What Causes Floaters?

The appearance of floaters may cause much concern, especially if they develop suddenly. However, floaters are usually a result of the aging process. As we mature, the vitreous gel shrinks and pulls away from the retina. Floaters are formed from the reorganization of the vitreous material and from some fragments of the retina which have been pulled into the vitreous cavity.

Floaters are especially common in nearsighted people, in people who have suffered eye injuries, and after eye surgery. Although uncommon, floaters can also result from inflammation within the eye or from crystal-like deposits which form in the vitreous gel.
