Floaters and Flashes
can threaten eyesight
What are floaters?
You may sometimes see small
specks or clouds moving in your field of vision. These are
called floaters. You can often see them when looking at a
plain background, like a blank wall or blue sky. Floaters
are actually tiny clumps of gel or cells inside the
vitreous, the clear gel-like fluid that fills the inside of
your eye. While these objects look like they are in front of
your eye, they are actually floating inside it.
What you see are the shadows they
cast on the retina, the layer of cells lining the back of
the eye that senses light and allows you to see. Floaters
can appear as different shapes, such as little dots,
circles, lines, clouds, or cobwebs.
Are floaters ever serious?
L
The retina can tear if the
shrinking vitreous gel pulls away from the wall of the eye.
This sometimes causes a small amount of bleeding in the eye
that may appear as new floaters. A torn retina is always a
serious problem, since it can lead to a retinal detachment.
You should see your
ophthalmologist as soon as possible if:
·
Even one new floater appears
suddenly:
·
You see sudden flashes of light.
·
If you notice other symptoms, like
the loss of side vision, you should see your
ophthalmologist.
Can floaters be removed?
Floaters may be a symptom of a
tear in the retina, which is a serious problem. If a retinal
tear is not treated, the retina may detach from the back of
the eye. The only treatment for a detached retina is
surgery. Other floaters are harmless and fade over time or
become less bothersome, requiring no treatment.
