Specks of optical debris in the vitreous humor that drift across the line of vision and seem to dart away when a person attempts to look directly at them. These threads or cobweb-like clusters of dead cells or fibrils are caused by a slowly shrinking vitreous. Floaters can be bothersome or irritating but can be ignored unless they become numerous and more prominent. They can lead to uveitis, retinal tears, eye injury, or inflammation.
