Sometimes, the retina may be torn as the vitreous shrinks and pulls away from the retina. A tear through a small blocked vessel in the retina may cause bleeding. Clotted blood and vitreous material may appear as a new set of floaters. Retinal tears require immediate medical attention to prevent retinal detachment. If the retina detaches from the back of the eye, partial or total loss of vision may occur.
