Posterior vitreous detachment
What is a Posterior vitreous detachment?
Posterior vitreous detachment (PVD), while causing some unpleasant symptoms, does not normally result in sight loss. With age, the eye’s shape changes and the transparent vitreous gel filling the eye loses its rigidity. As a result the vitreous slowly moves forwards, away from the retina at the back of the eye.
There is currently no treatment for PVD, however it is important to have your eyes examined to check for more serious conditions.
If PVD is confirmed, it is usually just a matter of time before symptoms improve. Symptoms can last anywhere from a few weeks to a year but they usually settle after around six months. If it takes longer than six months it is not an indication of a problem, but if concerned, a follow up appointment is recommended.
PVD alone does not cause any loss of vision. In fact, the brain learns to ignore flashers/floaters over time and vision in most cases returns to normal.
