Posterior Vitreous Detachment

Posterior Vitreous Detachment

 

Most of the eye's interior is filled with vitreous, a gel-like substance that helps the eye maintain a round shape. There are millions of fine fibres intertwined within the vitreous that are attached to the surface of the retina, the eye's light-sensitive tissue. As we age, the vitreous slowly shrinks, and these fine fibers pull on the retinal surface. Usually the fibers break, allowing the vitreous to separate and shrink from the retina.

 

The PVD process can take varying length of time: from hours to months. It is believed by some to take place within 4-6 weeks.

For some patients the PVD process can be symptomatic. Some patients experience flashes, floaters and decreased vision.
