Fifteen rabbits were intrathecally perfused with horseradish peroxidase at normal cerebrospinal fluid pressures. Horseradish peroxidase was found in the subarachnoid space around the optic nerve; it permeated the pia and penetrated within the nerve, occupying extracellular spaces between myelinated axons and glial cells up to the area of the lamina cribrosa. Horseradish peroxidase also crossed the perineural sclera and the border tissue of Elschnig to spread into the choroid where it was mostly seen within choriocapillaris, venules, and veins crossing through interendothelial spaces. "Bulk" cerebrospinal fluid absorption in the eye appears to occur through venous drainage in the choroid and SAS.
在正常脑脊液压力下，对15只兔子进行鞘内注射辣根过氧化物酶。在视神经周围的蛛网膜下腔发现了辣根过氧化物酶；它穿透软脑膜并进入神经内部，占据有髓轴突和神经胶质细胞之间的细胞外间隙，直至筛板区域。辣根过氧化物酶还穿过神经周围巩膜和埃尔施尼格（Elschnig）边缘组织，扩散到脉络膜，在那里主要见于穿过内皮间隙的脉络膜毛细血管、小静脉和静脉内。眼中“大量”脑脊液的吸收似乎是通过脉络膜和蛛网膜下腔的静脉引流来实现的。
