方法：将87例102眼患儿分成三个不同的年龄段组：第一组：25天龄～3月龄21例26眼； 第二组：>3～7月龄31例36眼； 第三组：>7～24月龄35例40眼。对第一组实行泪囊鼻泪管按摩+滴眼液治疗； 对第二组进行泪道加压冲洗治疗； 对第三组施行鼻泪管探通术治疗。

结果：第一组患儿经泪囊鼻泪管按摩+滴妥布霉素眼液治疗通畅者12眼，治愈率为46.2%； 第二组患儿经泪道加压冲洗治疗通畅者33眼，治愈率为91.7%； 第三组患儿经鼻泪管探通术治疗通畅者36眼，治愈率为90.0%。第二组和第三组效果明显优于第一组(χ²=15.71，P<0.01； χ²=15.27，P<0.01)； 第二组和第三组治疗效果无明显差异(χ²=0.02，P>0.05)。

结论：婴幼儿先天性鼻泪管阻塞应该区分年龄阶段，采取不同的治疗方法，才能获得较好的治疗效果，而泪道加压冲洗是治疗婴幼儿先天性鼻泪管阻塞的首选方式。

METHODS:The 87 cases of 102 children were divided into three different age groups: the first group of 25d-3mo of age 21 cases 26 eyes; The second group >3mo-7mo 31 cases 36 eyes; The third group >7-24mo of age 35 cases 40 eyes. For the first group of infants, the implementation of the lacrimal sac nasolacrimal duct massage + eye drops; for the second group of infants, carry lacrimal pressure washing treatment; for the third group of infants, the implementation of the nasolacrimal duct probing treatment.

RESULTS:The first group of children through the nasolacrimal duct sac massage + drops tobramycin eye drops treatment unobstructed 12, the cure rate was 46.2%; The second group of children through pressurized irrigation treatment lacrimal patency by 33, the cure rate was 91.7%; The third group of children through the nasolacrimal duct probing unobstructed 36 treatment, the cure rate was 90.0%. The second and third group were better than the first group(χ²=15.71, P<0.01; χ²=15.27, P<0.01); the treatment effect of the second and third groups was no significant difference(χ²=0.02, P>0.05).

CONCLUSION:Infants with congenital nasolacrimal duct obstruction should distinguish between ages, taking different treatments, in order to obtain a better therapeutic effect, and lacrimal pressure washing is the preferred way of treating infants with congenital nasolacrimal duct obstruction.
