植入性虹膜囊肿与角巩膜创伤修复

The relation of epithelial downgrowth cyst of iris and wound repair of cornea and sclera.

目的 探讨防止虹膜囊肿形成的可靠方法。方法 应用显微镜的高分辨力行角巩膜创伤口修复术 ,彻底清除脱出虹膜表面膜状物及创缘部的破碎上皮。术后随访 1～ 8年 ,并与直视下创口修复者随访情况对比。结果 发病率由原来住院的 0 2 5 % ,下降到 0 0 6 %。结论 显微镜下角巩膜创口修复术 ,可有效降低虹膜囊肿的发病率 ,并改变虹膜脱出超过 12小时不宜还纳的传统观念。

To discuss how to prevent the formation of epithelial downgrowth cyst of iris. Methods To repair the cornea or sclera wound under microscope with high resolution and removed the abnormal prolapsing membraniform substance and crashed epithelium at the edge of wound. Results The incidence rate decreased from 0.24% to 0.06% of impatients. Conclusions Wound repair of cornea and sclera under microscope could reduce the incidence of rate of implantation cyst of iris effectively and changed the traditional opinion that the iris prolapsed over 12 hours wasn't suitable for restoration.
