To visualize the suprachoroidal space and to study the morphology of possible uveoscleral drainage routes in the human eye.
Indian ink stained gelatine was injected directly into the suprachoroidal space of 7 human donor eyes. Those quadrants where gelatine appeared in the episcleral venous network were cut in their entirety in consecutive sections and examined by light microscopy.
Gelatine was observed in the connective tissue surrounding scleral vessels and nerves. Gelatine was also traceable in fine, endothelium-lined channels at the inner aspect of the anterior sclera. These channels seemed to originate at the inner surface of the sclera, close behind the scleral spur, and communicate with the intrascleral venous plexus.
Fluid is drained from the suprachoroidal space through the perivascular and perineural spaces of scleral blood vessels and nerves. In addition, this study indicates that there are preformed channels at the inner aspect of the anterior sclera, capable of draining fluid directly into scleral veins.
观察脉络膜上腔，并研究人眼可能的葡萄膜巩膜引流途径的形态。
将印度墨汁染色的明胶直接注入7只人供体眼的脉络膜上腔。在连续切片中，将明胶出现在巩膜静脉网的象限完整切除，并进行光学显微镜检查。
在巩膜血管和神经周围的结缔组织中观察到明胶。在前巩膜内侧的细小内皮衬里通道中也可追踪到明胶。这些通道似乎起源于巩膜内表面，在巩膜嵴后方附近，并与巩膜内静脉丛相通。
液体从脉络膜上腔通过巩膜血管和神经的血管周隙和神经周隙引流。此外，本研究表明，在前巩膜内侧存在预先形成的通道，能够将液体直接引流到巩膜静脉中。
