The vitreous humor is the largest structure in the eye. It is a transparent, jellylike humor that fills the posterior cavity of the eye. As a results, the vitreous functions to transmit light, to maintain the shape of the eye, and to help maintain the normal position of the retina. Embriologically, the vitreous is described as three components: primary, secondary and tertiary vitreous. The vitreous is 98% water, collagen and hyaluronic acid comprise 1-2%. The vitreous proper has very few cells and most of them are hyalocytes. Variable persistence of the hyaloid occurs in association with many other type of malformations. Small remnants of the hyaloids vasculature are encountered behind the central posterior lens capsule. Frequently seen vitreous abnormalities include vitreous strands, asteroid hyalosis, hemorrhage and infiltration within inflammatory cells. Vitreous opacities tend to move slightly or oscillate within the gel vitreous after eye movements.
