Posterior Vitreous Detachments, or floaters, occur as a natural part of aging. They can also occur earlier in life if you are nearsighted or have blunt trauma to an eye or head. Initially the floater may appear as a black dot or tadpole in your vision. A dilated eye examination should be performed to check the entire retina to insure there is not a retinal hole or a retinal tear. Failure to diagnose a retinal tear and treat it early can lead to a retinal detachment and a bigger surgery.
