Objective To compare the efficacy of different mitomycin C (MMC) concentration injection in recurrent obstruction after dacryocystorhinostomy.Methods A randomized controlled clinical study,74 eyes (72 patients) of recurrent obstruction after endoscopic dacryocystorhinostomy because of simple chronic dacryocystitis were divided into study group and control group from February 2010 to January 2013.The study group was divided into 3 sub-groups according to different MMC concentration,18 eyes applied by 0.2mg/ml MMC,19 eyes applied by 0.5mg/ml MMC,19eyes applied by 1.0mg/ml MMC.MMC was used at the hole for 5 minutes after the obstruction had been knocked through by laser.Lacrimal drainage tube was placed in the hole for 1 month.Eighteen eyes were enrolled in the control group and did not use MMC before placing the lacrimal drainage tube.The observation and statistical analysis include Epiphora,granulation tissue,the height of lacrimal river and patency of lacrimal.Results The anastomotic formed in 14 eyes in 0.2mg/ml MMC group and 17 eyes in 0.5mg/ml MMC group and 19 eyes in 1.0mg/ml MMC group.There was statistical difference between 0.2mg/ml MMC group and 1.0mg/ml MMC group.The granulation tissue and formation of membrane at the anastomotic decreased gradually with time.In control group,symptom of epiphora disappeared in 4 eyes,and 2 eyes relieved,but 3 eyes had no change.There was statistical difference between study group and control group.Conclusions MMC has significantly inhibitory action on proliferation of granulation tissue and fibrous tissue as an antimetabolite drug.The decrease of granulation tissue and formation of membrane at the anastomotic are related with the increase concentration of MMC.

目的 探讨泪小管炎的误诊原因,以提高诊疗水平.方法 回顾分析我院泪道科收治的6例泪小管炎误诊病例的临床资料.结果 本组6例占我院同期诊治泪小管炎的60％(6/10),4例误诊为慢性泪囊炎,2例误诊为急性结膜炎,误诊时间10d～3个月.后经相关检查确诊为单纯性上泪小管炎3例,上下泪小管炎2例,下泪小管炎1例,均予相应治疗.经治疗7～18d后全部治愈.结论 上、下端泪小点同时冲洗一端不通畅并有脓液溢出、泪小管周围红肿时应高度警惕泪小管炎,并要根据不同情况酌情采取切开、冲洗、搔刮等方法治疗.

回顾分析33例(39只眼)单纯行白内障超声乳化联合人工晶状体植入术治疗闭角型青光眼的临床资料.结果 术后眼压为(15.11±3.18) mmHg,明显低于术前眼压,前房明显加深,房角情况不同程度改善.术后矫正视力显著提高,并发症很少.认为单纯白内障超声乳化联合人工晶状体植入术是闭角型青光眼安全有效的治疗方法 .

脉络膜上腔出血是指内眼手术中或术后出现的不明原因脉络膜下出血,为内眼手术最严重的并发症之一,若诊治不当,可致患者视力完全丧失.我院收治2例脉络膜上腔出血,现报告如下.
