PVD is a common degenerative change, which affects one or both eyes in many people after middle age. It may present earlier in shortsighted patients or those who have sustained traumas to the eyes.
Thickening of the jelly casts shadows on the retina and are seen as floating shapes. These black “floaters”in your vision move with the eye and then settle as the eye rests. These are often described by patients as a “cobweb” or “insects”.
You may also be aware of flashing lights, like little flickers in the outer periphery. Usually these do not highlight a problem, however, it is important to have the eye thoroughly checked, as occasionally a retinal tear or a retinal detachment may occur.
