Symptoms of Visual Snow


Visual snow is a rare condition characterized by the presence of tiny, flickering dots or static-like patterns in a person's visual field. These visual disturbances can significantly impact a person's quality of life and may be accompanied by other symptoms. While the exact cause of visual snow is still unknown, researchers believe it may be related to hyperexcitability of the visual cortex or abnormalities in the brain's processing of visual information.



1. Visual Disturbances: The hallmark symptom of visual snow is the persistent presence of tiny, flickering dots or static-like patterns across a person's entire visual field. These dots may resemble television static or snowflakes and can be more noticeable in low-light conditions or against plain backgrounds. The visual disturbances are typically present in both eyes and may persist throughout the day.



2. Impaired Vision: Visual snow can cause a range of visual impairments, including reduced contrast sensitivity, difficulty focusing, and blurry vision. Some individuals may also experience afterimages or trails when looking at moving objects or bright lights. These visual impairments can make it challenging to read, drive, or perform other daily activities that require clear vision.



3. Photophobia: Many individuals with visual snow experience heightened sensitivity to light, a condition known as photophobia. Bright lights, such as sunlight or fluorescent bulbs, can exacerbate visual snow symptoms and cause discomfort or pain. Photophobia can lead to a reluctance to go outside or avoid environments with bright lighting.



4. Tinnitus: Tinnitus, or ringing in the ears, is commonly reported by individuals with visual snow. The ringing sound can vary in intensity and may be constant or intermittent. The relationship between visual snow and tinnitus is not fully understood, but both conditions may share similar underlying mechanisms.



5. Other Visual Symptoms: In addition to visual disturbances, visual snow can be accompanied by other visual symptoms. These may include floaters (small specks or threads that float across the visual field), nyctalopia (difficulty seeing in low-light conditions), and entoptic phenomena (perceiving one's own blood vessels or white blood cells moving in the visual field).



6. Cognitive and Emotional Effects: Visual snow can have cognitive and emotional effects on individuals. Some people may experience difficulties with concentration, memory, or processing visual information. The constant visual disturbances can also lead to anxiety, depression, or feelings of frustration and isolation.



7. Variability: The severity and frequency of visual snow symptoms can vary among individuals. Some people may have mild symptoms that are tolerable, while others may experience more severe and debilitating symptoms. The symptoms may also fluctuate over time, with periods of improvement or worsening.



If you are experiencing persistent visual disturbances or any of the symptoms mentioned above, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate management strategies. While there is no specific cure for visual snow, various treatment options, including medications, lifestyle modifications, and visual rehabilitation techniques, may help alleviate the symptoms and improve quality of life.

It varies from person to person, but most commonly it would be described as many static, or snow-like dots in the field of vision.

Light sensitivity - when it's very bright outside and I walk out after being in a darker room, I get blinded by the light to the point that it hurts my head

Static in your vision. When looking at white backgrounds or screens, the snow or static is much more prevalent. My visual snow gave me really Palinopsia or afterimages and trailers. On old TVs, if they were left on one screen for too long, it would burn into the screen and be visible forever. This is what afterimages is like, except it is a temporary afterimage. It's not a direct copy, but generally an outline of the object you were looking at. For example, if you were looking at a screen, the afterimage would look like a black box with a white outline. If it is a light color, it has a dark afterimage, and vice versa. I also developed a number of eye floaters, or these black spec or streaks in my vision that float around the vicinity of my vision. Other things that I had developed was photophobia (light sensitivity) and blue field entopic phenomenon (blue trails bouncing around my vision). The blue field entopic phenomenon is very evident when looking at the sky on a sunny day. Nonetheless, not everyone experiences all of these symptoms, and some might have all of it. Visual snow is a complicated disease that is still going through some much needed studies.

The most prominent symptom of Visual Snow for me is a constant static that always is overlaid in my visual field. The best way to describe the static is by comparing it to static on the tv that is overlaid onto my vision. This static is seen even when I close my eyes.

It is really hard to see at night due to white dots all over the place.

There are a couple kinds of visual snow but I can only speak to mine. Since I was young, I've seen dots ..infinitesimally small dots. Some collect light and some are dark. The light collectors work when there's light but don't always release that light at night. Sometimes at night with my eyes closed, these light collectors shine softly still. Then a wash of dark covers over the light repeatedly until the light shines no more. I used to watch this process and wonder if I wasn't seeing the visual purple of the rods working. Some people report seeing these dots move around, but to me, they move with my eye, not independently by themselves. I've always had better than 20/20 (corrected) vision. They don't interfere with what I see. Normally. As I age, I've become more aware of them and in that, they may be beginning to "interfere ". I also have tinnitus. Had it forever, too. The doctor said I had to learn to ignore it which I mostly have. I generally ignore the visual snow, until I don't!

Symptoms vary on an individual basis but tend to always include the presence of small, innumerable, dots in your vision. This occurs when eyes are open or closed. These can vary in size, shape and colour. Most sufferers seem to see black and white dots. Other visual symptoms include ‘after images’, light sensitivity, flickering, light auras and floaters. Non visual symptoms and severity also vary but include tinnitus, confusion and insomnia.

-Tiny, snow-like dots across the visual field -Sensitivity to light (photophobia) -Continuing to see an image after it is no longer in the field of vision (palinopsia) -Difficulty seeing at night (nyctalopia) -Seeing images from within the eye itself (entoptic phenomena) -Tinnitus

https://www.verywellhealth.com/visual-snow-syndrome-1719607 For a diagnosis of Visual Snow Syndrome (VSS) you must have experienced the following:- 1. At least 3 of the below symptoms for over 3 months. Floaters, the small shapes you may see in your visual field Photopsia, the starbursts or flashes of light that may suggest a health issue Nyctalopia, or impaired night vision Kaleidoscope vision, the color swirls often seen with migraines Palinopsia, or seeing something that isn't there anymore Photophobia, a heightened or unusual light sensitivity Non-Visual Symptoms With visual snow syndrome, there may be other symptoms besides what you see. Symptoms that aren't visual include: Migraines, a disabling headache often linked to visual migraine aura symptoms Tinnitus, or ringing in the ears Vertigo, a sense of spinning or dizziness, or balance loss Fatigue, an unusual exhaustion often related to another health issue Tremors, an uncontrollable motion in your body, often the hands Anxiety, a mild to severe response to stress Depression, a mood disorder associated with feelings of sadness and fatigue 2. No history of hallucinogenic drug use (LSD / Magic Mushrooms etc). 3. No physiological degeneration of your eye. An Optician or Ophthalmologist should be able to check this for you.
