Posterior Vitreous Detachment (PVD) is a common condition occurring as we age. Symptoms like floaters and flashes warrant attention to ensure eye health.
Posterior Vitreous Detachment (PVD) is a common condition that occurs when the gel-like substance in your eye, known as the vitreous humor, gradually shrinks and pulls away from the retina. This natural process happens as we age and is similar to how our hair turns gray over time. While PVD is usually harmless, it deserves attention since its symptoms—like floaters and flashes—can feel unsettling.
Inside every eye, there is a gel called the vitreous humor. This clear, jelly-like substance fills the majority of the eyeball and plays an essential role in maintaining the eye’s shape. Over many years, the vitreous humor undergoes a gradual change, becoming more liquefied and condensing as you age. When enough of the attachments between the vitreous and the retina break, the gel starts to pull away, leading to what we call Posterior Vitreous Detachment.
Though the process may sound dramatic, for most patients it is a natural part of aging. The separation usually isn’t sight-threatening, and the brain adapts to the change with time. However, the process can sometimes cause symptoms like floaters or flashes of light—phenomena that, while typical, should be monitored carefully.
One of the reasons patients might worry about PVD is the appearance of unexpected visual disturbances. Here’s what you might notice if you’re experiencing PVD:
Here’s the thing: although most cases of PVD cause only minor disturbances, maintaining awareness of your symptoms helps ensure that any developing complications are caught early. It’s that small step of paying attention that can make a big difference.

PVD develops gradually as part of the natural aging process. The vitreous humor, which fills your eye, is made mostly of water mixed with proteins and collagen fibers. Over time, this gel gradually liquefies in a process known as vitreous syneresis. When enough of this liquefaction occurs, the gel shrinks and will no longer fill the entire volume of the eye’s vitreous cavity, which remains constant from adulthood onward.
This shrinking process creates a situation where the vitreous humor pulls away from the retina—the light-sensitive layer at the back of your eye. As the gel detaches, clear vitreous fluid gradually fills the space between the condensed vitreous and the retina. In most instances, if the separation happens gently and uniformly, the symptoms remain mild. However, if the separation is too forceful or if the vitreous is abnormally attached in areas such as where lattice degeneration is present, the force can create a small tear in the retina or even lead to complications.
Thus, while PVD is part of normal aging, the balance between gentle detachment and more forceful separation is key to preventing complications. By understanding this process, you can better appreciate why monitoring your vision changes is essential.
While PVD is almost considered a natural milestone in the process of aging, certain factors can make it occur earlier or increase the likelihood of experiencing more pronounced symptoms. Although most people notice PVD after turning 50, there are other reasons why someone might be more susceptible.
If you experience PVD in one eye, it is not uncommon for the other eye to be affected within a few years. Keeping track of these risk factors can be a helpful guide in scheduling regular check-ups with our eye doctors.
