Retina Vitreous is cause due to Floaters
You may sometimes see small specks or clouds moving in your field of vision. They are called floaters. You can often see them when looking at a plain background, like a blank wall or blue sky. 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. Floaters can have different shapes: little dots, threads, circles, lines, clouds or cobwebs.
The retina can tear if the shrinking vitreous gel pulls away from the retina. 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 retina specialist as soon as possible if even one new floater appears suddenly or you see sudden flashes of light or if you notice other symptoms like the loss of side vision.
