泪液引流是将泪液自眼表引流至鼻腔的过程，它的机制是复杂的，不仅需要眼睑的腺体及肌肉系统的协同，也需要泪液分泌系统及引流系统的共同参与才能发挥。数百年来，泪液引流系统的功能及机制一直受到眼科界的关注，提出了许多代表性的观点，取得了较大的进展，对提高泪道系统疾病的诊疗水平具有重要的临床意义。本文综述了泪液引流系统的解剖背景、机制及目前尚待解决的问题及前景。

[Abstract]
Lacrimal drainage is the process of drainage tear from eye surface to nasal cavity and its mechanism is complex. It requires not only the coordination of gland and muscle system of eyelid, but also the joint participation of lacrimal secretion system and drainage system. For hundreds of years, the function and mechanism of lacrimal drainage system has been concerned by ophthalmologists. Many representative viewpoints have been put forward and great progress has been made. It has important clinical significance to improve the diagnosis and treatment of lacrimal passage diseases. This paper reviews the anatomical background, mechanism, problems and prospects of lacrimal drainage system.
