方法：单纯泪小点狭窄或闭锁患者42例72眼，按照年龄分成60岁以上及以下两组。局部麻醉下行引线硅胶管植入术，术后给予局部消炎抗感染治疗。术后冲洗泪道1次/wk，共4次，1～3mo后拔管，计算治愈率，并行卡方检验。

结果：所有患者术中均成功植入引线硅胶管。平均观察14mo。治愈59眼(82%)，好转8眼(11%)，无效5眼(7%)。60岁以上组治愈率、有效率均较60岁以下组低。

结论：引线硅胶管植入术治疗单纯泪小点狭窄或闭锁，操作简便、创伤小、效果好、值得临床推广。

METHODS: Forty-two punctum lacrimale obstruction patients(72 eyes)were involved and underwent silicone lacrimal drainage tube spherical under local anesthesia, after the surgery they all pointed antibacterial eye drops. All patients were divided into two subgroups; one were over 60 years old, the other all under 60. Irrigation of lacrimal passage was performed once a week for 4 times, then the drainage tube was removed one or three months later.

RESULTS: All the patients were successfully implanted with silicone lacrimal drainage tubes. No secretion was found by lacrimal passages irrigating during 14 months. 59 eyes(82%)were cured completely, 8 eyes(11%)were improved significantly, 5 eyes(7%)were unchanged. And the treatment success was more obvious in younger group than that in elder group.

CONCLUSION: The treatment for punctum lacrimale obstruction diseases by planting silicone lacrimal drainage tube is a perfect way. It is simple, safe, and timesaving, less bleeding without incision, scar and has high successful rate. So this method is worth being spread widely.
