We report a case in which intraocular endoscopy clarified the cause of Ahmed glaucoma valve (AGV) failure with a cloudy cornea. A 42-year-old patient with glaucoma underwent AGV implant surgery to treat secondary glaucoma due to chronic iridocyclitis in his left eye. After AGV, he developed bullous keratopathy (BK) in that eye. After Descemet stripping automated endothelial keratoplasty (DSAEK) was performed to treat BK, the intraocular pressure (IOP) increased and early failure of the DSAEK resulted again in a cloudy cornea. We could not precisely detect any cause of AGV failure with ordinary imaging instrumentation. An intraocular endoscope was used to determine that cause, and we found that the fibrous tissue occluded the tube of the AGV. The IOP decreased soon after the tissue was removed. We conclude that intraocular endoscopy was useful for diagnosing AGV failure with BK.

眼内镜解决了 Ahmed 青光眼瓣膜的管阻塞

我们报告了一个案例,其中眼内镜明确了 Ahmed 青光眼瓣膜 (AGV) 失败的原因,角膜混浊。一名 42 岁的青光眼患者因左眼慢性虹膜睫状体炎接受 AGV 植入手术治疗继发性青光眼。在 AGV 之后,他那只眼睛出现了大疱性角膜病变 (BK)。在进行了 Descemet 剥离自动内皮角膜移植术 (DSAEK) 来治疗 BK 后,眼压 (IOP) 增加并且 DSAEK 的早期失败再次导致角膜混浊。我们无法使用普通成像仪器精确检测 AGV 故障的任何原因。使用眼内窥镜确定该原因,我们发现纤维组织阻塞了 AGV 的导管。取出组织后,IOP 很快就下降了。
