Dear doctors, Please answer my query. Can lightening streak type flashing persist for 10-15 minutes. And does it throb and sometimes look a little colourful also?? Is it associated with slight headache within 30 minutes too. What if it happens every month in one month interval. Does it have big zigzag pattern and is a little wide and have borders. Can it be seen by both eyes at once for 15 minutes straight? I have attached a picture of what I believe I might have seen for 10-15 minutes post which I had a mild throbbing headache too. But in my case it had not been that bright. I have dry eyes and -2 myopic with which I have also recently developed a couple of shadowy floaters.
