Intraocular foreign body (IOFB)
- IOFBS may be in the anterior chamber, iris, lens or vitreous; on the retina or even behind the eyeball after doubly perforating the eye
- Corneal abrasion
- Perforation of the eye
- Retinal toxicity from a metallic IOFB
- Radiograph of the orbit with a localizing ring
- Removal of subtarsal, conjunctival or corneal foreign body under magnification e.g. slit lamp microscope
- Ultrasound should be avoided in an eye with a perforating wound
- Appropriate protective goggles for sports, welding, game hunting etc
