I bet you’ve clicked this link and thought – “what on earth is one of those?” Well after much research I discovered that I experienced one last night and felt compulsed to write a quick blog on it!
I had just finished eating my chicken and veg stirfry and consumed a cup of coffee and a small block of dark chocolate. Within minutes of finishing my food and drink there was a strange blur occuring in my eyes. It was as if there was some sleep or some blob right in the centre of each eye. I checked in the mirror and got someone else to check aswell but they couldnt see anything out of the ordinary. The blur and movement became more intense, with the centre clearing and then becoming a bigger ring in my eyes, with it not being as blurry in the centre anymore but sharp lines all flashing every colour of the rainbow! To begin with it reminded me of the ancient computer game Tempest mixed with Geometry Wars!
Closing my eyes I could still vividly see this amazing light show but didn’t know what was actually occurring – was I losing my eye sight? had a drink been spiked? was I having an allergic reaction to something?
Someone else has made an animation to show exactly what the person sees – and this is so accurate! It was like a cross between the Northern Lights and the Hong Kong Symphony of Lights!! Click that start button to play the animation!

It seems that a scintillating scotoma is also known as an aural migraine, which manifests itself first as this amazing visual display followed by an actual ‘head’ migraine. Luckily I didnt get the headache just the visuals.
A list of things that can trigger an attack are :-
certain odours and perfumes
physical or emotional stress
changes in sleep patterns
smoking or exposure to smoke
foods containing tyramine (red wine, aged cheese, smoked fish, chicken livers, figs, and some beans)
monosodium glutamate (MSG)
nitrates (like bacon, hot dogs, and salami)
other foods such as chocolate, nuts, peanut butter, avocado, banana, citrus, onions, dairy products, and fermented or pickled foods
The whole experience lasted the best part of an hour then resided and my vision turned back to normal as it disappeared beyond my periphiral vision! Quite worrying to begin with but in a bizzare way almost quite enjoyable from a visual point of view! Let’s hope it’s a long time before I have another attack!
