WebPosterior vitreous detachment (PVD) occurs when the gel that fills the eyeball separates from the retina. It’s a natural, normal part of aging. PVD can cause floaters or flashes in your sight, which usually become less noticeable over time. The condition isn’t painful, and it doesn’t cause vision loss on its own.
