Your eye’s vitreous detachment, a translucent fluid, is present throughout. Your eye’s shape is maintained by the vitreous. We can still see reasonably well without the vitreous attached to the retina, thus this is essential. The vitreous loses its shape, shifts away from the retina, and compresses inward toward the center of the eye when it becomes overly soft. PVD often and naturally occurs. Your vision won’t be lost, and in most cases, no therapy is required.

Risk factors for early PVD include:

  • cataracts
  • eye operations
  • diabetes
  • A visual injury
  • nearsightedness

Symptoms of PVD?

PVD does not cause pain or permanent visual loss, despite the risk of additional symptoms. They are :

  • Flashes. These flashes of light are like the “stars” you get when you bang your head. They usually come to an end or stop altogether when dissociation is complete. They could be brief or lengthy.
  • Floaters. These moving objects in your field of vision could appear as minute particles, spots, dust, or ominous, cobweb-like objects. The simplest way to locate them during the first few weeks of PVD is to stare at a light surface, like the sky or a white wall.
  • Cobweb result. It’s possible to begin noticing the vitreous’ exterior when it begins to separate from the retina. You might experience the sensation of sifting through cobwebs. This only persists to the end of dissociation, after which it disappears.

Causes for PVD?

Age is the main cause of PVD. As you become older, the vitreous has a harder time maintaining its initial shape. The distance between your lens and retina doesn’t change, but the vitreous gel thins out and takes on a more liquid-like quality.

Although it can happen earlier, PVD mostly affects persons beyond the age of 60. People under the age of 40 are less prone to experience it.

PVD typically impacts both eyes. You may experience a vitreous detachment in your right eye if you already have one on your left.

How to treat PVD?

Despite the fact that PVD is a common condition, if you notice any new floaters or flashes, you should see a doctor right away. A PVD or a retinal detachment could bring these on. Your doctor may need to run a diagnostic test in order to figure out what the issue is.

A dilated eye exam can determine whether you have PVD, a retinal detachment, or another eye problem. During the examination, your ophthalmologist or optometrist will insert certain drops into your eyes. These drops cause your pupils to enlarge so that your doctor can see the back of your eyes. Your doctor can then check your entire retina, macula, and optic nerve.

The inspection lasts for about 30 minutes. Before it goes away, the dilatation may persist for a few hours. You should put on a pair of sunglasses after your treatment because the sun and bright lights could be painful.
