Microsurgical Treatment of Mooren‘s Ulcer

Objective:To evaluate effect of lamellar keratoplasty(LKP) on Mooren's corneal ulcer.Methods:The effect ,postoperative astigmatism,postoperative vision,ulcer recurrence of postperation,and surgical complications of two groups of consecutive Mooren's ulcer inpatients treated respectively by non-microsurgery of LKP and microsurgery of LKP were analyzed.Results:There were significant differences of the effect,postoperative astigmatism,postoperative vision,ulcer recurrence of postoperation,and surgical complications be-tween the two groups.The effect and postoperative vision of the microsurgery-tyeated group were betterthan those of the non-microsurgery-treated group.The postoperative astigma-tism,ulcer recurrence of postoperation, and surgical complications of the micro-surgery-treated group were less than those of the nonmicrosurgery-treated group.Conclusion:Microsrugery of LKP of Mooren's corneal ulcer can greatly improve the ul-cer healing and postoperative vision, and reduce the surgical complication and the ulcer recurrence of postoperation.Eye Science 2000;16:56-60.

试题与答案

1．以下有关恶性Mooren溃疡的临床特点描述不正确的是：

双眼蚕蚀性角膜溃疡伴翼状胬肉一例

蚕蚀性角膜溃疡又称Mooren溃疡，是一种自角膜缘开始的渐进性、伴有疼痛的周边性角膜溃疡。翼状胬肉是局部球结膜纤维血管组织呈三角形增生而侵入角膜的一种眼科常见疾病。然而两种疾病同时发生的病例非常罕见，目前仅在国外有两例报告，我国还未见报道。

角膜基质透镜用于周边板层角膜移植术的临床效果

目的探讨冰冻保存的角膜基质透镜作为角膜移植材料应用于周边板层角膜移植术的临床效果。方法对Terrien边缘角膜变性3例及Mooren角膜溃疡2例，以角膜基质透镜为植片进行周边板层角膜移植术。基质透镜来自飞秒激光小切口基质透镜取出术（SMILE）。术后随访6个月，观察视力、植片情况及并发症。结果术后角膜基质透镜植片与植床均贴合良好，无植片浑浊、层间积血积液、植片移位、继发感染或植片排斥反应等并发症发生。结论在角膜供体缺乏的情况下，以角膜基质透镜作为周边板层角膜移植材料安全有效。
