目的：评价泪道逆行置管术治疗慢性泪囊炎的有效性、安全性。 方法：选取2009-12/2011-12来本院就诊的慢性泪囊炎患者42例42眼，在局部麻醉下将泪道再通管逆行置入鼻泪管内，术后3~6mo拔管，拔管后随访6mo，观察其有效性及并发症发生情况。 结果：所有42例患者均顺利置入泪道再通管，常规3~6mo拔管。42例患者中40例患者拔管时泪道冲洗通畅。拔管后6mo有效率88%，发生并发症3例。 结论：泪道逆行置管治疗慢性泪囊炎操作简单，适用范围广，有较好的有效性及安全性,值得推广。

AIM:To evaluate the safety, efficacy of retrograde lacrimal intubation for treatment of chronic dacryocystitis. METHODS:This study included 42 cases (42 eyes) with chronic dacryocystitis from December 2009 to December 2011.
