目的：探讨探通术的成功率与鼻泪管阻塞(nasolacrimal duct obstruction， NLDO)患者年龄之间的相关性。
方法：患者120例行探通术，并分为3个年龄组：第1组(<12mo)，第2组(13～24mo)，3组(25～60mo)。所有患者先行保守治疗，阻塞未消除，然后行探通术作为替代治疗，并比较三组间的探通术治愈率。
结果：组1，2，3的成功率分别为94.3%， 83.3%， 68.4%。三组间的治愈率有显著的差异(P=0.017)。
结论：早期行探通术可取的较高的成功率。根据我们的观察， NLDO患者早期干预，最好在出生后2a以内，效果肯定。

[Abstract]
AIM:To determine the correlation between success rate of probing and age in patients with nasolacrimal duct obstruction(NLDO).
METHODS: A total of 120 patients who underwent probing were studied. Patients were divided into three age categories: group 1(younger than 12 months), group 2(between 13 to 24 months), and group 3(between 25 to 60 months old). At first conservative management was initiated for all patients, but the obstruction didn't resolve so probing was performed as an alternative treatment. The cure rate of probing was compared between the three categories.
RESULTS: The success rate in groups 1 to 3 was 94.3%, 83.3%, and 68.4% respectively. Cure rate of probing differed significantly between the three groups(P=0.017).
CONCLUSION: Probing is associated with a higher success rate if performed early in life. Based on our observation, early intervention for NLDO, preferably in the first two years, is warranted.
