I’ve had this phenomenon for some years, not sure whether I had it prestroke but have visits from it quite often. It has been explained as a headache which seems realistic. It doesnt interfere with my vision and at its worse is only a nuisance. It gets bigger and bigger and eventually just vanishes. Its impossible to forecast.
This picture is the nearest I can get to describing it.

OK thanks for the info. Mine are similar and quite random. Other than always just after I wake in the morning.

I would get migraine aura about a couple of times a month prior to mild stroke. Found a couple of paracetamol would dsperse them a little quicker.

It’s not until you have this happen that you find out how common it is. I’ve had migraine auras since my mid 20’s and I’m 73 now. They have always varied in frequency and intensity, but each episode is usually over in about 25 minutes. I don’t get headache pain with them and they’ve become more of an incovenience than a worry.
I had my stroke on first of June 2023 and since then I’ve had just one of them. It bothered me when it came on because I wondered if it was going to be worse but it was pretty much the same as all the others I’ve ever had. My ischemic stroke was caused by stenosis of the right carotid and I’ve never heard of that being associated with migraine auras. Actually this latest attack came well after my endarterectomy so it’s unlikey to be connected. There are various theories what they are but the truth is that nobody knows for sure. Mine are usually triggered by bright or flashing lights.

Your graphic is rather interesting @Deigh
I had migraine auras through my 50s not before and not since my stroke.
Mine were zig-zaggy a bit like you have illustrated but always in black and white !
They started as a spot normally near the centre of my vision and elongated into a drifting ribbon that never turned back on itself in the way your c letter shape does. In fact now while I think about it they generally went from top right to bottom left .

Mine also lasted less than half an hour I think generally 20 minutes.

Quite often though we’re co-incident with a reduction of vision right in the centre of my vision. Mine would never accompanied by pain of any sort either.

Thanks for your input. The PC screen seems to be a trigger. Currently mine are decreasing in frequency and duration. None at all yesterday!

Great news, Yes, the PC screen triggered mine last week. I usually reach for the dark glasses until it’s passed.

Hi Simon, The drifting ribbon of flashing jagged lights is also what I get, following on from an intitial blank spot in the centre. Interesting that your flashes come in black and white, mine are always blues, yellows, reds.

That is similar to what happens to me. I describe it as a kaleidoscope. Even when I close my eyes and sit in darkness it is still there.
One of my major triggers is bright sunshine. Sunglasses (polarising) are essential for me on a bright day.

That is always the first thing to happen. a ‘hole’ in my vision, then I know it will be about 5 minutes until it’s full on. . I say ‘Flash Attack’ if my wife is there so she knows what’s happening. Well, actually it usually has an ‘f’ word as a prefix. :grin:

Thats interesting, you had them before your stroke and not since, my experience is the opposite.
the picture I added to my report I downloaded from the internet and is not exactly like the ones I experience, Mine are square multi coloured boxes but I didnt think think the shape mattered, just the fact that the apparition exists.
Incidentally, it’s still there even when I close my eyes!

I agree the shape doesn’t matter in one regard, I wonder whether it is indicative of anything that we don’t understand?. And I would expect that it is there when your eyes were closed because it’s neurological effect not a visual one.

Since my stroke I’ve read a little bit more about them. Before the stroke I read the visual aura are not unusual and lasted 20 minutes. So I was content .

Since my stroke I’ve read that optical strokes are an early warning sign and have these sorts of symptoms so I suspect there are two effects with different causes. one of which is and one of which isn’t so significant - I haven’t seen any published research around this (but I haven’t looked terribly hard) sounds like it’s PhD thesis territory for a student somewhere

Hi I had a headache at the back of my eye then woke up with blurry vision Hemonopia left half of each eye missing, due to 100% blocked right cartroid artery. Doctors said Too risky to unblock. Post stroke, and three years on, I have had very real hallucinations faces morphing into different people etc…and changes in what I see and the colours I see change too, it’s like different filters over the top of my vision, then it settles Again. consultants said it’s the brain playing tricks, unfortunately I am unable to drive but hope one day I can. I tried Nova Vision for the first year a type of light therapy you can buy, think it helped a little with the visual field but not hallucinations colours or shapes.

Now I recall visual migraines in the weeks prior to my stroke they were like jagged flashing lights in the corner of my eye again have had none since would have been nice to know it was a warning sign.

Thanks to all who have made me welcome now off to read some more experiences good luck to you all
