Posterior Vitreous Detachment

As we get older, our viterous (clear substance that fills the inside of the eye) starts to shrink and thicken. If the viterous pulls away from the back of the eye, it is called Posterior Viterous Detachment. Floaters (small specks, dots, circles, or lines in your field of vision) or flashes (flashing lights or lightning streaks in your field of vision) usually occur with this disorder. 

Floaters and flashes are common as people age and are not serious. They tend to fade or go away over time. Usually, a patient will not need treatment or surgery.
