VITREOUS DETACHMENT

WHAT IS 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 fibers 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. This is a vitreous detachment.

WHO IS AT RISK FOR VITREOUS DETACHMENT?

A 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.

SYMPTOMS OF VITREOUS DETACHMENT

As the vitreous shrinks, it becomes somewhat stringy, and the strands can cast tiny shadows on the retina that you may notice as floaters, which appear as little “cobwebs” or specks that seem to float about in your field of vision. If you try to look at these shadows they appear to quickly dart out of the way.

 

One symptom of a vitreous detachment is a small but sudden increase in the number of new floaters. This increase in floaters may be accompanied by flashes of light (lightning streaks) in your peripheral (or side) vision. In most cases, either you will not notice a vitreous detachment, or you will find it merely annoying because of the increase in floaters.
