title: Ferrous intraocular foreign bodies and magnetic resonance imaging.
abstract: We placed various sized ferrous foreign bodies in and around the eye, sclera, and orbit in a rabbit model before performing magnetic resonance imaging studies. All foreign bodies were detected on plain x-rays. Only one of the largest fragments (3 x 1 x 1 mm) demonstrated movement on exposure to the magnetic field.
