What is the vitreous body?

The vitreous body is the transparent gel-like substance that fills the space between the lens and the retina in the posterior chamber of the eyeball. Its primary functions include maintaining the shape of the eye, providing structural support, and allowing light to pass through to the retina without obstruction. The vitreous body is composed of a network of collagen fibers and hyaluronic acid, which help keep it transparent.

This clarity is essential for optimal vision, as any cloudiness in the vitreous can interfere with light transmission and potentially impact sight. Its unique composition and location are what differentiate it from other structures in the eye, such as the outer layer, which consists of the cornea and sclera, or the muscles that control eye movement.
