目的：报道Baerveldt青光眼引流植入术术后并发症的发生率及危险因素。方法：回顾性分析1992年10月1日至1996年10月31日在佛罗里达州迈阿密巴斯科姆帕尔默眼科研究所接受Baerveldt青光眼引流植入的所有患者的医疗记录，以确定人口统计学特征、术前和术后眼压和并发症。采用Student t检验和Fisher精确检验对变量进行分析，以确定迟发性术后脉络膜上出血与各种潜在危险因素的关系。结果：103例患者共鉴定出107只眼。4眼（4%）发生脉络膜上出血，发病时间为植入后3 ~ 33天。2眼（2%）有脉络膜积液需要手术引流，20眼（19%）有低脉络膜积液只需要密切观察。管内堵塞5眼（5%）。4只眼（4%）有水误导，2只眼（2%）有角膜失代偿，1只眼（1%）有眼内炎、眼管移位、角膜溃疡、前房积血和植入物移位。年龄较大（P= 0.04）、术后脉络膜积液（P= 0.03）、插管后立即出现低眼压（P= 0.03）、高血压（P= 0.08）、动脉粥样硬化（P= 0.09）的患者更容易发生脉络膜上出血。结论：与最近的报道相比，本研究中观察到Baerveldt种植的严重术后并发症发生率较低。严重并发症的危险因素与小梁切除术相似。
Objectives: To report the incidence and identify risk factors of postoperative complications after Baerveldt glaucoma drainage implantation.Methods: A retrospective review of the medical records of all patients at the Bascom Palmer Eye Institute, Miami, Fla, who underwent placement of a Baerveldt glaucoma drainage implant from October 1, 1992, through October 31, 1996, to determine demographic characteristics, preoperative and postoperative intraocular pressures, and complications. Variables were analyzed using the Student t test and Fisher exact test to determine the association between delayed postoperative suprachoroidal hemorrhage and various potential risk factors.Results: A total of 107 eyes of 103 patients were identified. Suprachoroidal hemorrhage occurred in 4 eyes (4%),with onset ranging from 3 to 33 days after implantation. Two eyes (2%) had choroidal effusions requiring surgical drainage, and 20 eyes (19%) had low choroidal effusions requiring only close observation. Tube blockage was observed in 5 eyes (5%). Four eyes (4%) had aqueous misdirection, 2 eyes (2%) had corneal decompensation, and 1 eye (1%) each had endophthalmitis, tube migration, corneal ulcer, hyphema, and implant migration. Patients who were older (P=.04) or had postoperative choroidal effusions (P=.03), low intraocular pressure immediately after the tube opened (P=.03), hypertension (P=.08), or atherosclerosis (P=.09) were more likely to develop suprachoroidal hemorrhage.Conclusions: A lower incidence of serious postoperative complications was observed in Baerveldt implantations in this study when compared with a recent report. Risk factors for serious complications were similar to trabeculectomy.
