目的:了解翼状胬肉手术采用逆行撕剥方法对术后角膜上皮修复时间和远期预后的影响。方法:对56眼原发性翼状胬肉患者随机分成2组,常规剥离组采用从头部到体部的常规剥离方式,逆向剥离组采用从体部到头部的逆向剥离方式,2组均同时联合带蒂结膜瓣转移,术中均使用丝裂霉素棉片浸润巩膜暴露区,术后观察角膜上皮修复时间和远期愈合情况。结果:逆向剥离组比常规剥离组角膜上皮完成修复时间明显提前(t=4.79,P<0.05),逆向剥离组复发率(1.6%)明显低于常规剥离组(10.2%,χ2=4.06,P<0.05)。结论:翼状胬肉手术采用逆向剥离方式可以实现加快角膜上皮修复、减少术后复发的目的。

AIM:To study the effect of corneal epithelium healing time and long-term prognosis on pterygium by the surgery with reverse stripping.METHODS:To divide 56 eyes with primary pterygium into 2 groups randomly.The cases of reverse stripping group were treated by tearing the pterygium from the body to the head.The cases of conventional stripping group were treated by tearing the pterygium from the head to the body.All cases were treated by transplanting the pedicle-conjunctival flap and soaking the exposed sclera with MMC tampon during the operations.To observe the healing time of corneal epithelium and long-term prognosis.RESULTS:The reverse stripping group showed the shorter repair time of corneal epithelium(t=4.79,P<0.05)and the recurrence rate of reverse stripping group(1.6%) is significantly lower than that of conventional stripping group(10.2%,χ2=4.06,P<0.05).CONCLUSION:Pterygium treated by reverse stripping can promote the repair of corneal epithelium and reduce the postoperative recurrence.
