About 10 years ago I went to an ophthalmologist. I had experienced a situation which I can only describe as a visual phenomenon traveling from one part of my visual field to beneath it. I was partially blind because of it. I can only think it was a very small stroke or something. They found nothing wrong with my eyes and in passing I mentioned these white things.
Combined with my inability to explain what I saw, the doctor was visibly annoyed and said I need a psychiatrist not an ophthalmologist.
Over what time frame what the phenomenon? Have you heard of migraine aura? Descriptions vary, but they typically involve a visual disruption traveling across your field of view. They aren't always followed by headaches, and I have trouble seeing when I get one.
