Three patients are described in whom full-thickness glaucoma filtering procedures were complicated by marked extension of the bleb over the cornea, with subsequent symptoms that required surgical intervention. The surgical management in each case involved blunt dissection of the bleb from the cornea, with revision of the remaining portion of the bleb differing in each case according to the intraoperative findings. Light microscopic examination of one surgical specimen revealed a markedly attenuated epithelium covering hydropic corneal stroma. The authors postulate that the mechanism of formation involves aqueous humor dissection between corneal epithelium and stroma, leading to abnormal hydration of the superficial lamellae.
本文描述了3例患者，他们接受了全层青光眼滤过手术，术后出现滤过泡明显延伸至角膜表面的并发症，并伴有需要手术干预的后续症状。每例患者的手术处理均包括钝性分离角膜上的滤过泡，根据术中发现，每例患者剩余滤过泡部分的修复方式有所不同。对一份手术标本进行光镜检查发现，角膜上皮显著变薄，覆盖着水肿的角膜基质。作者推测，其形成机制涉及房水在角膜上皮和基质之间的剥离，导致浅层板层异常水化。
