Epiphora (tearing) is the main symptom of a dysfunction of the lacrimal drainage. Tearing is a common problem and the cause can not easily be identified. Since development and miniaturisation of gastroduodenal endoscopes in the 1990s, it is possible to check the anatomical structure and the pathological changes of the lacrimal drainage system, which has a diameter of 1 mm. Mechanical stenosis is often caused by recurring chronic inflammation. Complete stenosis is usually only punctual and seldom over a long distance. Shortly after the development of microendoscopic diagnostic tools, therapeutic techniques using a laser for the dacryoplasty (LDP) or a microdrill for the dacryoplasty (MDP) were established. For the first time, these treatments enable preservation of the whole physiology of the lacrimal drainage system in spite of surgical intervention.
溢泪是泪液引流功能障碍的主要症状。流泪是一个常见问题，其病因不易确定。自20世纪90年代胃十二指肠内窥镜得到发展并小型化以来，就能够检查直径为1毫米的泪液引流系统的解剖结构和病理变化。机械性狭窄通常由反复发作的慢性炎症引起。完全性狭窄通常仅为点状，很少累及较长距离。在微型内窥镜诊断工具出现后不久，就建立了使用激光进行泪道成形术（LDP）或微型钻头进行泪道成形术（MDP）的治疗技术。这些治疗首次能够在进行手术干预的情况下保留泪液引流系统的整个生理功能。
