Flickering in eye - optical migrane?

[TineBiene7]

About once a week, I have a vision disturbance, which starts as a tiny flickering dot that gets larger and larger and turns into an irregular type of circle.  The edges of the semi-circle are like jagged "saw-type" sharp edges in brilliant colors. At first it seemed that I was seeing this in both eyes, but recently I have been able to pin it down to my left eye only. When I close my eyes I can still see the visual disturbance, only the colors are more vibrant. The semi-circle gets larger and larger until it is out of my peripheral vision, which takes about 15 to 20 minutes.  During this episode, I am unable to focus on anything (can

I have the exact same effect, it is really beautiful and scary at the same time, the geometric shapes are amazing, I suspect that it is an interrupted visual signal that is trying to reach the brain or something like that.  I had about 10 of those in 6 months, they stopped for awhile an now they seem to be back, I just 2 today, which is very rare for me, I normally was getting like 1 a week.  So I am trying to figure out what is triggering them like everybody here on the forum.  I had intense gym workout this weekend and right after I had those optical migranes, I wonder if it is muscle related or some kind of chemical that brain releases that is muscle related.  

I also spend 8-10 hrs on computer so maybe thats the trigger, but then again, I didnt have those for 1 months and now for no reason they are back again, I am really worried now.

I have actually had a few of these episodes myself. The first one that I had was so bad the dr rushed me to the er thinking I had a anerisum however you spell it. But the er said I had opticular migraines. I have had a couple of these over the past year. I am not sure about all the information with them. I just know that my sight is affected, it feels like im looking at the sun and looking away but the glow or light is still in my eyes, even when i close them. and i get dizzy or well it just makes me feel wrong when i go through this.

I am a 66 year old retired male (diabetic) who spent the last 25 working years on a computer but have been retired for 4 years.  Two weeks ago I started having optical migraines in my left eye, in fact I had 5 the first day.  I lost total vision in one eye each time.  Very scary.
I have been to my eye doctor (an MD) and then  a neurologist. I have had blood tests and also have had sonograms done on the arteries in the neck and the heart.  A  MRI and MR-A done  on the head and am scheduled to see an optical neurologist at his earliest convenience.  Mine have been triggered by a sneeze of a cough, have happened while laying down in a dark room and the last one was as I typed the first line of this note. I have come through all the tests clean with two exceptions,  my blood sugar, which has been in line for years is now gone up.   My last a1C was 5.7 and six months before it was 5.6. (For you non diabetics out there that is exceptional)  Now out of the blue after a 12 hour fast my Blood Sugar was 182  And my blood pressure which has always been text book ( 120/80)  has fallen   and was 84/40 . For the time being I am on anti migraine drugs ( nasty stuff that) and waiting .

hi,
I also have this and have for 5 yrs. it looks like your seeing through a colidascope that gets brighter and bigger then statrs to fade ! its scarey
I went to my family Dr. and he even has this and has done tons of research and sent me to the Eye Dr. & found it to be Optical nerve migraine and it starts in the brain, its a small siesure that makes a spasm in the optical nerve and the blood flow and oxigen cant get through to the eye and it gives most a very bad headache after the eyes start to clear up. my last one was really bad lasting for an hour or more till the eyes cleared... so back to the Dr. I went and they put me on anti seisure medication that they said has helped many to never get them again and even children ...so hope it works for me !  Also they said stress can cause them to happen more often.
hope this helps everyone
thanks

I have experienced this about 4 times, and have experienced a pattern. Like many, I went to a doctor and she concluded optical migraine. The pattern always is the same. First, I get an area in my vision that I can no longer see - for instance, if I'm looking at a headline of text, maybe the last few letters are invisible - a small black hole. I first noticed it while watching TV, where I was no longer able to see detail in the center of my field of vision. Then, I kept having the sensation that there was something flickering, and I slowly became more aware of what seemed like a jagged blurry line in my vision, with lots of colors in it, that appeared to be flickering. Even with my eyes closed, I could see the line. I freaked out and started walking home, and within about 10 to 15 minutes, everything was back to normal.

Now I can predict them. I work on the computer a lot, and when I notice the inability to see a small part of whatever I'm looking at, I know it's starting, and sure enough, within about 10 minutes, the flickering line shows up. 10 to 15 minutes later, it is gone, and everything is back to normal.

I wonder what triggers it. Last night I got a tiny bit drunk (I rarely drink, so this is uncommon), so that is the only thing I can pinpoint as a trigger.

I just experianced an optical migrane today. I wasn't sure what it was and it really scared me as it did others. I started to notice bright blurred zig zag lines in the right eye (I'm also right handed so don't think this has anything to do with it). It lasted not longer than 20 mins, but I did go to the emergency room just to be on the safe side since I didn't know what it was at the time. They too told me it was an optical migrane. The information they gave me was that they are very rare, people who get headaches often get them and they last about 15-20 mins. He did mention if I started to get them more frequent to go see a neurologist but feels that wasn't necessary now since this was my first one.
