Posterior Vitreous Detachment Q & A

What is vitreous?

The vitreous is a clear, gel-like substance inside your eyes between the lens and retina. It’s firm enough to exert the pressure needed to maintain the shape of your eye and to ensure layers of the retina stay pressed together. It also helps transmit light to the retina by keeping the center of the eye clear.

What is posterior vitreous detachment?

The vitreous doesn’t just freely float around in your eye. Millions of thin collagenous fibers weave through the vitreous gel then firmly attach to the retina’s surface.

Over time, the vitreous becomes more liquefied. As a result, the gel shrinks, pulling on the fibers attached to the retina. If the fibers break, the vitreous separates from the retina, causing posterior vitreous detachment.

Are you at risk of posterior vitreous detachment?

Vitreous detachment is a common occurrence that affects people aged 50 and older. Your risk increases after the age of 80. It also occurs more often in people who are nearsighted.

If you have a vitreous detachment in one eye, your chances are higher for having it develop in your other eye.

What are the symptoms of posterior vitreous detachment?

You may not have any symptoms when the vitreous detaches, but if you do, you’ll experience an increase in floaters, flashes of light, or both. Flashes of light occur in about half of all patients, but floaters are the most common symptom.

You see noticeably more floaters because tiny pieces of tissues are torn from the retina when the vitreous detaches. These opaque substances get stuck in the vitreous and cast shadows on the retina, which you perceive as floaters. The floaters may diminish over time, but you still have a detached vitreous.

Does a detached vitreous affect your vision?

A vitreous detachment doesn’t harm your vision. When it detaches, however, it can pull hard enough to detach or tear the retina; both are serious conditions that cause permanent vision loss.

How is a posterior vitreous detachment treated?

If you don’t have any symptoms, Dr. Abdelghani may recommend more frequent eye exams to watch for signs of a retinal tear. If your retina is torn or detached, surgical intervention is essential to prevent vision loss.
