My symptoms were a monocular blockage of sight, with translucent transmissions, which I identify as amaurosis fugax. And a zigzag pattern that would develop over my field of vision, called scintillating scotoma. Both have been referred to as optical or ocular migraines, with no headaches. They occurred once a week or so.

These are sometimes signs of blockage of the carotid artery, which can be detected with ultrasound and MRA scans. I had both, and was in surgery the day after, for a carotid endarterectomy -- a reaming out of the artery that delivers blood to the brain.

My surgeon told me I was in line for a major stroke. My artery was almost totally blocked. It's almost four weeks since the surgery, and so far the visuals are gone.

Yes, life is good!
