Abstract：
BACKGROUND: Glaucoma is a progressive optic neuropathy and it is the main cause of irreversible blindness worldwide. Intraocular pressure (IOP) is the only modifiable one and trabeculectomy is commonly considered the surgical \"gold standard\" to decrease IOP. In particular cases, other kind of surgeries, as the Ahmed Glaucoma Valve (AGV) implant, are a reliable alternative. Usually, the silicone tube of AGV surgery is inserted into the anterior chamber. Sometimes it is necessary to place the AGV silicone tube in the ciliary sulcus, especially in cases of endothelial decompensation. This surgical procedure is not always easy to perform.
METHODS: This article describes and presents a technique for inserting the AGV tube into the posterior chamber using a guide-wire, in a total of 12 cases are reported. This procedure has been mostly applied in a group of pseudophakic patients who need AGV placement to control elevated IOP. In exceptional situations, this procedure was applied in pseudophakic patients previously with AGV tube implanted in the anterior chamber and with loss of endothelial cells or in phakic patients with previously implanted AGV anterior chamber tube, simultaneously to cataract surgery.
CONCLUSIONS: The purpose of these cases presentations attended at our service is to demonstrate the passage of the AGV silicone tube was performed with the aid of a guide wire.

摘要：
背景：青光眼是一种进行性视神经病变，是全球范围内不可逆性失明的主要原因。眼内压（IOP）是唯一可改变的眼压，小梁切除术通常被认为是降低眼压的手术“金标准”。在特定情况下,其他类型的手术，作为Ahmed青光眼瓣膜（AGV）植入物，是一个可靠的选择。通常,AGV手术的硅胶管插入前房。有时有必要将AGV硅胶管放在睫状沟中，尤其是内皮代偿失调的病例。这种外科手术并不总是容易执行。
方法：本文描述并介绍了一种使用导丝将AGV管插入后房的技术，总共报告了12例。此程序已主要应用于一组需要放置AGV以控制IOP升高的假晶状体患者。在特殊情况下,该方法适用于先前在前房植入AGV管并有内皮细胞丢失的假晶状体患者或先前植入AGV前房管的有晶状体患者，同时进行白内障手术。
结论：在我们的服务中参加的这些病例介绍的目的是证明AGV硅胶管的通过是在导丝的帮助下进行的。
