目的：观察不同阶段分别采用保守治疗和手术治疗对先天性鼻泪管阻塞的治疗效果。方法：对2008-12/2011-10我院确诊的年龄20天龄～2月龄的37例41眼先天性鼻泪管阻塞患儿分阶段进行保守治疗及手术干预。年龄＜6月龄的患儿采用保守泪囊按摩,年龄＞6月龄的患儿保守治疗不愈者实施泪道探通术。结果：全部患儿完成随访,25眼（61.0%）经保守治疗在6月龄前治愈。16眼（39.0%）经保守治疗无效的患儿在6月龄后接受泪道探通,其中14眼一次性探通成功。2眼二次探通成功。结论：先天性鼻泪管阻塞6月龄前可首选保守按摩治疗,6月龄后手术干预可以提高疗效。

AIM:To discuss the clinical effects of congenital nasolacrimal duct obstruction(CNLDO) in different stages with conservative treatment and lacrimal passage probing. METHODS:Thirty-seven infants (41 eyes), aged 20 days to 2 months, diagnosed with CNLDO were followed in the study between 2008 and 2011. Conservative dacryocyst massage was performed on infants ＜6 months. Lacrimal passage probing was performed on infants ＞6 months when conservative treatment had no effect. RESULTS:All infants finished follow-up,25 eyes(61.0%) were cured within six months after birth. The rest of 16 eyes(39.0%) received lacrimal passage probing after six months, of which 14 eyes resolved after the first probing and 2 eyes resolved after the second probing. CONCLUSION:Conservative treatment before 6 months in CNLDO was recommended. After 6 months, lacrimal passage probing could help promote the effect. 
