Eye Diseases - Posterior Vitreous Detachment

What is the Vitreous?

The vitreous gel is a clear, jelly-like substance that fills the inside of the eye. The retina is the nerve tissue that lines the back of the eye. The retina is like the film in a camera that "sends a picture" to the brain. Because the vitreous gel is clear, light rays are able to pass through it to reach the retina. However, any change in the consistency, color or structure of the vitreous can interfere with the transmission of light to the retina, causing visual symptoms.

How does the vitreous change with age?

In young people, the vitreous fills the entire cavity of the eye and has a solid jelly-like consistency. With age, the vitreous becomes more watery, and the gel portion begins to gradually pull away from the retina. This process of pulling away is called Posterior Vitreous Detachment (PVD.)
