What causes posterior vitreous detachment?

Posterior vitreous detachment is caused by the normal shrinking of the vitreous, a gel-like substance in the eye that is attached to the retina in the back of your eye. Over time, microscopic fibrils collapse, the vitreous shrinks and may eventually pull away from the retina. This separation from the retina is termed posterior vitreous detachment or, more simply, vitreous detachment.

In addition to occurring as a result of normal aging, vitreous detachment may be caused by surgical procedures in the eye such as cataract surgery, by eye injury, or by severe head trauma.

What are the risk factors for posterior vitreous detachment?

A number of factors increase the risk of developing posterior vitreous detachment. Not all people with risk factors will get posterior vitreous detachment. Risk factors for posterior vitreous detachment include:

  • Age over 50 years
  • Nearsightedness
  • Vitreous detachment in the other eye
  • Vitreous hemorrhage
  • Vitreous inflammation
