Filtering surgery may be complicated by excessive filtration or bleb leak in the postoperative period, resulting in a shallow or flat anterior chamber and choroidal detachment. A glaucoma tamponade shell with a raised inner platform increases the resistance to flow through the fistula, deepening the anterior chamber. Some surgeons apply a pressure patch over the shell to increase the tamponading effect and to prevent rotation of the shell. Nevertheless, the shell may still rotate, resulting in less than adequate tamponade. We describe a technique that prevents rotation of the shell.
滤过性手术在术后可能会因滤过过度或滤过泡渗漏而变得复杂，导致前房变浅或变平以及脉络膜脱离。一种带有凸起内平台的青光眼填塞物外壳可增加通过瘘管的流动阻力，加深前房。一些外科医生会在外壳上施加压力贴片以增强填塞效果并防止外壳旋转。然而，外壳仍可能会旋转，导致填塞效果不佳。我们描述了一种防止外壳旋转的技术。
