【摘要】 目的 探讨局部注射丝裂霉素治疗早期翼状胬肉的疗效。方法 选择胬肉组织侵入角膜内2 mm的患者386例464眼,在显微镜下,将0.2 mg/ml的丝裂霉素溶液0.1~0.3 ml注入胬肉头颈体部。术后复方妥布霉素眼液,涂复方妥布霉素眼膏,常规疗程1周。1周后同法治疗。观察角膜浸润、胬肉血管及胬肉组织的肥厚程度。随访不少于6个月。结果 治愈436眼,好转28眼,无效0眼。出现点状角膜炎6例6眼,经治疗均痊愈。结论 局部注射丝裂霉素能有效治疗早期翼状胬肉

[Abstract] Objective To evaluate the efficacy therapeutic effect of regional injection of mitomycin C for treating patients with pterygium.Methods 464 eyes of 386 patients with corneal incursion less than 2 mm were received 0.1~0.3 ml of 0.2 mg/ml mitomycin C locally injected into the head and body of pterygium under microscope.Subsequently,all eyes were treated with tobramycin and dexamethasone ophthalmic suspension (qid) and tobramycin and dexamethasone ophthalmic ointment (qn) for 1 week.And then,the same therapy above—mentioned were repeated again.The corneal infiltration,blood vessels and plump degree of pterygium were observed.The follow—up of 6 months and over were carried out to all of patients.Results After local injection of mitomycin C,the pterygium were resolved in 436 eyes,and improved in 28 eyes.6 eyes of 6 patients were suffered from punctuate keratitis and healed within one month.Conclusion Localized mitomycin C is an effective treatment for pterygium in early phase.

翼状胬肉(以下简称胬肉)是肥厚的结膜和结膜下组织由球结膜向角膜侵袭,是一种常见多发病,胬肉不但给患者带来容貌方面的困惑,同时,病程漫长,局部经常充血发炎,给患者带来许多的不适症状,影响患者的生存质量。胬肉治疗方法较多,目前仍以手术为主,但术后复发率高达20%~50%,因而仍是眼科医师较棘手的问题之一。我们在门诊对早期的胬肉进行局部注射丝裂霉素(0.2 mg/ml)治疗,收到良效,现报告如下。

1 资料与方法。

1.1 一般资料 自2000年1月至2006年6月,我院门诊早期翼状胬肉患者(胬肉组织侵入角膜内小于2 mm)386例464眼,男168例184眼,女218例280眼;年龄最大55岁,最小25岁,平均(38.5±0.21)岁。

1.2 方法 日本株式会社产丝裂霉素注射粉剂2 mg+无菌生理盐水5 ml+2%利多卡因5 ml,置于4 ℃冰箱保存(最长时间不超过1周)备用。患眼用0.5%地卡因表面麻醉后,用1 ml注射器抽取0.5 ml备用的丝裂霉素溶液(0.2 mg/ml),在手术显微镜下,针头从胬肉颈部上方进针,将0.2 mg/ml的丝裂霉素溶液0.1~0.3 ml注入胬肉头颈体部。1周后,同法进行局部治疗术后复方妥布霉素眼膏复方妥布霉素滴眼液点术眼,qid,复方妥布霉素眼膏涂术眼,qn,持续用药1周。出现角膜上皮点状着色者,给予重组人表皮细胞生长因子衍生物滴眼液,重组牛碱性成纤维细胞生长因子眼用凝胶,qn,口服消炎痛25 mg,维生素C片0.2 g,维生素B1片20 mg,tid。

1.3 疗效判定标准 术后观察至少6个月。治愈:角膜无浸润灶,胬肉头苍白萎缩、无血管侵入,胬肉体变薄、血管减少;好转:角膜无浸润灶,胬肉头萎缩、胬肉头体部血管减少;无效:各项指标与治疗前相同。
