    Question Visual Snow

    What do you guys think about the phenomenon of Visual Snow, where a light- and multi-colored haze fills up one's field of vision? Do you think there could be some primal nutrition treatments?

    I've had to live with it all my life, and the one time I mentioned it to an eye doctor he wasn't able to detect anything. Otherwise, my last measurements were 20/20.

    It doesn't interfere with my life greatly, though at times it can fluctuate, and I wonder if it's nutrition related. For instance, when I was a child I was on the poorest version of the SAD, and once while building snowmen I came inside, after being exposed to the light-reflecting snow, to find myself practically blind. My mother asked me to fetch a particular color bow, and I was totally color-blind, them looking all black to me.

    On the other hand, since going Paleo I've been able to pull feats off such as never needing sunglasses on the brightest sunny days and having the snow only sting my eyes a little bit, without any lasting maladies, which suggest it might be health-related.

    What think you?

    Could what you have be like a visual migraine? Like, a rainbow aura that covers your entire field of vision, but with no headache or pain?

    Visual Migraine Animation - YouTube

    I get them occasionally. Mine have always been related to being exposed to quickly flashing lights, like driving past a large row of trees, where the sunlight is dappled through the leaves, and you're quickly driving past shade sun shade sun shade sun. Like that.

    One data point you might find interesting: I get the visual migraines only when I'm in ketosis. I have never had one at any other time. If I increase carbs, no auras.

    Is it just like an alternating, wavy green and red/pink wash of your vision? Just barely noticeable, more so on brighter/light backgrounds?

    Little Vase: Your video doesn't seem to cover what it is that I experience, no.

    Kegas: If I close my eyes it does look red and green, but it's too mild to decipher that when my eyes are open, so I can't tell then.

    What I experience is just a wee bit milder and irregular than what is portrayed in the animated gif shown on this page, which I view as the most accurate portrayal: Visual Snow

    Most of the time visual snow is caused by either migraines, adrenal fatigue, or poor blood flow to the eyes over a period of time. I would try a supplement like this, Super Zeaxanthin with Lutein, Meso-Zeaxanthin Plus Astaxanthin and C3G, 60 softgels, combined with this Eye Pressure Support with Mirtogenol, 30 vegetarian capsules. If those don't help I don't know what will.

    This is almost universal among autism spectrum people. I have it. If I stare at a white wall I see radiating blue and yellow or red blobs dancing, growing, shrinking, etc. My night vision is terrible.

    I have had this. It washed over my eyesight. Weird. It hasn't happened in years.

    Interesting... Now I'm going to have to ask my son and see if he experiences the same thing.

    I am an ophthalmologist, so I guess it is kind of my job to try to answer this one

    First on the defensive side, I presume you see a PCP occasionally, and aren't experiencing any other systemic symptoms. What you are referring to medically called "entopic phenomenon", with some of the big hitters as possible causes....with this said, the fact that you report it all your life makes a difference. Things like MS, cranial compression, or other very serious things are found with this symptom, so it's good to know what it's NOT to start with.

    More realistically, it is likely a neurological synapsal issue that is more physiological that pathological. In many cases of Asperger's, Raynaud's, and some of the X-linked genetic diseases, it is thought that there is insufficient axonal tone in the areas of the visual cortex that work to filter out the "white noise" of your vision.....in other words, the "push back" of some of the visual processing can be interfered with, especially under certain conditions.

    It is benign, and somewhat common, under these circumstances.

    Some red-flags:
    -- Does your vision have a noticeable pattern where this occurs, and does your vision ever worsen....I don't mean the snowy vision, I mean reduced acuity, blur, under certain conditions....I would especially pay attention to when you exercise, so-called "Ulthoff's Phenomenon" that is pathoneumonic for MS.
    -- Is it in both eyes or just one?
    -- Have you had an electrodiagnostics done, such as a VEP, visual gradient, or otherwise? This would be the only true method of determining if there is neurological pathology.

    Hope this helps. Let me know if you have any questions
