Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.

Expert:  Dr. David replied 1 month ago.

yes, it is possible for a clot or plaque to break off in your carotid artery and spread to the brain to cause a stroke and damage part of the brain and cause hemianopsia or decreased vision or blindness in half the visual field

did this happen to you?

did you have a brain MRI scan to look for signs of stroke brain damage?

I had a vascular surgeon tell me that my hemianopsia was caused by clot breaking off of plaque built up in my carotid artery and a neurologist tell me that that wasn't possible because the occipital lobe is not supplied by the carotid arteries.

there is the circle of willis in your brain where clots from your carotid artery can get to the occipital lobe of your brain.
