Wooden orbital foreign body in a Weimaraner.

Abstract

A 2-year-old, male Weimaraner presented with acute-onset nonaxial exophthalmos with dorsal deviation of the left globe. Periorbital swelling, pain and a profuse purulent ocular discharge were present on the left side. A draining sinus tract was present in the left ventral conjunctival fornix and another in the left pterygopalatine fossa. The right eye was normal on complete ophthalmic examination. Orbital ultrasonography revealed large, double, linear, parallel echogenic bands with shadowing present in the ventrolateral aspect of the left orbit suggestive of a foreign body. Deformation of the posterior segment was also present. Removal of the orbital foreign body was attempted under ultrasound guidance via the discharging sinuses in the ventral conjunctival fornix and the pterygopalatine fossa. Neither approach was successful; however, a small amount of organic material was retrieved confirming the diagnosis of orbital foreign body. Magnetic resonance imaging (MRI) revealed a linear foreign body of 8 x 1.5 x 0.8 cm extending from the orbit to the level of the oropharynx. A modified lateral orbitotomy with zygomatic arch resection on the left side allowed removal of the wooden foreign body.
