Hi All,
About once a month I have a problem with my eyes, or probably the nerves controlling my eyesight. I see something like an oval mark that is drawn up and down in a half circle. It sometimes keeps me from seeing properly, depending where it is. I just can't see directly through it. I asked my doctor and he said it was something that usually goes with a migrane headache. I don't have any pain, thank goodness and it usually goes away in about 10 minutes. I can see it with my eyes closed or open and it seems to pulsate. Has anyone heard of this before? It's happening right now but it is to the left of my eyesight so I can see straight ahead OK. It's really no problem but I wonder what causes it.
