目的:比较泪道探通治疗对三个年龄组的先天性鼻泪管阻塞患者的成功率。方法:共180例先天性鼻泪管阻塞患者根据年龄分为3组, I组(4 ~6mo), II组(7 ~12mo)和III组(13 ~24mo),均行泪道探通治疗。症状体征均消失为治疗成功的标准。用卡方检验分析结果。结果:I组治疗成功率为100.0%, II组治疗成功率为88.5%,III组治疗成功率为82.3%,总的治愈率为90.7%。结论:泪道探通治疗的有效性随着年龄的增加降低。在6mo时行泪道探通治疗的孩子成功率最高,能完全消除症状。
OBJECTIVE: To compare the success rate of probing of lacrimal passages in patients with congenital nasolacrimal duct obstruction in three age groups. Methods: A total of 180 patients with congenital nasolacrimal duct obstruction were divided into 3 groups according to their age: group I (4 ~ 6 months), group II (7 ~ 12 months) and group III (13 ~ 24 months) . Symptoms and signs disappeared as the standard of treatment success. Use chi-square test to analyze the result. Results: The success rate of group I was 100.0%, that of group II was 88.5%, that of group III was 82.3%, and the total cure rate was 90.7%. Conclusion: The effectiveness of probing of lacrimal passage decreases with age. In 6mo line probing the treatment of children with the highest rate of success, can completely eliminate the symptoms.
