What is your approach to the treatment of visual snow syndrome?

Visual snow is not a syndrome. It's a symptom that consists of static vision. I opine that it's origin is retinal (not brain) and that it relates to ongoing activity. In the past I have referred to it as retinal repolarization disorder. It should not be confused with migraine aura status, which is a totally different problem. Here we're dealing with a migraine aura, usually visual and typically in the form of a scintillating scotoma, that does not die out and lasts well beyond its usual duration...
