Histology of vitreous in its gel and fluid forms.
Low- and high-power microscopic examination of just-dried (without flame) fresh smears of gel, semi-gel, and fluid human and rabbit vitreous without stain showed that solid gel vitreous is composed of two types of transparent network, i.e., thick fibers in meshes of which there is another fine fibril network and both types of fluid vitreous, the fiber and fibril networks, show stages in transformation to transparent granules; this is why fluid vitreous remains transparent.
