泪道疾病是多发病、常见病,特别是鼻泪道阻塞性疾病,传统治疗多采用泪囊鼻腔吻合术和经泪小点泪道探通术。传统的泪囊鼻腔吻合术治疗鼻泪道阻塞性疾病效果可靠稳定；随着鼻内窥镜的发展,产生了一种完美而创伤小的泪囊鼻腔吻合术。近年来新型泪道器材的出现,泪道支架、激光或高频电在临床上广泛应用；泪道探通联合新型泪道支架及其他辅助治疗疗效肯定。现在国内外少数医院开展了具有创伤更小,不改变原有组织结构的微创术（泪道内窥镜技术）,应用于鼻泪道阻塞性疾病诊治；这种显微技术在鼻泪道阻塞性疾病方面的诊治具有良好的发展前景。

Thelacrimal duct obstruction is a common disease in ophthalmology, especially the nasolacrimal duct obstruction. It can be treated by probing of lacrimal passage and acryocy storhinostromy traditionally, and its curative effect is sure. With the development of endoscopic, a minimal invasion surgery method was born. In recent years, new lacrimal equipment appearance, lacrimal stent, laster or high-frequency electric applied widely in clinic. Lacrimal duct probing new lacrimal stents and other auxiliary curative''s effect are affirmation. Now at home and abroad a few hospitals carried out a minimally invasive surgery technology (lacrimal duct endoscopy) without changing the original structure. It is used in diagnosis and treatment on nasolacrimal duct obstruction. This microscopic technique in nasal lacrimal duct obstruction diseases has good development prospect. 
