An 82-year-old man with severe primary open-angle glaucoma on maximal medical therapy underwent an ab externo closed conjunctival Xen45 device insertion with mitomycin C. The surgery was uncomplicated, with a first postoperative day intraocular pressure of 4 mm Hg and visual acuity of 20/40 OD. Ten days later, the patient presented with an intraocular pressure of 5 mm Hg and a visual acuity of counting fingers at 5 feet. Examination showed Seidel negative bleb, shallow anterior chamber, and large nonappositional choroidal detachments. Medical therapy with steroids and cycloplegia was initiated. One week later, the serous choroidal detachments became appositional, and Xen explantation and surgical drainage of the choroidal detachment was performed. Postoperatively, the vision improved to 20/60. Significant choroidal detachments can occur after XEN45 implantation requiring surgical intervention.

一名 82 岁男性患有严重的原发性开角型青光眼，正在接受最大程度的药物治疗，接受了外部封闭式结膜 Xen45 装置植入丝裂霉素 C。手术并不复杂，术后第一天眼压为 4 毫米汞柱，视力也恢复正常20/40 OD。10天后，患者眼压为5毫米汞柱，视力达到5英尺数手指的视力。检查显示 Seidel 阴性滤泡、浅前房和大的非并置脉络膜脱离。开始使用类固醇和睫状肌麻痹剂进行药物治疗。1周后，浆液性脉络膜脱离并置，对脉络膜脱离进行Xen移植和手术引流。术后，视力改善至20/60。XEN45 植入后可能会发生严重的脉络膜脱离，需要手术干预。
