Causes of DVS

What causes DVS (eye floaters)?

The development of vitreous opacities (floaters) is typically attributed to the degeneration of the vitreous. Degeneration allows the collagen fibrils within the vitreous to condense into clumps and knots. Although floaters resulting from vitreous degeneration are usually associated with middle-age, children and teens have also reported vitreous opacities. These "younger" floaters may be attributed to debris of embryonic origin remaining in the eye. Other events which may precipitate floaters include eye injury and eye surgery (e.g. lens replacement, corneal refractive surgery, etc.). Floaters and are also believed to be more common in nearsighted eyes.

Are floaters ever serious?

Floaters are not usually physically harmful by themselves; however, they can be a symptom of a more serious problem. As the vitreous degenerates it collapses and shrinks. If it does not cleanly separate from the retina it may pull and tear the retina. This sometimes causes a small amount of bleeding in the eye that may appear as 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 or you see sudden flashes of light. If you notice other symptoms, like the loss of side vision, you should see your ophthalmologist.

But physical symptoms aside, Degenerative Vitreous Syndrome can have severe psychological and quality of life implications. Sufferers cite practical difficulties, strains on relationships, negative impacts on work, studies, finances, driving and general enjoyment of life as well as depression and anxiety. It therefore cannot be characterised as a benign condition.
