在以前的研究中，我们通过立体显微放射摄影技术观察了人眼的滤过器。这些技术在证实前房和巩膜外静脉系统之间存在开放通道方面具有重要价值。用不透射线的二氧化钍溶液（Thorotrast）灌注这些通路，发现了延伸到巩膜外层的复杂血管闭塞网络和外周角膜中的复杂血管弓。然而，这种方法并没有最终显示出进入和离开施莱姆氏管的开口，也没有得到这些通道的数量和大小的精确定量数据。看来需要采用不同的方法来进行这种测定。在血管研究中，梯度球灌注技术在确定血管尺寸方面是有用的。
In a previous study 1 we visualized by stereomicroradiographic techniques the filtration apparatus of the human eye. These techniques were valuable in confirming the existence of an open pathway between the anterior chamber and the episcleral venous system. The perfusion of these pathways with a radiopaque solution of thorium dioxide (Thorotrast) revealed both the intricate anastomosing network of vessels extending to the episclera and the elaborate vascular arcade in the peripheral cornea. However, this method did not show conclusively the openings into and out of Schlemm's canal, nor did it yield precise quantitative data on the number and size of these channels. It appeared that a different method would be required for such determinations. In vascular research the technique of perfusion with graded spheres has been useful in determining the size of blood vessels.2 It seemed reasonable to suppose that this method would be applicable to the sizing of the
