目的 观察 2 46例 ( 315只眼 )可疑先天性泪道阻塞并行泪道冲洗及探通术的病例 ,对方法及疗效作一探讨。方法 对可疑患儿行泪道冲洗及探通术。患眼局部麻醉后 ,清洗消毒 ,泪点扩张器扩张泪小点并冲洗泪道。之后 ,以探针从泪小点进针 ,沿泪道走行直达下鼻道。 1周后复诊 ,必要时重复治疗。结果 315只眼中 ,2 88只眼( 91.4% )为泪道阻塞 (泪道阻塞合并泪囊炎 174只眼 ,泪道阻塞 97只眼 ,单纯泪小点膜闭 17只眼 ) ,泪道狭窄 2 7只眼 ( 8.6 % )。治愈 30 6只眼 ,治愈率 97.1%。结论 泪道冲洗及探通术对先天性泪道阻塞有切实疗效 ,且在临床上简便易行。
Objective To observe the cases of suspected lacrimal duct obstruction and lacrimal duct flushing in 246 cases (315 eyes), and discuss the methods and curative effects. Methods To carry out lacrimal irrigation and exploration of suspicious children.
