What are floaters?

After middle age, many people see small dark shapes described as “cobwebs”,” strings” “insects” “rings” or “spots” that appear to float in their field of vision. These may appear intermittently or be permanent. These are termed “floaters”. Floaters become visible by casting shadows on the retina. With age the vitreous body liquefies and small particles of vitreous break away and float in this liquefied vitreous. Some floaters can be removed or treated with laser, this is called Yag Vitreolysis.
