The vitreous is a clear gel-like tissue, clear and bright. The main component is a reticular frame composed of collagen fibers filled with adsorbed molecules of hyaluronic acid, which stabilizes the properties of the vitreous gel and ensures that the vitreous and its surrounding retina are cushioned when the eye is turned or subjected to vibration. And the visual field is clear and flawless, ensuring sharpness of vision. If an opaque body other than the normal structure appears in the vitreous, it is called vitreous opacity.
