Visual Snow Syndrome (VSS) is a neurological condition that affects an estimated 2–3% of the global population. Despite its prevalence, it remains widely misunderstood. In a recent segment on CT das radio, journalist Mascha Buck explored the impact of this condition through interviews with Professor Dr. Dagny Holle-Lee and Sierra Domb, founder of the Visual Snow Initiative.

The radio feature opens with a striking analogy: imagine viewing the world as if through the static of an old analog television screen—continuously. For people living with Visual Snow Syndrome, this is often their everyday experience.
Professor Dr. Dagny Holle-Lee, Head of the West German Headache and Vertigo Center in the Department of Neurology at Essen University Hospital, is one of Germany’s leading specialists on VSS. She regularly sees patients with a wide range of symptoms and is listed in the Visual Snow Initiative’s Global Physicians & Specialists Directory, which connects individuals to trusted professionals worldwide.
English Transcript of the CT das radio Segment
Most of you are probably still familiar with the pixelated screens of old analog televisions. Imagine seeing the whole world pixelated like that—around the clock.
Prof. Dr. Dagny Holle-Lee:
“So what you see, for example, is that there is suddenly a kind of tail behind objects. You often see double contours around objects, you suddenly see flashing things in the sky, for example. Night blindness is very common. Migraine is also a frequent association.”
The symptoms of Visual Snow Syndrome are varied and can range in severity. Some individuals may have experienced visual disturbances from an early age, not realizing their perception differs from others. For others, symptoms may become debilitating, interfering with daily life.
In addition to visual disruptions, patients often report tinnitus, depersonalization, or a persistent sense of disconnection from their surroundings. Though research into VSS is still developing, important progress has been made in recent years toward understanding its neurological basis.
Prof. Dr. Dagny Holle-Lee:
“So we now know that it is probably caused by certain brain centers involved in image processing working too well or differently. Otherwise, I think the most important thing that has happened in recent years is that the syndrome has become known at all. Previously, patients were always sent to a psychosomatist or psychiatrist because people believed they were imagining it—but that’s no longer the case, thanks to increased awareness.”
While awareness is growing, treatment remains complex. There is currently no one-size-fits-all solution. However, some management strategies can help alleviate symptoms.
Sierra Domb, founder of the Visual Snow Initiative, was diagnosed with VSS in her early twenties. Through VSI, she has dedicated herself to supporting patients and promoting research. In the interview, she shares practical tools for coping with symptoms.
Sierra Domb
“Dulling your senses when things are too loud or too bright with glasses or earplugs and sort of creating a calm environment for your nervous system is one of the best things you can do for VSS. And VSS gets worse with stress for so many people—physical stress or mental stress: there’s a direct correlation. It can cause flare-ups. It won’t necessarily make it worse permanently for everyone, but why give yourself a harder time when you can avoid it, right?”
