (p=0.003). Poor presenting visual acuity, retinal detachment and large diameter of IOFB were found as the predictor of poor final visual acuity. Conclusion:  Pars plana vitrectomy by a vitreo retinal surgeon can give encouraging results in the cases of retained posterior segment IOFB. Poor presenting visual acuity, large diameter of IOFB and RD before IOFB removal are predictors of poor visual outcome.

Traumatic ocular injury is an uncommon yet leading cause of monocular blindness among the working-age group. Retained intraocular foreign body (IOFB) are associated with 41% of open globe injuries. Pars plana vitrectomy is often required for posterior segment IOFB removal. Advances in vitreoretinal surgical techniques and instrumentation have resulted in better treatment outcomes with reduced ocular morbidity. We report a case of modified ILM forceps with perfluorocarbon liquid-assisted non-magnetic IOFB removal in a young man after a motor vehicle accident with zone one open globe injury and a large glass IOFB in the right eye. We describe the use of perfluoro-N-octane to slide the IOFB extramacularly and reorient the IOFB plane for stable and safe retrieval by ILM end-gripping forceps. The modified design of the ILM end-gripping forceps with adjunctive use of perfluorocarbon liquid in pars plana vitrectomy reduces slippage during IOFB extraction and prevents collateral iatrogenic retinal injury.

Introduction. An intraocular foreign body may traumatize the eye mechanically, introduce infection or exert other toxic effects on the intraocular structures. Removal of a metallic intraocular foreign bodies (IOFB) use an internal (vitrectomy followed by forceps or internal magnet use) or external approach (large electromagnet). Outline of Cases. A 51-year-old man sustained injury of the left eye by a metal foreign body. On admission visual acuity was normal (VOS=1.0) and intraocular tension was within normal limits (TOS=10 mmHg). Nasal scleral entry wound was noticed. Ultrasound of the left eye was done, which confirmed existence of IOFB laying nasally, next to the ciliary body. Extraction of IOFB with a big electric magnet was done. Visual acuity on discharge was the same (VOS=1.0). Another man, aged 30 years, came to the clinic after injury of the left eye by a foreign body. On admission visual acuity was VOS=L+P+ (light and projection), TOS=44 mmHg (higher), traumatic cataract, scleral entry wound, corneal edema, existence of IOFB and initial endophtalmitis. Lensectomia and vitrectomia via pars plana with IOFB extraction were done. Visual acuity on discharge was VOS=5/60 with +6.50 Dsph = 0.3-0.4; TOS=17 mmHg. Conclusion. Magnet removal is indicated in patients when IOFB is laying free in the vitreous body or stopped near the entry wound during injury without other complications. Internal approach - pars plana vitrectomy with forceps removal is used when IOFB is stuck either on the peripheral or posterior part of the retina or if there are some of aforementioned complications.
