Hey, Tkrik (are you Natalie?) you were right! The eye doctor said she had had a migraine similar to this, only one in her life (and this one was my first), and that this is the latest viewpoint about what a migraine is, that it is a neuro storm or seizure.
She said to go ahead with the ultra-sound today, which I did, and no clot was discovered. My eyes have been normal since the occasion and I am going to be more careful about studying fine-print records as I had done that day.
I would not report the doctor. Having a rare disease, porphyria, I know that I will receive aberrant behavior and opinion from doctors who do not understand the situation. It is part of the territory. I talked to a couple of people about it, though, and they said this doctor was considered a misery by several people who have gone to the ER. Usually I get very good doctors when I've gone there in the past. It's rolling the old dice.
My eyes have been OK since then!
