✦ Synopsis

MAGNETIC RESONANCE (MR) IMAGING is contraindicated in patients with certain ferromagnetic implants, devices, and materials, primarily because of the hazards associated with movement or dislodgment (1). This is particularly true for metallic implants located in sensitive areas of the body, such as in or near the eye. Therefore, we tested seven different metallic clips used for scleral buckling for the preserice of ferromagnetic qualities. Scleral buckling is used to treat retinal detachment, whereby the metallic clip secures the two ends of a silicone band that is placed to provide apposition of the sclera and detached parts of the retina (2). This permits healing of a retinal tear without surgical entry into the globe (2). The following seven metallic clips were tested: single tantalum clip, double tantalum clip, and double tantalum clip, style 250 (Storz Instruments,
