Every once in a while (usually spaced at least a few months apart) I'll suddenly notice a small blurry speck in front of my eyes. The speck will gradually grow, becoming a clear semi-circle with vibrating, rainbow-colored crystalline edges. Within about 20-30 minutes, the speck will grow from being in front of my eyes to going all the way to the edge of my vision, then disappearing. This is rather disconcerting, and I have to stop what I'm doing and just shut my eyes while it's happening because I can't see anything clearly enough to work. After it is gone my vision still feels abnormal and "fuzzy," especially in my peripheral vision, for a while, and my head will ache dully (but it's not super-painful or anything). Is this anything I need to be concerned about? Is there a name for this? Thank you for any information you can give me.
I came across this article while searching for these exact symptoms. I realize this is 4.5 years old, but in case anyone else comes across this page please look up "Ocular Migraine." I was quite concerned when this happened to me 5 times in 2 months, and Googling the symptoms wasn't getting me anywhere. After calling my eye doctor, she told me it sounded like an Ocular Migraine. Sure enough, when I looked it up that was exactly what was happening to me. I made an appointment to get checked out anyway, just in case, but at least knowing what it is helped to ease my fears.
I have experience this in this same pulsing concentric circles about five ties in the past few months. The eye doctors at at a well known state teaching college didn't know what it was. They said it sounded like it was associated with migraine although I had no pain. Went to the neurologist today. The neurologist said it was not a migraine associated Aura, they do not display as such. Said it sounds like blood flow. I'm worried and confused as to who or what I should do. I've been feeling lightheaded with feeling of passing out. Was even sent to the ER from work. But my doctors say my blood pressure is fine. Any suggestions? I really would like an answer. Thanks!
