Electron microscopic serial sections in a tangential plane through the inner wall of Schlemm's canal and the trabecular meshwork in normal and glaucomatous eyes revealed a characteristic network of elastic-like fibers (cribriform plexus), which is directly connected to the inner wall endothelium by a special fiber system (connecting fibrils). This cribriform plexus is also connected to the ciliary muscle system. Ciliary muscle tendons were found that not only show the same fine structure as the cribriform plexus but also join it. The ciliary muscle tone can therefore directly influence the fiber system of the cribriform plexus and its connections to the inner wall of Schlemm's canal. in eyes with chronic simple glaucoma, three types of plaques in the cribriform meshwork have been described after studies of sagittal sections. A comparison with tangential sections of the same piece of tissue shows that plaques of type II and III are in fact sections through the cribriform plexus and that only type I plaques are a separate entity.
对正常眼和青光眼眼的施莱姆管内壁及小梁网进行的电子显微镜连续切片，这些切片沿切线平面制作，结果显示出一种由弹性样纤维构成的特征性网络（筛状丛），该网络通过一种特殊的纤维系统（连接纤维）直接与内壁内皮相连。这种筛状丛也与睫状肌系统相连。研究发现，睫状肌腱不仅与筛状丛具有相同的精细结构，而且与之相连。因此，睫状肌张力可直接影响筛状丛的纤维系统及其与施莱姆管内壁的连接。在慢性单纯性青光眼眼中，对矢状切片进行研究后，已描述了筛状网中的三种类型的斑块。对同一块组织的切线切片进行比较后发现，II型和III型斑块实际上是筛状丛的切片，只有I型斑块是一个单独的实体。
