原发性获得性鼻泪管阻塞(primary acquired nasolacrimal duct obstruction，PANDO)是泪道阻塞性疾病中最常见的一类，好发于中老年女性，是眼科临床上的常见病、多发病，常继发急性或慢性泪囊炎的症状和体征，严重影响患者的日常工作和生活。本文对近年来PANDO可能的发病机制相关的研究进展、亟待解决的问题及未来研究的热点方向作一综述，旨在进一步加深对泪道阻塞性疾病发生发展的认识。

Primary acquired nasolacrimal duct obstruction (PANDO), which mainly occurs in the middle-aged and elderly women, is the most common type of obstructive diseases of the lacrimal duct, and it is also a common and frequently-occurring disease in ophthalmology. It constantly occurs secondary to various symptoms and signs of acute or chronic dacryocystitis, which seriously affects the daily work and life of patients. This article summarizes the research progress on the possible pathogenesis of PANDO in recent years, the urgent problems to be solved

and the hot research directions in the future, aiming to further deepen the understanding of the occurrence and development of lacrimal obstructive diseases.

目的：探讨先天性鼻泪管阻塞的临床治疗效果。方法：选取在咸阳彩虹医院接受治疗并有随诊记录的先天性鼻泪管阻塞患儿共630例(827眼)。根据年龄大小，采用4种方式统计治疗效果。结果：年龄0~2个月患儿230例(286眼)，选取泪囊按摩和局部点抗炎眼水治疗，182眼(63.63%)治愈；2~6个月患儿240例(340眼)，选取加压冲洗或泪道探通术治疗，338眼(96.74%)治愈；6~12个月患儿150例(188眼)，选取泪道冲洗+泪道探通术治疗，188眼(89.74%)治愈；1岁以上患儿10例(13眼)，选取泪道探通术加局部抗炎治疗，10眼(76.92%)治愈。结论：2~6个月是先天性鼻泪管阻塞治疗的最佳时间，泪道冲洗加探通技术在治疗婴幼儿先天性鼻泪管阻塞创伤小，疗效肯定，远期复发率低。

Objective: To discuss the therapeutic effects of congenital nasolacrimal duct obstruction. Methods: A total of 630 children (827 eyes) with congenital nasolacrimal duct obstruction who were treated in Xianyang Rainbow Hospital and had follow-up records were selected. According to the age, the therapeutic effects were carried out in four ways. Results: A total of 230 cases (286 eyes) aged 0–2 months were treated by massaging lacrimal sac withantiinflammatory eye water, 182 eyes (63.63%) were healed; 240 cases (340 eyes) aged 2–6 months were treated by pressor clysis and lacrimal passages probing, and among them 338 eyes (96.74%) were healed. 150 cases (188 eyes) aged 6–12 months were treated with lacrimal passage irrigation and lacrimal passage probing. 188 eyes (89.74%) were cured; 10 cases (13 eyes) aged over 1 year old were tread by probing of the lacrimal passages with anti-inflammatory eye water, 10 eyes (76.92%) were healed. Conclusion: 2 to 6 months is the best time for the treatment of congenital nasolacrimal duct obstruction, the therapy of pressor clysis with lacrimal passages probing chosen according to the age can treat the congenital nasolacrimal duct obstruction efficiently and decrease the long-term recurrence
