Magnetic resonance imaging and intraocular foreign bodies.
We conducted in vitro and in vivo experiments to study magnetic resonance imaging of intraocular foreign bodies. Diamagnetic and paramagnetic foreign bodies were imaged without artifact and without movement during the imaging process, while ferromagnetic foreign bodies produced large amounts of artifact that prevented meaningful images. All fetromagnetic foreign bodies moved during in vitro ima...
متن کاملRetained intraocular foreign bodies and visual prognosis.
FOREIGN bodies lodged in the eye following perforating injuries are serious ophthalmic emergencies. The retention of a foreign particle within the eye-ball may result in infection, sympathetic ophthalmitis, local irritative and chemical reaction apart from the mechanical damage caused at the time of the accident. The visual prognosis is extremely variable because of so many factors such as exte...
متن کاملImaging Considerations in Suspected Intraocular Foreign Bodies
The mechanisms of trauma resulting in IOFBs vary greatly and play a critical role in establishing the material responsible for injury. The most common place of injury is the workplace [6] and IOFBs ultimately result in 3.3% of all occupational injuries causing lost workdays [7]. Injury most commonly results from hammering (60-80% of IOFBs), but use of power tools and firearms also constitute co...
متن کاملA decade of intraocular foreign bodies.
This communication is based on a retrospective survey of 245 intraocular foreign bodies (IOFB) seen at the Birmingham and Midland Eye Hospital between I96I and I970 inclusive. Because the numbers have been swollen by patients referred from other regions after failed extraction, the results are not strictly comparable with those of other authors, as there tends to be a higher rate of complicatio...
متن کاملCT evaluation of plastic intraocular foreign bodies.
The high sensitivity of CT in detecting metallic orbital foreign bodies has been previously described [1-6] . While there has been some success in detecting glass fragments , detecting intraorbital foreign bodies made of wood has been very unsatisfactory [1, 2, 69]. Plastic orbital implants are easily recognized on CT as high-attenuation-value images [6, 7]. This report presents two cases of pl...
