目的探究泪小管炎的诊断和病因，采取有效的治疗方法。方法选取2014年1月~2015年2月收治的33例泪小管炎患者，对泪小管的分泌物给予细菌和真菌的培养，同时采取针对性治疗，严重者还要进行泪小管的切开、挤压和冲洗，观察患者的治疗效果。结果在检查中泪小管管壁有肿胀增厚的症状，回声减弱，和周围组织没有清晰界限，管腔有明显的扩张，而且管径有明显增宽，内径在：3.4 mm×2.6 mm~5.6 mm×4.0 mm。3个月后进行复查，发现原病变区的泪小管管壁为均匀的高回声，和周围组织有明显分界，管腔有轻度的扩张或者恢复正常，内径为：0.3 mm×0.6 mm~0.6 mm×1.0 mm，有统计学意义(<0.05)。结论真菌为造成泪小管炎主要的致病菌，采用泪小管切开、挤压和冲洗结合的治疗，以及敏感抗生素和抗真菌药物的使用，能够提高治疗效果。“,”Objective To explore the lacrimal duct inflammation diagnosis and cause,ef ective treatment methods.Methods January 2014~February 2015 were treated 33 cases of lacrimal duct inflammation in patients,to give canalicular secretions culture of bacteria and fungi,while taking specific treatment,but also for serious cut canaliculus,squeezing and rinsing,observe patient outcomes. Results During the inspection canalicular wal thickening swel ing symptoms,echo weakened,and there is no clear boundary surrounding tissue,a significant expansion of the lumen,but also significantly widened diameter,inside diameter:3.4mmí2.6mm~5.6 mmí4.0mm.For review three months later,was found canalicular wal of the original lesion is homogeneous hyperechoic,and surrounding tissue sharply demarcated,bore:0.3mmí0.6mm~0.6mmí1.0mm,a significant ef ect was statistical y significant ( <0.05).Conclusion The fungus is caused by inflammation of the lacrimal duct major pathogen, using canalicular cut,squeeze and rinse combination therapy,and the use of sensitive antibiotics and antifungal agents,can improve treatment.
