[A case of penetration into the eye and orbit of a giant foreign body (a coil spring)].

Descriptions of penetration of large foreign bodies into the orbit are rare. The authors describe a patient who got a coil spring, 40 cm x 2.5 mm in size, in the orbit, when collecting metal scrap; the spring slipped off and penetrated into the orbit. Before examination the exterior part of the spring at the orbital edge was cut off with cutting pliers. Ultrasonic scanning was used before and during surgery, that permitted visual monitoring of the operation and helped prevent possible complications when removing the fragment, thus helping a successful outcome of surgery.
