在抗青光眼的手术史中,首先在角巩膜缘进行环钻术者是EllioT(1909),到目前为止青光眼的手术方式已有数十余种,均各显千秋。如效果较好的虹膜嵌顿术,除不能保证园瞳外,术后点散瞳剂易诱发对侧青光眼。而环钻术,因其有致命的弱点:初期引流过畅,影响眼内无血管组织的代谢;晚期易引起球内感染,因而几乎被淘汰。当然,抗青光眼最理想的术式,是设有阀门装置,当眼压升高时阀门开放,低时关闭,使青光眼病人的眼压长期维持在一个安全的水平上。作者设想在环钻术的钻孔中,放置一个特殊的植入物,暂定名为铆钉。使
Glaucoma in the history of surgery, the first in the limbal ring edge drilling surgery who is EllioT (1909), so far the surgical methods of glaucoma has been more than a dozen species, all significant Xianqiu. Such as the better iris incarceration, in addition to the park pupil can not be guaranteed, postoperative mydriatic agents easily induce contralateral glaucoma. The Central drilling surgery, because of its fatal weakness: initial drainage too smooth, affecting the metabolism of blood vessels without the eye; late easily lead to intracranial infection, which is almost eliminated. Of course, the best anti-glaucoma surgery is a valve device, when the intraocular pressure when the valve is open, closed at low, glaucoma patients with long-term intraocular pressure maintained at a safe level. The authors envisaged placement of a special implant in the percussion drill, tentatively named Rivet. Make
