方法：按月龄分为1～3月龄组、4～6月龄组、7～12月龄组和13～24月龄组，给予泪囊按摩法、泪道冲洗法及泪道探通法，观察各方法在各组的疗效。分析剖宫产是否是新生儿泪囊炎的发病原因。

结果：1～3月龄组与4～6月龄组比较，差异有统计学意义(χ²=19.89，P<0.05)，泪囊按摩法对6mo以下的患儿有效，1～3月龄患儿效果最佳。泪道冲洗法四组疗效比较，差异有统计学意义(χ²=54.95，P<0.05)，其中1～3月龄组与4～6月龄组比较，无统计学差异(χ²=0.00003，P>0.05)，其他各组间比较P值全部<0.05，各组间应用泪道冲洗法疗效皆有差异。7～12月龄组和13～24月龄组比较，差异有统计学意义(χ²=10.29，P<0.05)。剖宫产组占总例数85%。

结论：3月龄以下的患儿泪囊按摩可以取得很好的疗效。泪道冲洗对12月龄以下的小儿疗效确切。泪道探通对于7～12月龄患儿有很好的疗效，而对于12月龄以上的小儿效果欠佳。剖宫产是新生儿泪囊炎的重要原因。

METHODS: A total of 260 cases(260 eyes)of children with neonatal dacryocystitis were divided into 1-3 months group, 4-6 months group, 7-12 months group and 13-24 months group, Each group was respectively given the lacrimal sac massage, lacrimal passage irrigation and probing of lacrimal passage method. Curative effect of each method was observed in different groups. Analysis was made to determine whether caesarean section was the cause of neonatal dacryocystitis.

RESULTS: The comparison between 1-3 months group and 4-6 months group showed significant difference(χ²=19.89, P<0.05). Lacrimal sac massage was effective for babies under 6 months, particularly in 1-3 months babies. The curative effect of lacrimal passage irrigation in four groups was compared, and there was statistical significance in the difference between the curative effect of each group(χ²=54.95, P<0.05). The difference between the 1-3 months group and 4-6 months group was χ²=0.00003, P>0.05, lacrimal passage irrigation of these two groups showed no significant difference in efficacy. The comparison result between the other two groups showed no significant difference(P<0.05), lacrimal passage irrigation effects are different from each group. The comparison result between 7-12 months group and 13-24 months group was χ²=10.29, P<0.05. Infants born by cesarean section accounted for 85% of all cases.

CONCLUSION:Lacrimal sac massage can exert very good therapeutic effects in infants less than 3 months. The curative effects of irrigation of lacrimal passage are quite good in babies under 12 months. Probing of lacrimal passage has a good curative effect in 7-12 months infants, but a poor curative effect in babies over 12 months. Caesarean section is an important cause for neonatal dacryocystitis.
