What is PVD?
Posterior Vitreous Detachment (PVD) occurs when the clear, gel-like vitreous inside your eye naturally pulls away from the retina. It’s a normal change that becomes more common after the age of 40, especially in people who are short-sighted. In most cases, it’s harmless and doesn’t require treatment.
The risk is that, in some people, this separation tugs on the retina strongly enough to cause a tear. A retinal tear can rapidly lead to a detachment, a sight-threatening emergency. Around 1 in 10 people with acute PVD have a retinal tear, which usually needs prompt laser treatment to prevent further damage.
That’s why if you suddenly see new floaters, bright flashes of light, or a shadow moving across your vision, it’s important to have your eyes examined without delay.
Common symptoms of PVD
These can appear in one eye or both. Even if symptoms seem mild, a retinal tear can develop quickly, which should be treated as soon as possible.
Sudden new floaters (black spots, cobwebs, or threads in your vision)
Flashes of light, especially in dim conditions
A shadow or “curtain” moving across your vision (urgent red flag)
Sudden drop in vision clarity
What to do right now
- Noticing a shadow, curtain, or a sudden increase in floaters? Get in touch promptly or visit a specialist clinic.
- First episode of flashes or floaters? Arrange an assessment as soon as you can, ideally the same day.
- Changes after a recent check-up? Come back for a review. Retinal tears can develop shortly after PVD starts.
