AI Article Synopsis
- An intraocular foreign body (IOFB) can cause mechanical damage, infection, and toxic effects in the eye, with removal strategies including internal (vitrectomy) and external approaches (large electromagnet).
- A case study highlights a 51-year-old man with a normal visual acuity who had a metallic IOFB successfully removed using an electromagnet, while a 30-year-old man with severe complications underwent a more complex vitrectomy to extract his IOFB.
- The conclusion emphasizes that magnet removal is suitable for uncomplicated cases of IOFB, whereas internal techniques are necessary for more complicated situations, such as when the IOFB is attached or associated with other injuries.
Article Abstract
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= 7 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.

Aim: Foreign body ingestion, particularly that of magnets, is a significant issue for children aged 6 months to 3 years due to their prevalence in toys and household items. Most ingested foreign bodies pass naturally, but 10%-20% of such cases require endoscopic removal, and <1% require surgery.

Both rigid plastics and soft hydrogels find ample applications in engineering and medicine but bear their own disadvantages that limit their broader applications. Bonding these mechanically dissimilar materials may resolve these limitations, preserve their advantages, and offer new opportunities as biointerfaces. Here, a robust adhesion strategy is proposed to integrate highly entangled tough hydrogels and diverse plastics with high interfacial adhesion energy and strength.
