Posterior Vitreous Detachment
A vitreous gel change that can cause floaters or flashes, often needing assessment when new.
What is it?
Posterior vitreous detachment (PVD) is the natural separation of the vitreous gel from the retina as the eye ages. It commonly causes a sudden increase in floaters or flashes, which usually settle over weeks.
Common symptoms
- Sudden onset of new floaters
- Flashes of light
- Cobweb-like shapes in vision
Risk factors
- Age over 50
- High myopia
- Previous eye inflammation
- Eye trauma
Prevention tips
- Attend regular eye examinations, especially with increasing age or high myopia
- Seek urgent ophthalmic care for new flashes, a sudden increase in floaters, or a curtain-like shadow in the vision
- Protect the eyes from injury during high-risk activities
- Maintain regular follow-up if you have had retinal tears or detachment in the other eye
- Follow postoperative instructions carefully after eye surgery
Treatment overview
No treatment is required for uncomplicated PVD. Patients should be warned about symptoms of retinal tear (sudden shower of floaters or flashes with a shadow) and return urgently if these develop.
Seek urgent care if you notice
- Sudden increase in floaters
- New flashes of light
