'ring of fire' in vision

[imdvdim]

Does anyone know of, or have heard of a condition, I can best describe as a circular expanding prismatic (sparkling) condition in my vision that is not characteristic to one eye. But, always to be in both vision fields in exact same spot, whether eyes closed or open. Starts as a small spot a few degrees off of center of sight and, always expands for over approx., and hour to a large symmetrical  sem- circular sparkling ring in my sight, always off of center. And can be to the either left or right. But, never full circle.. To eventually going away... Please answer if any ideas or responds to this. It has occured to my sight only at about the rate of once or twice a year for the past 5 years.. But, curiously twice in the past week..

sounds exactly like a migraine.  There are pictures of this on wikipedia under migraine.

Use the search feature here and look up "eye migraines and ophthalmic migraine"  also TIA.  Go to google IMAGES and type those words in to see what they look like

You need to see an eye MD as in some cases the prisms can be caused by disease of the eye, brain, heart or blood vessels.  Given how infrequently yours occurs you are 95% plus have rare ophthalmic migraine.

Tell your MD and your Eye MD about these.
