I took a blow to eye 12 days ago. I have had my eyes examined twice since, with no retinal problems reported or any sign of anything to worry about from the docs. I still see flashes when i move my eye back and forth. they are always in the same spot. they resemble the spots you see when you look into the sun and look away. i heard the doc say to the nurse that it was photopsias. what is causing these spots, and when should they start to disappear? are they the rods and cones, or something tugging at the retina? i have been given the signs of worry for a retinal tear or detachment, but none of those symptoms have occurred as of yet.
