If the vitreous is firmly attached to the retina when it pulls away, it can tear the retina and create a<unk> . Also, once the vitreous has pulled away from the surface of the retina, some of the fibers can remain on the retinal surface and can contract. This increases tension on the retina and can lead to a<unk> . In either case, the fluid that has replaced the shrunken vitreous can then seep through the<unk>  onto the macula, blurring and distorting central vision.
