A 1.5-year-old MC Cardigan Welsh Corgi was presented for a right oral fistula associated with left tonsil enlargement that responded to medical treatment. A first computed tomography scan was performed and showed no signs of a foreign body. Medical treatment was continued for 2 additional weeks and the dog was free of clinical signs for 3 months. The dog was presented again for a 3-day history of anorexia and marked pain when opening the jaw. The repeat computed tomography scan revealed a migrating foreign body near the optic canal of the right eye, and surgical exploration confirmed that it was trapped within the intraconal part of the retrobulbar space, abutting the optic nerve. The foreign body was surgically removed through an osteotomy of the zygomatic bone. The dog fully recovered with no vision loss. Based on the literature search, this is the first published report describing a migrating grass awn located in the intraconal part of the retrobulbar space, abutting the optic nerve.
一只 1.5 岁的 MC 卡迪根威尔士柯基犬因右侧口腔瘘管伴左侧扁桃体肿大就诊，该瘘管对药物治疗有反应。进行了首次计算机断层扫描 (CT) 检查，未见异物迹象。继续药物治疗 2 周后，犬 3 个月内无临床症状。该犬因 3 天厌食和张口时明显疼痛再次就诊。重复 CT 扫描显示右眼视神经管附近有一个移行异物，手术探查证实它被困在眼球后眶内间隙的眶内部分，紧贴视神经。异物通过颧骨切开术取出。犬完全恢复，无视力丧失。根据文献检索，这是第一份描述移行草刺位于眼球后眶内间隙眶内部分、紧贴视神经的报告。
