To report the clinical outcome of a surgical technique for insertion of the silicone tube of a Baerveldt glaucoma implant (BGI) in the posterior chamber sulcus.
Non-comparative, interventional case series. Eight eyes of eight patients, with a follow-up of at least 18 months, who underwent insertion of a BGI with the silicone tube placed in the posterior chamber sulcus between 1998 and 2005 were included. Control of intraocular pressure (IOP), number of pressure-lowering medications, visual acuity and surgical complications were recorded.
Eight eyes of eight patients (mean (range) age 76.4 (62-94) years) were included in the study. The IOP was reduced from a preoperative mean (SD) of 28.2 (14.4) to 12.6 (5.8) mm Hg at 18 months. The mean (SD) number of preoperative medications for IOP control was reduced from 2.8 (1.5) to 1.3 (1.5) medications in the same period. No complications were observed during surgery or follow-up.
Placement of the silicone tube in the posterior chamber sulcus is a safe and effective alternative technique for IOP control in patients with pseudophakia. Sulcus placement may reduce the likelihood of corneal endothelial loss and avoid the need for pars-plana vitrectomy and posterior segment tube insertion in complicated eyes.
报告一种将Baerveldt青光眼植入物（BGI）硅胶管植入后房沟的手术技术的临床结果。
非对照性干预病例系列。纳入1998年至2005年间接受BGI植入且硅胶管置于后房沟的8例患者的8只眼，随访至少18个月。记录眼压（IOP）控制情况、降眼压药物数量、视力及手术并发症。
研究纳入8例患者的8只眼（平均（范围）年龄76.4（62 - 94）岁）。18个月时眼压从术前平均（标准差）28.2（14.4）mmHg降至12.6（5.8）mmHg。同期用于眼压控制的术前平均（标准差）药物数量从2.8（1.5）种降至1.3（1.5）种。手术及随访期间未观察到并发症。
将硅胶管置于后房沟是控制人工晶状体眼患者眼压的一种安全有效的替代技术。沟内放置可降低角膜内皮丢失的可能性，并避免在复杂眼中进行玻璃体切割术和平行部玻璃体切除术及后段管插入的必要性。
