The vitreous gel occupies the entire back portion of the eyeball. With age, the vitreous gel begins to liquefy and pull away from the retina. A PVD occurs when the gel and the retina have completely separated. PVD is a natural change that occurs with age, and happen in over 75% of those aged 65 or over. It is important to remember that PVD i not an ocular disease nor is it a sign of any impending eye health issue unless it occurs at a relatively young age.
The most common symptoms of PVD are flashing lights and floaters.
For most people, no treatment is required. The detached vitreous remains detached and does not re-attach again. PVD does no cause any permanent vision loss, but some associated complications may affec the vision. It is therefore very important that you consult your ophthalmologist as early as possible for a thorough dilated retinal examination if you experience th symptoms of flashes and floaters.
In most cases, PVDs occur without causing any problems. However, in up to 10% of cases, PVDs are accompanied by an ocular complication. These can include vitreous hemorrhages, retinal tears, and retinal detachments.
