causes of floaters in eyes
Most eye floaters are caused by age-related changes to the jelly-like substance (vitreous) inside your eyes. As the vitreous becomes more liquid, its microscopic fibers clump together and cast tiny shadows on the retina, which appear as floaters. Several medical conditions can also cause floaters.
When this occurs, accumulation of shredded collagen sometimes causes the vitreous humor, or gel, to move away from the retina, resulting in floaters. Eye disorders and diseases occasionally associated with floaters include retinal detachment, retinal tear, vitreous hemmorhage, retinal inflammation and eye tumors.
