Posterior vitreous detachment (PVD) is an ocular condition that occurs when the vitreous, the clear gel filling the interior of the eye, separates from the retina, the light-sensitive layer located at the back of the eye.

What Causes This Condition?

PVD is more common in individuals over 50 years of age, as the vitreous becomes more liquid with age and may naturally detach from the retina. Other factors that can increase the risk of PVD include:

  • High myopia
  • Previous eye surgery
  • Ocular trauma
  • Diabetes
  • Hypertension

Symptoms of PVD

The symptoms of PVD can vary from person to person, but the most common include:

  • Floaters: Small dark spots or threads that float in vision.
  • Flashes of light: A sensation of seeing lights or lightning in vision.
  • Blurred or distorted vision: Difficulty seeing clearly.
  • Loss of peripheral vision: Difficulty seeing the edges of the visual field.

 

Treatment of Posterior Vitreous Detachment

In most cases, PVD does not require specific treatment, as symptoms usually improve over time. However, it is crucial to follow medical recommendations to ensure proper recovery and prevent complications.

Nevertheless, if a tear in the retina occurs during posterior vitreous detachment, surgical or laser intervention may be required to repair the injury and prevent a complete retinal detachment. This may include:

  • Cryotherapy: Freezing to seal the tears.
  • Laser photocoagulation: Using a laser to repair the retinal tear.
  • Vitrectomy: In more severe cases, to remove the vitreous gel and prevent further damage.
