A 62-year-old woman with neovascular glaucoma underwent filtering surgery with the Ahmed glaucoma valve (New World Medical, Inc., Rancho Cucamonga, CA). Intraoperative hypotony secondary to a defective valve was noted and managed by excising the valve mechanism. The implant was then treated as if it was non-valved by placement of an obturator suture. The postoperative course was unremarkable for a non-valved implant. This case demonstrates how intraoperative hypotony secondary to overfiltration of an Ahmed glaucoma valve implant can be successfully managed by converting to a non-valved implant.
一名62岁的新生血管性青光眼女性患者接受了使用艾哈迈德青光眼引流阀（美国加利福尼亚州兰乔库卡蒙加市新世界医疗公司）的滤过手术。术中发现因引流阀缺陷导致的低眼压，并通过切除引流阀装置进行处理。然后通过放置封闭缝线将植入物当作无阀植入物来处理。术后过程对于无阀植入物而言并无异常。该病例表明，通过将艾哈迈德青光眼引流阀植入物转换为无阀植入物，可以成功处理因该植入物过度滤过导致的术中低眼压情况。
