What are floaters?
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 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. This is a common cause of floaters.
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. You should see your ophthalmologist as soon as possible if:
- Even one new floater appears suddenly
- You see sudden flashes of light
