Posterior Vitreous Detachment

Vitreous is a gel-like substance that fills the inside of your eye and attaches to the retina (the back of the eye). It is normal for this vitreous to shrink as you age, causing the millions of tiny fibers inside the vitreous to pull on the retina. If the vitreous pulls away from the retina, this is called a posterior vitreous detachment. This is a common condition in people over age 50, especially if you are nearsighted. 

Symptoms of Posterior Vitreous Detachment

There are often no symptoms of a posterior vitreous detachment and it may not affect your vision. However, some people do experience symptoms such as: 

  • Flashes of light in your peripheral vision
  • Floaters that look like cobwebs or dark spots in your vision
  • Shadows that dart around your vision

Side Effects of Posterior Vitreous Detachment

A posterior vitreous detachment may not threaten your vision. However, it is possible for this condition to lead to a tear in your retina, retinal detachment or a pucker or hole in your macula (the center of your retina). Any of these conditions will threaten your sight and must be treated immediately. If you experience any of the above symptoms, we recommend you schedule an eye exam right away, just to be on the safe side.  

Treatment for Posterior Vitreous Detachment

Your doctor will want to perform regular dilated eye exams to monitor the posterior vitreous detachment and ensure that there is no serious retinal damage. While treatment may not be necessary for a posterior vitreous detachment, your doctor will definitely treat any new condition that develops such as a retinal detachment, macular hole, etc. Our retina specialists in Eugene, OR, may recommend laser surgery, cryotherapy (freezing), vitrectomy or another treatment.
