To determine the success of probing for congenital nasolacrimal duct obstruction in children aged under 10 years.
A retrospective study.
The medical records of all children aged under 10 years diagnosed with congenital nasolacrimal duct obstruction between 1997 and 2007 who underwent probing and irrigation under general anesthesia were reviewed. Successful probing was defined as absence of tearing and eye discharge in the affected eye at one month or more after treatment. Data obtained included age at first visit, gender laterality of the eyes, history of previous probing, age at probing time, number of probing, and treatment outcomes. Patients were categorized into four groups according to age at treatment (0-1 year, 1-2 years, 2-3 years and 3-10 years).
Forty-four patients were seen during the study period, 19 males and 25females, with 29 right eyes and 30 left eyes undergoing treatments of 29 unilateral probing and 15 bilateral probing. The age at probing ranged from 10 months to 9.6 years (mean +/- SD, 2.51 +/- 1.82 years). Successful probing were identified in 47 out of 59 eyes (80%, 95% CI = 67 to 89%). Most successful eyes required only one probing and only two eyes needed a second probing. The success rates were 80% (8/10 eyes) in patients 0-1 year of age, 86% (18/21 eyes) in patients 1-2 years of age, 75% (12/16 eyes) in patients 2-3 years of age, and 75% (9/12 eyes) in patients 3-10 years of age.
The success rate of probing for treatment of congenital nasolacrimal duct obstruction varies, depending on the age of the child at treatment. It was higher in children under 2 years than in older children.
确定对10岁以下儿童先天性鼻泪管阻塞进行探通术的成功率。
一项回顾性研究。
回顾了1997年至2007年间所有10岁以下被诊断为先天性鼻泪管阻塞且在全身麻醉下接受探通和冲洗的儿童的病历。成功的探通术定义为治疗后一个月或更长时间患眼无流泪和眼分泌物。获得的数据包括初诊年龄、性别、患眼侧别、既往探通史、探通时年龄、探通次数和治疗结果。根据治疗时的年龄将患者分为四组（0 - 1岁、1 - 2岁、2 - 3岁和3 - 10岁）。
研究期间共诊治44例患者，男19例，女25例，29只右眼和30只左眼接受治疗，其中29例为单侧探通，15例为双侧探通。探通时年龄范围为10个月至9.6岁（均值±标准差，2.51±1.82岁）。59只眼中47只探通成功（80%，95%可信区间为67%至89%）。大多数成功的眼睛只需一次探通，只有两只眼睛需要第二次探通。0 - 1岁患者的成功率为80%（8/10只眼），1 - 2岁患者为86%（18/21只眼），2 - 3岁患者为75%（12/16只眼），3 - 10岁患者为75%（9/12只眼）。
先天性鼻泪管阻塞探通术的成功率因治疗时儿童的年龄而异。2岁以下儿童的成功率高于年龄较大的儿童。
