Flashes and Floaters

Flashes of light along with floaters are symptoms of vitreous detachment and possible retinal detachment, a condition in which the vision sensitive film of the eye pulls away from the eyeball. The vitreous is the jelly-like substance in the eye that holds the eye together and gives the eye its shape. Floaters occurs when the vitreous is pulled away from the retina and floats within the line of sight, casting a shadow onto the retina. Floaters by themselves are harmless. However, floaters occuring concurrently with flashes are signs of possible retinal detachment,if left untreated can result in permanent vision loss or blind spots.
