Abstract

INTRODUCTION

This report describes the first known case of late-onset intrusion of an intrastromal ring segment into the anterior chamber due to posterior migration of a ring segment. To our knowledge, intrastromal ring segment penetration has only been shown to occur in the intraoperative or immediate postoperative period. We postulate that the perforation in this case is due to progressive thinning of the cornea, possibly in combination with habitual eye rubbing.

CASE REPORT

A 44-year-old man presented with acute corneal hydrops related to penetration of Descemet's membrane and endothelium by an intrastromal ring segment implanted 7 years prior. Removal of the ring segment resulted in an anterior chamber fistula that directed fluid through the ring segment tunnel to the ocular surface. Leakage of aqueous humor was successfully controlled, and corneal edema gradually resolved.

CONCLUSION

This case indicates the need for long term monitoring of ring segment proximity to the posterior corneal surface, especially in patients with ectatic ocular conditions and/or habitual eye rubbing behavior.

摘要

引言

本报告描述了首例已知的因基质内环片后移导致基质内环片迟发性侵入前房的病例。据我们所知，基质内环片穿孔仅在术中或术后即刻被证实会发生。我们推测该病例中的穿孔是由于角膜逐渐变薄，可能还伴有习惯性揉眼。

病例报告

一名44岁男性因7年前植入的基质内环片穿透后弹力层和内皮而出现急性角膜水肿。取出环片导致前房瘘，使房水通过环片隧道引流至眼表。房水渗漏得到成功控制，角膜水肿逐渐消退。

结论

该病例表明需要长期监测环片与角膜后表面的距离，尤其是对于患有扩张性眼部疾病和/或有习惯性揉眼行为的患者。
