Regular Visitor Posts: 413 02/10/08 2:22 PM	Remove this ad I'm trying to quantify the effects of various stimuli on my VS through the magic of self-experimentation. I had enough of anicdotes, and tried using the scientific method, or at least the controlled experiment and observation part of it... Worse is defined as significantly denser and brighter (and darker) spots, the appearance of aura-like geometric shapes and a feeling of disconnectedness/foggy-brained. I have found that I can make the VS much worse on demand 100% of the time by doing the following: - Going from a semi-dark room to a very bright room. - Going from a bright room or outside to a dark room. - Simply looking at a grey, light blue or beige low contrast wall. - Looking at an object with contrasting luminances - brighter and darker areas. - Looking out a very bright window, then at a beige or taupe wall - this has made me feel like I'm vibrating around 20-30% of the time. - Also when I wake in the middle of the night and in the morning my VS is always significantly worse - I've only had one episode where I felt like I was vibrating when waking. - The VS gets better shortly after waking up, then gets worse as the day progresses. Computer work or watching tv, or anything listed above seems to accellerate degeneration. - Concentrating - for example, writing poetry, seems to increase my VS as well. I've tried this on five different days, performing different tasks that didn't require visual acuity and found it to be true each time. Does everyone/anyone else have any of these things? Jim

I often find when I'm engrossed in deep concentration I don't notice anything with visuals (they're probably still there, but my attention is elsewhere). Need to cheer yourself up?

I think my dreams can alter my VS because sometimes i wake up and my VS is CRAZY for 5 seconds or so then it returns to normal levels. I've mentioned this in another thread but i can alter my VS by playing Guitar Hero intensely for half an hour or so. As it's a fast vertical scrolling game it will make my VS move vertically, like it's raining (like a slow drizzle). It will remain that way for 5 minutes or so (never really timed it).

He said mine was pretty obvious persistent migraine aura and told me the grainy vision was called visual snow. He showed me a simulator and everything. It was a bit of a revelation, since I had no clue what was going on and had already been through 3 ophthalmologists at the med school. I have a lot of pretty classic migraine aura stuff that happens all the time, but for some reason I never connected them in my head since a migraine aura that lasted more than an hour seemed logically impossible to me.

When you wake in the middle of the night with the VS being significantly worse, do you recall having dreamt before awakening? The one episode where you felt like vibrating when waking, was that waking in the night or in the morning? Do you recall a preceding dream?

Regular Visitor Posts: 413 02/11/08 8:19 PM	No, I don't recall having a dream before waking and having bad VS nor when vibrating. The few times I do remember waking from a dream my VS was bad, but not insane. I haven't been remembering many dreams lately, which is odd because I normally have very vivid and odd dreams, I wonder if I have a developed a sleep disorder? I awoke vibrating in the middle of the night. Maybe 2am? Regarding sparkles, I should be able to make a drawing tomorrow morning when my eyes are a bit better - I think I've figured out what they are. We've finally had some blue sky and during some experimentation I was able to increase the frequency and intensity of the sparkles. With a little will power I was able to create a totally new experience. 1. I look into the blue sky without blinking. The sparkles appear within a few seconds. 2. Continue to stare, within 10 to 15 seconds, the sparkles become hundreds apon hundreds (maybe thousands) of small worm like crescent shapes which are very aura like in appearance, almost like a sky full of miniature auras. The C shaped worms face in all directions, shimmer in and out of existence very quickly and seem to move in random directions very slowly. After maybe 5 or 10 seconds of this I am unable to continue looking do to a near irresistable urge to look away. Afterwards I feel light headed and a bit disoriented. During the "worms" I feel like I am about to get a migraine. I would wager that I could trigger a migraine like this on demand with enough will power - not something I'm willing to test unless there's some wires hooked to my head and a greater good to be served. I did this three times today and each time was identical. I feel I can reproduce this again. Jim Last Edited By: jruddy 02/11/08 10:02 PM. Edited 1 time.

Regular Visitor Posts: 413 02/11/08 10:01 PM	Just to clarify - if I take a quick nap, the VS is much worse when I wake up. If I simply lay down and close my eyes for 10 minutes, the VS is worse. If I allow myself to "stare off into space" - not focus on anything - the VS gets worse. During the morning hours, when my VS isn't too bad, focussing on something like a computer screen or text on paper can actually push the VS out of the middle of my vision - it's still snowy all around it, but what I am concentrating on is clear. It's like if I can force myself to focus on it hard enough on something I can force it to be clear, but as fatigue kicks in, it becomes impossible and the VS gets very bad and I start getting double vision, after images, worse snow, etc...

Posts: 1496 02/12/08 11:15 AM Administrator	Remove this ad oooooo.... sky worms! If I see something like that, sparkly and whatnot, it is not all over the place. I'm going to have to try that the next time we have blue sky! I definitely get the same VS worsening that you do. I get the vibrating too. Last weekend I had a dream I was spinning around in circles uncontrollably (hovering over my bed, no less) and then I woke up dizzy and stayed dizzy for two days. Actually, I'm still dizzy.

They start out as very quick moving flashes - eventually it becomes obvious that the movement is in the worm shape. I often get these in the corner of my eye - they are bright, shimmery - very aura like and very distracting. I also get them in front of my vision in brighter light though I don't see the worms against grey skies. (I just tried, there was something there, but I couldn't make it out, I wonder if it is because the worms are kind of grey/silver themselves?)

Regular Visitor Posts: 413 02/22/08 11:06 AM	Today I was trying to get some reading done for my night school (one day a week at the local university, it's paid for so I might as well continue) I read until my vision got too bad, then out of habit I went and looked outside - this is my old trick for relieving eye strain - which this isn't... habits are hard to break though... Anyways, it's a grey overcast day, but what do you think appeared in the sky... Skyworms!!!! So I can get them in grey sky as well as blue. I thought as much - but hadn't had any luck until now. Anyways, my vision's all doubled up from reading and snow is awful so cheers for now... Jim

Registered User Posts: 5010 02/22/08 1:40 PM	The observation that the "skyworms" occur against a grey sky is an argument against it being just the blue field entoptic phenomenon. Could you make an illustration showing the skyworms against the grey sky?

The interior of the worms are less distinct against a grey sky, but the edges became very obvious. I noticed when reading that the letters all had developed bad glows before I developed double vision, as well the glow around my couch etc... got worse too. Perhaps the glows are related? Just a theory.

" Previously you only described the increased halos around lights, but not glows around non-light emitting objects (like letters or couch). Do you have this visual phenomenon (glows, extra-contopurs around subjects) as a daily symptom or just as a transitory symptom, sometimes?

Regular Visitor Posts: 413 02/23/08 8:43 AM	Remove this ad I'm sorry, I thought I mentioned the glow around the couch before. It is a constant, very slim glow around dark objects against bright backgrounds. I've not seen it get as bad as the 2nd blue jay picture but it does get worse, especially if I;ve been reading. (or rather trying to read) I seem to be able to read for around an hour in the morning, maybe 15 minutes in the evening before the glow becomes top bad. If I push on, I develop the double vision. I've done this quite a few times lately and am sure this is the sequence. Let me guess... can I post a pic?
