What Is a Posterior Vitreous Detachment?
2. Causes
The main cause of posterior vitreous detachment is age. The ageing process affects the vitreous body in a way that causes it to lose its shape. The gel in the vitreous body will become more fluid, and the vitreous body can shrink overall. Despite this, the eye itself will remain the same size.
The vitreous body will still remain in position for a while as it is helped in place by microfibers, until it shrinks too much. Posterior vitreous detachments usually happen in people at around 60 years or older. It can happen in younger people, but it is not common in people under the age of 40.
