title: Corrosion casts of the suprachoroidal space and uveoscleral drainage routes in the pig eye.
abstract: Eyes from pigs 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. The outer (scleral) surface of the casts was rough, with a fish-scale-like appearance caused by fine lamellas between the sclera and choroid, running from the inner layers of the sclera traversing the space anteriorly to the choroid. Frequently, irregular, Y-shaped branches deriving from the outer surface of the casts were observed. They corresponded to the perivascular space of the vortex veins and represent a possible uveoscleral drainage route for aqueous humour.
