What are the causes of posterior vitreous detachment?

Posterior vitreous detachment refers to the connection between the vitreous body and the retina is loose or broken, resulting in separation of the vitreous body from the retina. For this condition, it is generally related to factors such as age, eye trauma, and high myopia.

1. Age increases

with age, the vitreous body gradually becomes liquefied and contracted, and it is easy to separate from the retina.

2. Eye trauma

, such as eye injury caused by a shot, accident, or surgery, may also lead to posterior vitreous detachment.

3. High myopia

For patients with high myopia, posterior vitreous detachment may occur more easily due to variations in the shape of the eye.
