Posterior vitreous detachment (PVD) - causes, symptoms, and treatment
Your eye's vitreous detachment, a translucent fluid, is present throughout. Your eye's shape is maintained by the vitreous. We can still see reasonably well without the vitreous attached to the retina, thus this is essential. The vitreous loses its shape, shifts away from the retina, and compresses inward toward the center of the eye when it becomes overly soft. PVD often and naturally occurs. Your vision won't be lost, and in most cases, no therapy is required.
causes for PVD?
Age is the main cause of PVD. As you become older, the vitreous has a harder time maintaining its initial shape. The distance between your lens and retina doesn't change, but the vitreous gel thins out and takes on a more liquid-like quality.
Although it can happen earlier, PVD mostly affects persons beyond the age of 60. People under the age of 40 are less prone to experience it.
PVD typically impacts both eyes. You may experience a vitreous detachment in your right eye if you already have one on your left.
