PURPOSE
we report a case of late spontaneous large detachment of Descemet's membrane in recurrent pellucid marginal degeneration after penetrating keratoplasty.
OBSERVATIONS
a 73-year-old man presented to clinic with spontaneous detachment of his Descemet's membrane 30 years after penetrating keratoplasty for pellucid marginal degeneration. Efforts were made to bubble the membrane back into place without success. The patient then underwent endothelial keratoplasty with successful restoration of cornea clarity.
CONCLUSIONS AND IMPORTANCE
this condition may cause diagnostic and treatment dilemmas if not properly identified and managed. In addition this case has information for both the use of scleral contact lens and the success of endothelial keratoplasty in an extremely steep cornea.
目的
我们报告一例穿透性角膜移植术后复发性透明边缘变性患者发生Descemet膜迟发性自发大剥离的病例。
观察结果
一名73岁男性因透明边缘变性接受穿透性角膜移植术后30年，出现Descemet膜自发剥离。曾尝试将膜吹泡复位但未成功。随后该患者接受了内皮角膜移植术，角膜透明度成功恢复。
结论与意义
如果未得到正确识别和处理，这种情况可能会导致诊断和治疗困境。此外，该病例为巩膜接触镜的使用以及内皮角膜移植术在极陡峭角膜中的成功应用提供了信息。
