PVD: Pvd: posterior vitreous detachment. The gel inside your eyes, vitreous, has partially liquefied, pulls away from the retina which lines the back of your eye. This is a normal with aging. This causes floaters. The only concern is if it begins to pull on the retina ; tears it. Retinal tears can lead to retinal detachment ; blindness. Go to your doctor immediately if you have symptoms.
