Yesterday I was standing at a conference and suddenly my left eye was causing crossed vision. This has never happened before. I was diagnosed with low pressure glaucoma but am not taking medication for it. When I covered my left eye, the crossed vision was no longer and when I removed my hand it returned. This lasted for only a couple of minutes and I was fine after. I am a 59 year old firefighter and the first thought that entered my mind was STROKE. This scared the daylights out of me so I am just not sure.
