Vitreous The main functions of the vitreous are to transmit light to the retina, and to exert enough pressure to keep the retinal layers tightly pressed together. This pressure helps maintain the round shape of the eye so the lens can focus sharp images on the retina. The vitreous is very different from the aqueous humor.

Vitreous and Aqueous Humor In Depth: Vitreous and Aqueous Humor. Gel-like fluids inside the eye help it maintain its shape, which plays an important role in overall eye health. These substances are called the vitreous humor and aqueous humor. Vitreous is a transparent substance that is around 99 percent water. The remaining one percent is collagen and hyaluronic acid, which cause vitreous to have a gelatinous consistency.

- Vitrectomy is a surgical procedure undertaken by a specialist where the vitreous humor gel that fills the eye cavity is removed to provide better access to the retina. This allows for a variety of repairs, including the removal of scar tissue, laser repair of retinal detachments and treatment of macular holes.

- Top 10 unbelievable historical concurrencies. The vitreous or vitreous humor is a clear fluid which fills the eye between the lens and the retina. This fluid helps the eye hold its shape, with light being transmitted through it to the retina.As people age, they sometimes develop problems in this area of the eye which lead to floaters and dark spots in the vision. vitrectomy may be used to address issues caused by the vitreous humor. Vitreous detachment may cause some individuals to experience floaters in their line of vision. The vitreous humor is a clear gel which fills most of the interior of the eyeball. An ophthalmologist can diagnose detachment after an eye exam.

Vitreous After passing through the cornea, aqueous humor and lens (anterior segment of the eye), light finally enters the vitreous (also called vitreous humor). is a transparent, jelly-like substance that fills the vitreous body. The vitreous body is the space created by the lens, retina and optic disc. This is also referred to as the posterior segment of the eye. The main functions of the vitreous are to transmit light to the retina, and to exert enough pressure to keep the retinal layers tightly pressed together. This pressure helps maintain the round shape of the eye so the lens can focus sharp images on the retina. The vitreous is very different from the aqueous humor.

- For the band, see Vitreous Humor. The vitreous humour is the clear gel that fills the space between the lens and the retina of the eyeball of humans and other vertebrates. It is often referred to as the vitreous body or simply the vitreous.he lens, on the other hand, is tightly packed with cells. The vitreous humour has a viscosity two to four times that of water, giving it a gelatinous consistency. It has a refractive index of 1.336.

As one ages, the vitreous undergoes syneresis, in which it becomes more fluid or liquid-like. The pockets of fluid in the vitreous cavity give the patient a sensation of floaters or cobwebs..

Eye Floaters, Flashes And Spots As the vitreous gel tugs on the delicate retina, it might cause a small tear or hole in it. When the retina is torn, vitreous can enter the opening and push the retina farther away from the inner lining of the back of the eye — leading to a retinal detachment.

Posterior Vitreous Detachment - Topic Overview Posterior vitreous detachment (PVD) happens as a normal part of aging. The vitreous gel shrinks and separates from the retina. PVD normally happens over a period of time, and it's something that you won't feel. It happens because the vitreous gel in the middle of your eye begins to change by the time you are 40 or 50. The gel's normal structure breaks down in a process called syneresis.

There are millions of fine fibers intertwined within the vitreous that are attached to the surface of the retina, the eye’s light-sensitive tissue. vitreous detachment is a common condition that usually affects people over age 50, and is very common after age 80. People who are nearsighted are also at increased risk. Those who have a vitreous detachment in one eye are likely to have one in the other, although it may not happen until years later.

- However, vitreous detachment may make you more susceptible to retinal detachment and macular hole formation, which are serious conditions that are known to cause visual loss. Healthy vitreous comprises 80% of the eyeball volume. Vitreous is extraordinarily clear and changes consistency throughout life. The melting and shrinking of the vitreous that causes vitreous detachment is a part of normal aging and generally begins around the age of 50.

Overview Retinal detachment can occur as a result of: A sagging vitreous (VIT-ree-us) — the gel-like material that fills the inside of your eye; Injury; Advanced diabetes; How retinal detachment occurs. Retinal detachment can occur when the gel-like material (vitreous) leaks through a retinal hole or tear and collects underneath the retina.
