绵羊（ovis aries）泪道系统的解剖学和影像学研究。

Am J Vet Res. 1979 Aug;40(8):1177-9.

The lacrimal drainage system of the sheep (Ovis aries) was studied, using radiographic and anatomic techniques. The straight course of the nasolacrimal duct and the adequate diameter of different parts of the system facilitates radiography and catheterization of the lacrimal drainage system.

采用放射学和解剖学技术对绵羊（Ovis aries）的泪液引流系统进行了研究。鼻泪管走行笔直，且该系统不同部位直径适宜，便于对泪液引流系统进行放射学检查和导管插入操作。
