带角膜缘的自体结膜瓣移植术治疗翼状胬肉的疗效

目的:观察用带角膜缘的自体结膜瓣移植术治疗翼状胬肉的临床效果。方法:翼状胬肉50例56眼,采取显微手术取同侧眼上方带角膜缘的游离结膜瓣进行移植。行翼状胬肉切除联合带角膜缘的自体结膜瓣进行移植,缝合时注意移植片移植床上角膜缘各自准确对位吻合,术后对角膜上皮化及植片生长情况随访观察。结果:术后随访6～12mo,角膜上皮平整光滑,泪膜正常,供区角结膜创面正常愈合,术后角膜透明或仅遗留少许云翳,无新生血管长入,无1例复发。结论:用带角膜缘的自体结膜瓣移植术治疗翼状胬肉,有利于重建角膜缘功能,是一种治疗翼状胬肉安全有效的手术方法。

Clinical observation of transplantation conjunctival flap with limbal autograft in treatment of pterygium

AIM: To observe the clinical effects of pterygium by transplantation of conjunctival flap with limbal autograft.

METHODS:Totally 50 cases(56 eyes)with pterygium were treated by transplantation of conjunctival flap with limbal autograft. The graft was obtained from the above limbal cornea with bulbar conjunctival flap in the same side,special attention was paid for the accurate alignment of the graft and the corneal bed during suturing, and the epithelialization and growth of the graft were observed.

RESULTS:The followed up was 6-12 months,the corneal epithelialium and the tear film were normal,the donor site keratoconjunctival wound healed properly, all eyes were transparent or only left a little corneal nebula. There was no new blood vessel, and no recurrence was found.

CONCLUSION: Transplantation of conjunctival flap with limbal autograft is conducive to rebuild the limbus function. It is an effective and safe surgical method for the treatment of pterygium.
