随着治疗方法的进展,角膜溃疡穿孔已极少见,但仍为一种严重并发症。以往常用烧灼术及结膜瓣遮盖术治疗角膜瘘,但效果都不够满意,若溃疡位于角膜中央,手术后不可能保留有用视力,瘘管的封闭也往往不能持久,若在结膜瓣遮盖术后再做角膜移植术,移植片能保持透明的可能性也小。 With advances in treatment, perforation of corneal ulcers has been rare, but is still a serious complication. In the past often used cautery and conjunctival flap cover surgery for corneal fistula, but the results are not satisfactory, if the ulcer is located in the cornea, after surgery can not retain useful vision, fistula closed often can not be sustained, if the conjunctival flap cover after surgery Corneal transplantation, the possibility of graft transparency is also small.
