Posterior vitreous detachment (PVD) is very common and most people will develop it at some point in their lifetime.  Some symptoms may include floaters, small flashes of light or a cobweb in your vision. These symptoms are very similar to those of a retinal detachment, so it’s important for you to have your eyes checked as soon as possible by an Optometrist or Ophthalmologist so they can determine what the cause is.    The retina is a delicate tissue coating the inside of the eye.  When we look at something, light passes through the front of the eye, and is focused by the lens onto the retina.  It changes the light into electrical signals that travel along the optic nerve to the brain.  The eye is filled with a clear jelly-like substance called the vitreous gel. This gel also helps the eye maintain its round shape. Light passes through it to focus on the retina.  When the vitreous jelly comes away from the retina this is called a vitreous detachment.    Most of the time, no treatment is recommended.  On rare occasions, a surgical procedure called a vitrectomy may be needed to remove dense floaters that significantly affect your vision.
