我科采用泪道逆行插管涂油方法,治疗泪道阻塞40例47只眼,现小结如下。一、病例选择及操作方法:有泪小点、泪小管狭窄,鼻泪管阻塞以及慢性泪囊炎者。插管前先行泪道探通,在下鼻道中端看到探针头部者,才可进行插管。慢性泪囊炎患者,须先用抗生素溶液作泪道冲洗治疗一周。器械需用额镜、鼻镜、枪状镊、眼科泪道冲洗用具一套、鼻泪管(Bowman)探针0～2一端用微砂轮磨成沟状缺口,自制穿有1号丝线的空心塑料管一条(长约90～100mm,一端外径1.5mm,另一端为0.2～0.3mm)。插管方法:先用1％地卡因棉片放在患眼 I use lacrimal duct retrograde intubation method, the treatment of lacrimal duct obstruction in 47 cases of 47 eyes, are summarized as follows. First, the case selection and operation method: a tear dot, small canalicular stenosis, nasolacrimal duct obstruction and chronic dacryocystitis. Before intubation lacrimal duct probing, in the lower end of the nose to see the probe head, can be intubated. Chronic dacryocystitis patients, must first use antibiotic solution for lacrimal duct irrigation treatment for a week. Instruments need to use the forehead, nose, gun tweezers, ophthalmology lacrimal irrigation a set of equipment, nasal lacrimal duct (Bowman) probe 0 ~ 2 one end of grinding with a micro-grinding wheel into a groove-shaped gap, A plastic pipe (about 90 ~ 100mm, one end of the outer diameter of 1.5mm, the other end of 0.2 ~ 0.3mm). Methods of intubation: first with 1% of cotton on the affected eyes
