Human cadaver eyes were studied by corrosion casting technique. Batson's mixture No. 17 (methyl methacrylate) was injected through a sclerotomy into the suprachoroidal space. Following polymerisation of the injected mixture the surrounding tissue was dissolved with 10% natrium hydroxide. Macroscopic and scanning electron microscopic findings in casts of the suprachoroidal space are presented. Due to transscleral drainage of resin from the suprachoroidal space, different types of branches deriving from the outer (scleral) surface of the casts were found. Some of these branches corresponded to the perivascular spaces of both ciliary vessels and vortex veins. In addition, we found branches probably representing channels deriving directly from the suprachoroidal space, communicating with the intrascleral venous plexus. Such channel systems have previously not been described, and their possible relation to the uveoscleral drainage of aqueous humour is discussed.
采用腐蚀铸型技术对人尸体眼睛进行了研究。通过巩膜切开术将巴特森17号混合物（甲基丙烯酸甲酯）注入脉络膜上腔。注入的混合物聚合后，用10%氢氧化钠溶解周围组织。本文展示了脉络膜上腔铸型的宏观和扫描电子显微镜检查结果。由于树脂从脉络膜上腔经巩膜引流，在铸型的外（巩膜）表面发现了不同类型的分支。其中一些分支对应于睫状血管和涡静脉的血管周围间隙。此外，我们还发现了一些分支，可能代表直接源自脉络膜上腔并与巩膜内静脉丛相通的通道。此前尚未描述过此类通道系统，并对其与房水葡萄膜巩膜引流的可能关系进行了讨论。
