I had a routine eye exam and was told the optic nerve in my right eye was swollen. I was refered to a retna specialist and upon seeing him discovered I had some visual field loss. I was ordered to go for an MRI witch I have not yet recivied. I also have been having nausea and vomiting and a very intense headache for a few weeks now witch I have been to the ER twice for. The nausea and headache all started a week before I found out about the optic nerve and have not been confirmed if they are related. Can anyone tell me what could be causing my optic nerve to swell? Is the nausea and headache connected? When I asked the specialist he said prolly but wouldn't say for sure. If they are connected what could be wrong with me? Any one with similar experiences/stories? Thanks in advance.
