Has anyone ever had triple vision?

Opthamologist states he's rarely heard of them but what he does know is they generally come from in back of the brain. They have nothing to do with vision; therefore are not optical migraines. He suggests small TIA's, but not certain and tells me not to get worried about possibly having had a small stroke. Have been taking topiramate for at least 15 years to prevent migraines. So far only a half dozen have 'gotten through'.
