Intracapsular Extraction of Intralenticular Magnetic Foreign Bodies.
INTRALENTICULAR magnetic foreign bodies if left untreated lead in most instances to total cataract formation, siderosis, or as a later complication, loss of the eye. Since the use of the magnet has been developed, and powerful hand instruments have made manipulation easier, intralenticular magnetic foreign bodies have been removed by this means via the anterior route. The risk of siderosis is t...

manner in which cocain can be used as a test for paralysis of the sympathetic nerve, as a valuable quality. Information with regard to other drugs in this respect would be valuable. It has been suggested to me that the stimulating action on the sympathetic nerve might prove to be a test of the power of a drug to act as a stimulant of the central nervous system, and that so it might beconme a te...
متن کاملMagnetic 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 کاملUpper aerodigestive magnetic foreign bodies in children.
OBJECTIVES/HYPOTHESIS Small, powerful magnets are increasingly available in toys and other products, and are responsible for increasing numbers of foreign body injuries in children. Small, spherical, neodymium magnets available since 2008 are of particular concern. We aimed to identify all cases of upper aerodigestive foreign bodies at our institution over 15.5 years of study. STUDY DESIGN Ca...
متن کاملVisual outcome and prognostic factors after magnetic extraction of posterior segment foreign bodies in 40 cases.
AIMS To evaluate the clinical features as well as the visual and anatomical outcome in eyes with magnetic posterior segment foreign bodies, to identify prognostic factors after removal using an electromagnet. METHODS The records of 40 patients with posterior segment foreign bodies were retrospectively reviewed for 6 years (1989-94). Post-traumatic cataracts and secondary retinal detachments w...
