Traditional gonioscopic practice assumes that, if most of the angle is gonioscopically closed, intraocular pressure increases. Evidence is produced to show that this is fallacious, because at its inception angle closure is iridocorneal contact occurring on the corneal side of the limbus. Although the angle cannot be seen by means of a gonioscope, there is initially no iridotrabecular contact. It is only after pressure increases that iris is pushed against trabecular meshwork and the angle is truly closed.
传统的前房角镜检查认为,如果大部分房角在前房角镜下关闭,眼压就会升高。有证据表明这种观点是错误的,因为在房角关闭开始时,是角膜缘角膜侧发生虹膜角膜接触。虽然通过前房角镜看不到房角,但最初并没有虹膜小梁接触。只有在眼压升高后,虹膜才会被推压到小梁网,房角才真正关闭。
