Posterior Vitreous Detachment (PVD)

Posterior vitreous detachments (PVD) occur when the vitreous — the clear, gel-like substance filling the middle of the eye — naturally shrinks and separates from the retina. This is a common age-related change and is usually harmless, but in some cases, it can lead to complications if the retina is pulled or torn during the process.

A PVD usually causes symptoms such as floaters or flashes of light that should be promptly assessed to rule out retinal tears or detachment. Early evaluation by an eye specialist is important to protect vision and manage any associated risks.
