Vitreous Humor
Vitreous Humor
The Vitreous Humor is the clear gel that fills the space between the lens and the retina of the eye. It makes up approximately two thirds of the eye's volume, giving it a round shape. The vitreous humor is composed of water (99%), collagen, hyaluronic acid, phagocytes, and a variety of salts and sugars.
Structure[edit | edit source]
The vitreous humor is a transparent, colorless, gelatinous mass that fills the space in the eye between the lens and the retina. It is surrounded by a layer of collagen called the vitreous membrane or hyaloid membrane. The vitreous humor is not a static substance and it is continually being produced and reabsorbed.
Function[edit | edit source]
The primary function of the vitreous humor is to provide structural support to the eye, and to help transmit light from the lens to the retina. It also helps to maintain the shape of the eye and keep the retina in place.
Clinical significance[edit | edit source]
Changes in the vitreous humor can lead to a number of eye conditions. These include vitreous detachment, vitreous hemorrhage, and vitreous floaters. In addition, the vitreous humor can become clouded or filled with debris, which can affect vision.
