Visual snow and TMS study
Part of Brain & nervous system, Eyes & vision clinical trials.
This study uses a technique called Transcranial Magnetic Stimulation (TMS), which uses magnetic pulses to gently stimulate parts of your brain, to explore how people with visual snow syndrome, color blindness, or normal vision perceive light patterns. This may help understand why visual snow happens and how to treat it.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old.
- You have either visual snow syndrome (confirmed by a doctor), color blindness (confirmed by a color vision test), or no vision or brain disorders (as a healthy volunteer).
- You are not currently taking any psychotropic medications (medicines that affect your mood or thinking).
- You do not have a history of seizures, epilepsy, or any metal implants in your head (TMS safety).
- You are not pregnant.

This study uses visual tests and brain scans to understand how the brain processes vision in people with visual snow syndrome compared to those without. It may help researchers learn more about what causes this condition.
This trial tests whether a type of mindfulness-based therapy can help people with visual snow syndrome (VSS), a condition where you see persistent visual disturbances. It aims to see if this therapy can reduce the distress and improve quality of life for those affected.
This study uses a very strong MRI brain scanner to better understand conditions like migraine, visual snow, or epilepsy that don’t fully respond to treatment. You may be able to join if you meet specific diagnosis and safety requirements for the scanner.
This study uses brain stimulation and brain imaging (MRI) along with vision tests to understand how the brain supports seeing. You might be eligible if you are a healthy adult and can safely complete MRI and stimulation tasks.
This study tests whether transcranial magnetic stimulation (TMS), a non-invasive brain stimulation method, can help restore vision in people with severe high myopia. It is a research treatment that may improve vision by stimulating the brain's visual areas.
This study tests whether a noninvasive brain stimulation treatment (tRNS) plus visual training can improve visual field problems after a stroke. It may help some people regain better visual perception in the area they lost.
