Vitreous Detachment (and Floaters)
OVERVIEW
The vitreous space is
located posteriorly between the
lens of the eye
and the retina. It is filled with a material called vitreous which
is similar to clear Jell-O. As we age, the normal jelly-like
consistency of the vitreous begins to liquefy. The vitreous may
contract and pull away from its natural attachments on the inside
surface of the eye. When it pulls free, it is often accompanied by
light flashes and the appearance of a new black spot or floater.
This is not dangerous, but it can be accompanied by more serious eye
conditions such as retinal tears and vitreous hemorrhage. These
occur when the strong attachments of the vitreous to the retina do
not separate properly, tearing the retina or retinal blood vessels.
This often leads to new floaters and persistent light flashes. It is
suggested that anyone with symptoms of a vitreous detachment have an
eye examination to make certain that a more serious problem is not
present.
Normal
floaters are not dangerous and are caused by tiny specks of tissue
inside the vitreous. When light hits these pieces of tissue, it
creates shadows on the retina that appear to float across your field
of vision.
It may appear that these specks are on the front surface of your eye, but they are actually inside. Except in rare circumstances, floaters are no cause for alarm and no treatment is necessary. However, a sudden increase in new floaters may indicate a problem, and an eye examination is recommended if this occurs.
