Can a PVD Cause Vision Loss?

For most people, a PVD is a benign (harmless) event with no symptoms and no vision loss. Others may notice a lot of floaters. Floaters can be bothersome but usually become less noticeable over time.
For a small amount of people having a PVD, problems occur when the vitreous detaches from the retina. The vitreous pulls too hard from the back of the eye and takes a piece of the underlying tissue (the retina) with it. This is called a retinal tear. It can lead to a retinal detachment, which can cause permanent loss of vision.
If I think I’m having a PVD, what should I do?
Most people don’t know they are having a PVD. But if you notice a lot of floaters or flashes of light suddenly, or have a decrease in vision, see your ophthalmologist as soon as possible. These symptoms can be normal, but they can also mean that you have a retinal tear or retinal detachment. You won’t be able to tell the difference but an ophthalmologist can. If a retinal tear or retinal detachment is treated early enough by an ophthalmologist, you can save your vision.
How is PVD treated?
If a PVD happens normally without any damage to the retina, no treatment is needed. If a retinal tear happens during a PVD, treatment is usually needed. Your ophthalmologist will seal the retina to the wall of the eye using a laser or cryopexy (freezing treatment).
