In patients with significant preoperative comorbidities, prolonged activity restrictions beyond 2 weeks after Xen45 surgery may mitigate the risks of delayed SCH.
To report the first case to date of delayed suprachoroidal hemorrhage (SCH) not associated with hypotony 2 weeks after the placement of the Xen45 gel stent.
An 84-year-old white man with significant cardiovascular comorbidities underwent uneventful ab externo implantation of a Xen45 gel stent for asymmetric progression of severe primary open angle glaucoma. The patient had a reduction in intraocular pressure by 11 mm Hg on postoperative day 1 and maintained preoperative visual acuity. The intraocular pressure remained stable at 8 mm Hg on multiple postoperative visits until the patient developed a SCH at postoperative week 2 immediately after a light session of physical therapy. The patient was treated medically with topical cycloplegic, steroid, and aqueous suppressants. He maintained preoperative visual acuity throughout the postoperative course and had resolving SCH without the need for surgical intervention.
This is the first report of a delayed presentation of SCH in the absence of hypotony after ab externo implantation of the Xen45 device. The possibility of this vision-threatening complication should be considered as part of the risk assessment and included in the consent process for the gel stent. In patients with significant preoperative comorbidities, prolonged activity restrictions beyond 2 weeks after Xen45 surgery may mitigate the risks of delayed SCH.
在术前合并症严重的患者中,Xen45 手术后超过 2 周的长时间活动限制可能会降低延迟性脉络膜上腔出血(SCH)的风险。
报告首例与 Xen45 凝胶支架放置后 2 周内眼压降低无关的延迟性 SCH。
一名 84 岁白人男性,有严重的心血管合并症,行外路植入 Xen45 凝胶支架治疗不对称性进展性严重原发性开角型青光眼。术后第 1 天,患者眼压下降 11mmHg,术前视力保持不变。多次术后访视眼压稳定在 8mmHg,直到术后第 2 周,患者在一次短暂的物理治疗后立即发生 SCH。患者接受了局部睫状肌麻痹剂、类固醇和房水抑制剂的药物治疗。他在整个术后过程中保持术前视力,SCH 逐渐吸收,无需手术干预。
这是首例 Xen45 设备外路植入术后无眼压降低而出现延迟性 SCH 的报告。在风险评估中应考虑到这种威胁视力的并发症的可能性,并将其纳入凝胶支架的知情同意过程中。在术前合并症严重的患者中,Xen45 手术后超过 2 周的长时间活动限制可能会降低延迟性 SCH 的风险。
