We could ascertain the mode of action of trabeculectomy by clinical research in more than 370 eyes after the operation and especially by the injection of fluorescein into the anterior chamber in 90 of these eyes. The following drainage mechanisms of the aqueous humor were observed: 1. Outflow through new developed aqueous veins (trabeculectomy-veins), 2. Bulkflow through lymphatic vessels, 3. Diffuse resorption into the subconjunctival tissue, 4. Outflow through normal aqueous veins. The latter mechanism is seldom of great importance. In only three cases passed all of the visible aqueous outflow through normal aqueous veins. In these cases an opening of Schlemm's canal could be assumed. In all of the other eyes we could not find any evidence for an outflow through Schlemm's canal whether there was a filtering bleb or not. This means that from the presence or absence of a visible bleb no conclusion can be drawn as to the mode of action.
我们可以通过对370多只眼睛术后的临床研究，特别是对其中90只眼睛在前房注射荧光素，来确定小梁切除术的作用方式。观察到以下房水引流机制：1. 通过新形成的房水静脉（小梁切除静脉）流出；2. 通过淋巴管的大量流动；3. 扩散吸收进入结膜下组织；4. 通过正常房水静脉流出。后一种机制很少具有重要意义。仅在三例中，所有可见的房水流出均通过正常房水静脉。在这些病例中，可以假定施莱姆管开放。在所有其他眼睛中，无论是否有滤过泡，我们都没有发现任何通过施莱姆管流出的证据。这意味着，从是否存在可见滤过泡，无法推断出其作用方式。
