Fig 5. Histopathologic changes of retia after solvent infusion.

A, Separation of few endothelial cells in 1 retial artery (arrow) (hematoxylin-eosin; original magnification, 200x). Rete was exposed to 0.8 mL of DMSO per 60 seconds.

B, Right-sided rete of swine 8 exposed to 0.8 mL of glycofurol 75 per 60 seconds shows arterial wall hyperplasia, including all vessel layers (hematoxylin-eosin; original magnification, 200x).

C, Left-sided rete of swine 12 exposed to 0.8 mL of solketal shows endothelial denuding of several microarteries (arrows) (hematoxylin-eosin; original magnification, 200x).

D, Note intact internal elastic lamina within these vessels (arrows) (Van Gieson’s elastic; original magnification, 200x).
