Second Ocular Migraine Incident

About a month ago I wrote that I had something called kaleidoscopic vision, also known as an ocular migraine. It literally came and went without any repercussions or actual pain. It was just a weird experience, and it had me worried because I’ve never experienced it, nor did I know what it was until we researched this effect. Today at around 9:10pm EST it happened again. Just like before, it lasted for just over 20 minutes and disappeared as if someone had flicked a switch.

This episode was somewhat milder than my previous one. I had about a quarter of zig-zag vision in the top right corner of my vision, unlike last time where it seemed to be in a 360 degree circle. This time it only covered 90 degrees. After about 10 minutes, the zig-zag patterns had shifted further outside, into something of a stretched line. There was less colour involved than last time.

I suppose knowing what this is means there’s less immediate panic, however I do worry that this thing has come back in such a short interval. I’m due an eye exam anyway, and my primary glasses have lost a node pad on the right hand side, so I’ll make an appointment with Dr. Shapiro at Four Eyes soon and tell him what happened. Doctors like notes, that’s why I’m taking them.

What may have changed since last time?

Symptoms aside, it might be an idea to note any lifestyle changes that have happened recently, and/or since last time this occurred. I can’t think of dietary changes, and I’m still drinking mostly decaf (with an intake of 30% caffeinated at the most, if at all). I sleep OK, except for perhaps list due to heavy rain. I decided to get up at 4am and do some editing, then go back to bed at around 7am.

I have been streaming almost daily though, with two shows at weekends. It’s fun and fulfilling, very productive and I surprise myself with the 3D projects that are happening as a result. The setup in Studio C isn’t great (aka the linen cupboard), but it’s working. I do utilise my old glasses there though, which I seem to remember are over-correcting my vision a bit. i don’t have any headaches, but due to increased streaming activity, I do wear them more than usual. Perhaps it’s related, perhaps it isn’t – I wasn’t streaming this much when the first incident occurred.

More news as it breaks.

Kaleidoscopic Vision Experience

I’ve just had an interesting experience while watching TV (The Mentalist, season 1, episode 2). It’s something that appears to have been Kaleidiscopic Vision. Here’s how I’ve described it to Julia, trying to work out how this thing came about: my peripheral vision was fine, so was the centre of my vision, but there were two circles around the centre that were flickering like small sticks, in all colours of the rainbow.

I was trying to work out if this phenomenon appeared in one eye or on both, which was a little tricky as the image I was seeing was an amalgamation of both eyes. Closing either one of them revealed that it did not make a difference, so bizarrely it was happening on both eyes. This in turn seemed to suggest that it was not eye related, but rather brain related. In computer terms, the visual processing happens after signals are being received from both eyes.

Closing my eyes did not seam to have an impact as the little rainbow sticks kept dancing in a circle in the dark. There were no accompanying symptoms like a headache or migraine, nor did I feel dizzy. I had a crazing for salty snacks if that’s a symptom, which I duly squashed with a handful of cheesy Chex Mix.

A quick web search revealed the possible name for my experience: Kaleidoscopic Vision. While it could be related to something more serious, the articles suggest it’ll disappear within 30 minutes. And right they were: it occurred about halfway through that Mentalist episode, and disappeared about 10 minutes into the next, rather rapidly I might add. as if someone had flicked a switch.

Although causes may vary, one article suggested this may be related to caffeine withdrawal (which I’ve had recently), as well as hyper stimulation. That too is true: having had my head buried rather deep in two complex 3D programmes yesterday (CLO and Marvelous Designer), while dealing with a bit of web server administration. Today I was involved involved in the production of a complex YouTube video about something called the Filament Render Engine in DAZ Studio. Am I using my brain too much perhaps?

I took two aspirin just in case this thing would turn into a headache, a trick I’ve learnt from my dentist Dr. Oliver, after he removed my wisdom teeth: Rather than wait for the pain, take pain killers before the onset and things will be much more tolerable. Just in case.

I’ll see how this thing pans out. The phenomenon is gone for now, but I thought I’d make a quick note here to have a sequence of events and a little context. I’ll keep you posted if it happens again, or in fact if anything else health related is happening in my life.

Switching back to Decaf

I’ve had an interesting experience with myself last week: I switched to decaf, after having caffeine creep into my coffee consumption more and more recently. After my treatment, I abstained from caffeine for a while, and eventually added a spoon of caffeinated coffee into my own special mixture I’d like to call “third-caf”, made up of two spoons of Folgers decaf and one spoon of Bustelo. I really liked the taste.

my coffee stash – I don’t like running low, it’s a real luxury for me

Over time, a second spoon of “real” coffee crept in, and over the last three months or so, I found myself on fully caffeinated Bustelo again. It’s the only vice I have left, and I didn’t see it doing any harm to my system, nor did I receive any adverse messages from my body. Until last week, when I had a full pot of decaf.

Julia doesn’t drink coffee, because of the caffeine, but she does enjoy the smell of a fresh cup of Joe or a newly opened pack of coffee. With decaf, she even joins me for a cup sometimes (otherwise she’s more of a decaf tea person). I liked the pure decaf taste, and also didn’t think it would do anything adverse.

Then however one of those numb non-localised headaches came to visit me. Those you can kind of live with, but life would certainly better without. Many familiar with this phenomenon will quickly recognise it as caffeine withdrawal syndrome. Apparently it’s caused by an increased amount of blood going to the brain, or rather the “normal” amount of blood going to the brain.

Caffeine has the bad side effect that it actually restricts blood flow to the brain, causing a kind of “controlled stress”, with the effect of us being more alert. That’s why we like it so much. As we indulge on caffeine, our body gets used to it, as we get used to its effects. When we stop taking it, our body needs to get used to that lack of stress induction first, which can cause a whole host of effects in some users:

  • headaches
  • anxiety
  • depression
  • difficulty to concentrate
  • flu-like symptoms
  • fatigue

There is of course a scale to this phenomenon, and mine was a very mild case, yet strong enough to make be aware. A few days of complete coffee abstinence followed, and now I’m back on the full decaf (which depending on where you get it from, and how strong you brew it, still contains a small amount of caffeine; I remember a Starbucks’ decaf [on the slim chance they actually have one brewing] is strong enough to make me feel the caffeine).

I’m telling you all this because today I tried to smuggle a spoon full of caffeinated Bustelo into my daily mix, thinking what a nice treat the flavour variation might be. And while I enjoyed that taste indeed, the caffeine effect wasn’t working for me. It’s fairly new behaviour for me to react immediately and honour that feeling in my body by pouring out that Thermos and making myself a fresh pot of 100% decaf.

Back in the day I would have just “started doing that tomorrow” and continue drinking the mix I had readily available, suppressing my feelings with thoughts like “don’t be such a wuss and get on with it, you’ll be fine”. Every addict knows that voice. The real power is in breaking it there and then, and NOT continuing with current behaviour and acting immediately. That’s what puts you in charge, and that’s what makes a change and a difference.

So yes. I’m back on the decaf, and I’m proud of being aware of what just happened there 😎
