The Vitreous: Bird’s Eye View

  • A. Neetens


The vitreous is a simple connective tissue. The postnatal vitreous contains cells— hyalocytes— that synthesize hyaluronic acid, collagen, and probably other vitreous components. The hyalocytes have functional characteristics of a macrophage. The question arises as to whether they may develop actine filaments and show evidence of contractility, like cells invading the vitreous from adjacent tissues. Fibroblasts, retinal pigment epithelial cells, and vascular endothelial cells are all capable of proliferating along vitreoretinal membranes and can penetrate into the vitreous cavity through a discontinuity in the internal limiting lamina that may result from damage to Müller cells.
