Floaters are shapes people can see drifting across their vision. Their exact form is variable - they often appear as small dots or irregularly shaped strands. I f severe Floaters cloud the vision or cause loss of vision. They occur when the vitreous (the jelly-like substance that fills the eye) ages and strands of a protein called collagen become visible within it. These strands swirl gently when the eye moves, giving rise to the perception of Floaters. In some people, usually over the age of 40, the vitreous can separate from the retina. When this happens it tugs on the retina, causing the eye to see flashes of bright white light. A sudden increase (shower) of floaters is usually seen at the same time. This is called posterior vitreous detachment and may lead to retinal detachment..
Are floaters serious?
Generally people should not be concerned about seeing one or two floaters in their vision, particularly if they have been there for some time. A sudden increase in the number of floaters, particularly if also seen with white flashing lights, is a symptom of posterior vitreous detachment. If you see this you should see an eye doctor urgently to ensure you are not suffering from a retinal detachment.

Can floaters be removed? It is technically possible to remove floaters by performing an operation to remove the vitreous - a vitrectomy. This operation carries significant risks to sight due to possible complications, including retinal detachment and cataract. Most eye surgeons are reluctant to recommend this surgery unless there is a threat to sight.
