Condition
Posterior Vitreous Detachment (PVD / Vitreous Separation)
Posterior Vitreous Detachment (PVD, or vitreous separation) happens when the clear jelly inside your eye (vitreous humor) shrinks and pulls away from the retina. This is common with age and usually harmless, but sometimes it can cause flashes or floaters.
