Every couple of years since I was a kid I get geometric patterns of lines flashing black a white and sometimes in different colors. It starts off in a small spot to the right of my visions and over about an hour it progress to cover about half of my vision, and then abruptly disappears. I won't see it again for a year or two.
I can't tell what eye it’s in because if close either eye I can still see it in the others view.
It doesn’t hurt and I don't get a headache or nausea.
Hello dwod, Nancy T is exactly right. You have symptoms of classical ophthalmic migraine. You can use the search feature on this website. Lots of postings about ophthalmic or optic or eye migraine. You can also use the Google Image search feature and search the same term. It will have multiple pictures of the various forms of "scintillating scotoma".
Nevertheless inform any physician you of having ophthalmic migraine. If you are female it may have a bearing on using oral estrogens. It very important that you not smoke as migraine in its many forms in smokers and to a lesser degree with high blood pressure or high cholesterol has higher rates of strokes.
If something changes, these get worse, new symptoms appear you need to see ophthalmologist and a neurologist.
