ocular migraine?

Hi i was just wondering if anyone out there experiances ocular migraines? It happened to me last night and really freaked me out.. so bad that I went to the emergency room. No pain or anything just strange vision. I tend to panic over these things. At the ER they told me it was because of the hormonal changes due to my pregnancy... I was wondering if that's possible... and i was wondering if anyone out there gets them how they deal with them?

I have ocular migraines and it is like a C shaped lightning bolt with a bright light in the bolt. It starts out small and expands beyond my vision. I just sit down and wait it out usually about 30 to 45 minutes. Even with your eyes closed you can still see it. It is dark and has a brigh light within the bolt. I don't usually have any pain with it. Since August I have started having full blown migraines again. I had them after my hysterectomy in my 30s and they went away. I am now 58 and they are saying I have vasculitis. I have brain lesions in the periventricular, deep white matter and subcortical regions of the brain. I have had 5 migraines and ended up in the ER the last two. I took a vicodin but couldn't get them to ease off and went to the ER and got an injection after they did CT scans etc. I cannot take anything to abort them because I have atrial fib, mitral valve prolapse with regurgitation, and patent foramen ovale, (heart conditions that preclude preventive type meds). Hope this helps. I wish you much luck and hope your pregnancy continues on a healthy regimen.

I believe I had my first ocular migraine today. I was at work and coming back to the office. I felt a sharp pain in the side of my head, I didn't think any thing of it. Then I saw zigzag colorful shapes in my left eye. They were disturbing my sight. I kept blinking thinking they would go away. My boss told me it could be retinal detachment and made me call my eye doctor. They put me on hold for a long time and by then it had stopped so I hung up!! It was a very odd sensation.
