What’s Visual Snow Syndrome (VSS), and why do so many autistic people have it?

I learned about this the other day, when I posted about palinopsia (visual trailing/afterimages) being common in autistic people, and a couple of our followers told me about their VSS. I did some more research, and discovered that I also have it.

Visual Snow Syndrome is a neurological condition that interferes with visual processing. It’s caused by hyperactivity and hyper-excitability of nerves in certain areas of the brain that process visual information.

The core feature of VSS is constantly seeing tiny, fuzzy “feedback” in the environment. It’s kind of like seeing the world through a staticky TV screen. Some people’s visual static is larger than others. Mine is relatively fine-grained, but it gets bigger and more obvious in low lighting.

Some of the other symptoms of VSS include:

  • Palinopsia (visual trailing/afterimages)
  • Photophobia (sensitivity to light)
  • Increased and enhanced ectopic phenomenon, such as floaters, phosphenes, and Scheerer’s phenomenon
  • Seeing glare, starbursts, and halos around lights
  • Difficulty seeing at night/in the dark
  • Seeing random flashes of light and/or color, without cause from the environment

It’s common for people with VSS to experience comorbid migraines, but VSS is not the same thing as migraine aura.

So, why do autistic people often have VSS?

It comes down to the fact that VSS is caused by the hyper-excitability of neurons in areas of the brain that process visual information. A core feature of autism is hyper-excitable neurons, especially in areas of the brain that have to do with sensory processing. So it makes sense that autism would often inadvertently cause VSS.

Here are some illustrations of visual phenomenon that VSS causes, in case you want a better understanding of what the world looks like for me and many other autistic people.

I hope y’all have learned something :)

I’ve found it very intriguing to realize that the way I see the world is more unique than I once knew!

Oh, no, my friend, @aceyuurikatsuki . It’s not just that. It is so much more. Settle down and let your friendly neighborhood x-ray tech explain you a thing.

Throckmorton’s Sign, otherwise known as Throckmorton’s Principle, does in fact have to do with dicks. Because it is fairly normal for a dick to show up on a hip or pelvis x-ray. But the thing about Throckmorton’s Sign is, it’s not just that the dick is visible. It is a legitimate diagnostic tool.

Let me explain: let’s say a person equipped with a penis is in a car accident and has right leg and right side hip/pelvic pain. Their doctor will order x-rays. Unfortunately, sometimes fractures are so small that they can be missed, or, because the patient is in such bad shape and the images obtained aren’t the best quality, the radiologist can’t be sure for one reason or another if what they’re seeing is actually a fracture.

So what do they do? They look for the dick.

You heard me correctly. The dick.

Throckmorton’s Sign is when “the penis points to the area of pain.” So if the above-mentioned AMAB patient’s xray aren’t displaying a clear, obvious fracture, but their dick is pointing to the right side, 9 times out of 10, the injury or fracture is on the right hip or leg area, so then the radiologist will focus on that side while reading.

Now I know what my non-radiology followers are thinking. “Ace, this sounds like bullshit. This can’t be true. You’re lying through your teeth.” But I swear to you, it is 100% accurate. I have seen a positive Throckmorton’s Sign multiple times with my own eyes over the course of the past 7 years. Ask any x-ray tech, and they will probably agree with me.

Your dick is good for at least one thing, and that thing is helping a radiologist diagnose your upper femur, hip, or pelvic fracture.

This had been a PSA.

holy fucking shit
