The purpose of the study was to determine the success rate of probing for congenital nasolacrimal duct obstruction after 1 year of age.
A record review.
Two hundred fifty-two patients with 303 obstructed nasolacrimal ducts underwent probing and irrigation by the author between 1971 and 1997 while under brief general anesthesia.
Successful outcome of probing was defined as absence of tearing and discharge in the affected eye.
The overall cure rate in all patients was 92%, varying from 88.9% to 96.8% at different age intervals up to and beyond 3 years of age. Chi-square analysis showed no significant change in cure rate with increasing age.
Probing for congenital nasolacrimal duct obstruction beyond 1 year of age is highly successful, and the cure rate does not vary significantly at intervals of increasing age.
本研究旨在确定1岁以后先天性鼻泪管阻塞探通术的成功率。
病历回顾。
1971年至1997年间，作者在短暂全身麻醉下对252例患者的303条阻塞鼻泪管进行了探通和冲洗。
探通成功的结果定义为患眼无流泪和分泌物。
所有患者的总体治愈率为92%，在3岁及3岁以上的不同年龄区间，治愈率从88.9%至96.8%不等。卡方分析显示，治愈率并未随年龄增长而发生显著变化。
1岁以后对先天性鼻泪管阻塞进行探通术成功率很高，且治愈率在年龄增长区间内无显著差异。
