I have been experiencing Ocular Migraines for over 10 years. (I am a 53 year old male). I get both the "shooting stars" and I sometimes get the expanding zigzag image. The shooting stars (or flashes as some folks refer to them) come mostly when I am at work during stressful situations and the zigzag images happen at any time, even during the night when I am sleeping. I do sometimes get painful headaches but they don't always coincide with the ocular disturbances. I normally get the headaches late in the afternoon on days when I am at work. My question is what your opinion is about how much this raises my chances of having a stroke or heart attack? My blood pressure is normally good, but I am on a cholesterol lowering drug (20 MG of Simavastin). Experiencing these auras is unsettling enough but hearing about the possibility of an increased risk of stroke really causes me to be very concerned. I thank you for your time and I look forward to your response.
