What is a posterior vitreous detachment?
The vitreous is a clear gel that fills the cavity of the eye. As part of the normal ageing process the vitreous may pull away from the back of the eye (retina), and collapse into itself.
What are the symptoms of posterior vitreous detachment?
Some patients notice floaters (small spots or shapes that float in your vision) and flashes of lights. If these occur you should be examined by your optician, or Professor Jackson, within a day or two, to rule out more serious problems. A few longstanding floaters are often normal, but nonetheless warrant routine review.
Posterior vitreous detachment can sometimes be associated with retinal tears and retinal detachment.
Do I need treatment?
Usually not. The floaters do not cause any harm and tend to subside with time. If they persist and are very troublesome Professor Jackson can discuss removing them with surgery or laser treatment, but usually they are best left alone.
Further information about floaters and posterior vitreous detachment can be found in the patient information leaflet.
