Vitreous Detachment
(and Floaters)
A brief explanation
 he vitreous
space 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.
Floaters
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.
