目的：探讨鼻窥镜下联合泪道激光泪道置管治疗鼻泪管阻塞的临床效果。 方法：2008-05/2010-06对186 例238眼泪道阻塞患者行鼻窥镜下联合泪道激光逆行泪道置管治疗。通过泪液回收及荧光素排泄试验来判断泪管的通畅度。 结果：经随访186 例238眼治愈214眼( 89.9%) ，好转20眼( 8.4%)，无效4眼( 1.7%)，总有效率98.3%。 结论：鼻窥镜下联合泪道激光泪道置管治疗鼻泪管阻塞安全有效，损伤小，术后复发率低，是泪道阻塞性疾病较理想的治疗方法。

AIM:To evaluate the effects of silicone intubation combined with laser by endoscopy for lacrimal duct obstruction. METHODS: Totally 186 patients (238 eyes) with obstruction of lacrimal passage were treated with the above method from May 2008 to June 2010. Tears recovery and fluorescein excretion test were used to determine the lacrimal duct patency. RESULTS: After the mean follow-up for 5.6 months, 214 of the 238 troubled eyes(89.9%) got cured, 20 eyes (84%) turned for better,4 eyes (1.7%) showed no effect. The total effective rate was 98.3%. CONCLUSION:Combination of laser and silicone intubation by endoscopy is a useful, economical and feasible method to treat the obstruction of lacrimal passage.
