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.
一只2岁的雄性魏玛犬出现急性发作的非轴向眼球突出，左眼眼球背侧移位。左侧眼眶周围肿胀、疼痛，并有大量脓性眼部分泌物。左侧腹侧结膜穹窿部有一个引流窦道，左侧翼腭窝也有一个。全面眼科检查显示右眼正常。眼眶超声检查发现左眼眶腹外侧有大的、双条、线性、平行的回声带并伴有声影，提示有异物。眼后段也有变形。试图在超声引导下通过腹侧结膜穹窿部和翼腭窝的引流窦道取出眼眶异物。两种方法均未成功；然而，取出了少量有机物质，证实了眼眶异物的诊断。磁共振成像（MRI）显示一个8×1.5×0.8厘米的线性异物，从眼眶延伸至口咽部水平。在左侧进行改良外侧眶切开术并切除颧弓后取出了木质异物。
