Today around 2pm I was watching television when my vision in my left eye became blurred with a blurry curvy line of white running around the outer rim of my vision in the left eye. It was enough that it was very bothersome and a bit frightening. I called my husband at work to take me to the hospital it got so bad. Anyway went to the ER and had multiple tests ran and still no answer. The blurring finally went away also. I had bloodwork, lab work, a ct scan also to rule out a stroke because not only is that a symptom strokes run in my family. I think maybe my blood sugar went up high for a short time and caused it. My blood sugar was only 186 at the ER which is high but not high enough normally to cause this sort of problem so I have to make some eye appointments now. Anyone else have blurred vision with FM?
