Floaters

What are floaters?


Floaters are the small specks or clouds you may sometimes see moving in your fields of vision. 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 jelly-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. What you see are the shadows they cast on the retina, the nerve layer at the back of the eye that senses light and allows you to see.


Floaters can have different shapes: little dots, circles, lines, clouds or cobwebs.


What causes floaters?


When people reach middle age, the vitreous gel may start to thicken or shrink, forming clumps or strands inside the eye. The vitreous gel pulls away from the back wall of the eye, causing a posterior vitreous detachment. It is a common cause of floaters.


Posterior vitreous detachment is more common for people who:


                                *are nearsighted


                                *have undergone cataract operations


                                *have had YAG laser surgery of the eye


                                *have had inflammation inside the eye


 


Are floaters ever serious?


 


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. Seek medical attention as soon as possible if:


                               


                                *even one new floater appears suddenly


                                *you see sudden flashes of light


 


If you notice other symptoms like loss of side vision, return to your ophthalmologist.


 


What can be done about floaters?


 


Floaters can get in the way of clear vision, which may be quite annoying especially if you are trying to read. You can try moving your eyes, looking up and then down to move the floaters out of the way. While some floaters may remain in your vision, many of them will fade over time and become less bothersome. Even if you have had some floaters for years, you should have an eye examination immediately if you notice new ones.
