Two 4- and 8-month-old prim'Holstein calves were presented for chronic epiphora. Examination of the affected eyes revealed an abnormal duct opening inferonasal to the medial canthus. A diagnosis of congenital lacrimal fistula was made based on conventional and computed tomographic-dacryocystography findings. These revealed an ectopic channel connecting the nasolacrimal duct to the skin opening near the medial canthus. Both of the calves were surgically treated with resection and closure of the ectopic duct and placement of a nasolacrimal stent.
两头4个月和8个月大的荷斯坦杂交小牛因慢性流泪前来就诊。对患眼检查发现内眦鼻下方有异常的泪道开口。根据传统检查和计算机断层扫描泪囊造影结果诊断为先天性泪囊瘘。这些检查显示存在一条异位通道，将鼻泪管与内眦附近的皮肤开口相连。两头小牛均接受了手术治疗，切除并闭合异位泪道，同时放置鼻泪支架。
