Abstract：
UNASSIGNED: This study aims to present two different types of giant bleb formation following Ahmed Glaucoma Valve (AGV) implantation: an anterior enlarged giant bleb and a posterior enlarged giant bleb.
UNASSIGNED: In Case 1, a 70-year-old Japanese male underwent AGV implantation for neovascular glaucoma in his right eye (OD). Preoperatively, the patient\'s intraocular pressure (IOP) and best corrected visual acuity (BCVA) were 23 mmHg and 0.6, respectively, OD, while using 3 antiglaucoma topical medications. Two months post-surgery, the patient began experiencing double vision. Slit lamp evaluation revealed no abnormalities, IOP and BCVA were 24.0 mmHg and 0.8, respectively, OD. A posteriorly enlarged bleb in the superotemporal quadrant OD was found to be causing displacement on T2-weighted orbital MRI. The patient underwent surgical excision of the anterior bleb wall. By three weeks post-surgery, the double vision resolved; IOP and BCVA were 17 mmHg and 0.7, respectively, and a normal bleb in the slit lamp evaluation was identified OD. In Case 2, a 10-year-old Japanese female underwent AGV implantation for childhood glaucoma associated with congenital cataract OD. Preoperatively, IOP and BCVA were 30 mmHg and 0.5, respectively, OD, while using 3 antiglaucoma topical medications. She underwent pars plana vitrectomy (PPV) in addition to AGV implantation. Seven months post-surgery, slip lamp evaluation revealed an anteriorly enlarged giant bleb that only cause her a cosmetic concern.
UNASSIGNED: There are two types of giant bleb formation following AGV implantation based on the direction of the enlargement: an anterior enlarged giant bleb and a posterior enlarged giant bleb. The introduction of this classification contribute to better understanding and management of this unusual surgical complication.

摘要：
■本研究旨在介绍Ahmed青光眼瓣膜（AGV）植入后两种不同类型的大泡形成：前部扩大的大泡和后部扩大的大泡。
在病例1中，一名70岁的日本男性因右眼新生血管性青光眼（OD）接受了AGV植入。术前,患者的眼压（IOP）和最佳矫正视力（BCVA）分别为23mmHg和0.6，OD,同时使用3种抗青光眼局部药物。手术后两个月,患者开始出现复视。裂隙灯评价无异常,眼压和BCVA分别为24.0mmHg和0.8，OD.在T2加权眼眶MRI上，发现超颞叶象限OD的后部扩大的气泡引起移位。患者接受了前气泡壁的手术切除。手术后三周,复视解决；眼压和BCVA分别为17mmHg和0.7，裂隙灯评价中的正常气泡被鉴定为OD。在案例2中，一名10岁的日本女性因先天性白内障OD相关的儿童青光眼接受了AGV植入。术前,眼压和BCVA分别为30mmHg和0.5，OD,同时使用3种抗青光眼局部药物。除AGV植入外，她还接受了平坦部玻璃体切除术（PPV）。手术后七个月,滑灯评估显示有一个向前扩大的巨大气泡，这只会引起她对化妆品的关注。
■根据扩大的方向，AGV植入后有两种类型的巨大气泡形成：前部扩大的巨大气泡和后部扩大的巨大气泡。这种分类的引入有助于更好地理解和处理这种不寻常的手术并发症。
