Explantation of glaucoma valve implants may be complicated by wound closure problems. Prolonged implantation of these valves can lead to development of corneo-scleral fistulas that may not be adequately sealed with the use of sutures alone. The authors report the use of processed pericardium as tissue replacement material for the repair of such fistulas. A 45-year-old woman underwent explantation of a Baerveldt glaucoma valve implant, resulting in the development of a corneo-scleral fistula. To repair the fistula, processed pericardium was inserted into it and secured with 10-0 nylon sutures. Postoperatively, a good wound seal was achieved with no leakage of aqueous humor from the anterior chamber, nor any inflammation. Processed pericardium appears to be an effective tissue replacement material for sealing corneo-scleral fistulas.
青光眼瓣膜植入物的取出可能因伤口闭合问题而变得复杂。这些瓣膜的长期植入会导致角巩膜瘘的形成，仅使用缝线可能无法充分封闭。作者报告了使用处理过的心包作为组织替代材料来修复此类瘘管。一名45岁女性接受了Baerveldt青光眼瓣膜植入物的取出，导致了角巩膜瘘的形成。为了修复瘘管，将处理过的心包插入其中并用10-0尼龙缝线固定。术后，实现了良好的伤口封闭，前房没有房水渗漏，也没有任何炎症。处理过的心包似乎是用于封闭角巩膜瘘的一种有效的组织替代材料。
