Background

  • Separation of posterior vitreous from the retina, as a result of vitreous degeneration

and shrinkage

  • Age-related event (prevalence):
    • 50-59 yrs = 24%
    • 80-90 yrs = 87
  • Risk factors
    • myopia
    • trauma
    • intraocular inflammation
  • in the majority of cases PVD is benign
  • in acute phase, concern is for causing retinal tear, which can lead to retinal detachment
  • Prompt diagnosis and surgical treatment of retinal detachment can prevent impending

vision loss or can restore vision
