目的:手术显微镜下翼状胬肉切除联合丝裂霉素C应用疗效观察。方法:采用在手术显微镜下操作:局部麻醉后用角膜剪在角膜缘外1mm处轻轻剪开浅层结膜,分离结膜与胬肉组织,剪除胬肉及肥厚增生的结膜下组织,在手术显微镜下把残留在角膜和巩膜上的胬肉组织彻底清除,并用0.2g/L丝裂霉素溶液棉片置于术区巩膜表面3min,间断缝合把结膜瓣固定在浅层巩膜上,暴露角膜缘后巩膜3～4mm,术后滴用复方硫酸新霉素眼药水,4次/d,连用2wk。结果:所有病例门诊随访,时间3～48mo,手术后角膜刺激症状持续天数减少,术后视力有提高者40眼(39.2%),复发4眼(3.9%)。结论:手术显微镜下行翼状胬肉切除,辅助应用0.2g/L丝裂霉素,复发率低,反应轻。

AIM:To observe the efficacy of pterygium microsurgery and mitomycin C in pterygium patients.METHODS:All the operation procedure was under the operating microscope:after local anesthesia,conjunctiva was cut outside the 1mm of limbus with corneal scissors,conjunctival and pterygium tissue were isolated,and the proliferation of pterygium was cut off,hypertrophy conjunctival tissue,and residual pterygium in the cornea and sclera were cleared off.After that,cotton pad with 0.2g/L mitomycin C solution was placed on the surface of the sclera ablation area for 3 minutes,fixed conjunctival flap was sutured to the sclera and the cornea,limbus and sclera was exposed (3-4mm).After that,the eyes drops of compound neomycin sulfate was used q.i.d.for 2 weeks.RESULTS:The follow-up was 3-48 months,the number of continual days of corneal irritation after surgery was reduced in all out-patients.The visual acuity was improved in 39.2% of patients and the recurrence rate was 3.9%.CONCLUSION:Pterygium microsurgery and 0.2g/L mitomycin C application is a method of low recurrence rate and mild reaction.
