方法：选取2015-07-01/2016-06-30我院泪道阻塞婴幼儿患者86例116眼，随机分为观察组43例60眼，对照组43例56眼，观察组采用泪道球囊扩张术，对照组采用鼻泪管探通术。随访6mo，进行疗效比较。

结果：术后6mo时，观察组患者一次治愈率和总治愈率均明显高于对照组(P<0.05)。

结论：球囊扩张术操作安全，临床疗效优于泪道探通，是治疗婴幼儿泪道阻塞的有效方法。

METHODS: Totally 86 patients(116 eyes)with lacrimal duct obstruction from July 1, 2015 to June 30, 2016 were randomly divided into two groups according to the digital table. The observation group(43 cases, 60 eyes)were operated with balloon dilatation and the control group(43 cases, 56 eyes)were treated with duct exploratory operation. The patients were followed up for 6mo to compare the efficacy.

RESULTS: At the 6mo postoperatively, the primary cure rate and total cure rate in the observation group were significantly higher than those in the control group. There was significant difference between the two groups(P<0.05).

CONCLUSION: Balloon dilatation operation is safe, and its clinical efficacy is better than lacrimal duct exploratory operation, is an effective way to treat lacrimal duct obstruction in infants.
