====== Visual Snow syndrome ======

>Patients with so-called ‘visual snow’ describe a persistent disturbance in the entire visual field resembling the ‘static’ or ‘snow’ of a badly-tuned analogue television. The symptoms are continuous and can persist over years. Although many primary care providers, ophthalmologists, neuro-ophthalmologists and neurologists have seen patients with such complaints, the problem remains undefined.

The cause of visual snow is unknown. It's often, but not always, associated with [[content:medicine:diseases:m-q:migraine]], and with a variety of other visual disturbances - and also with the hearing disorder [[content:medicine:diseases:r-z:tinnitus]].

Current research suggests that the syndrome is not an eye problem as such, but appears to be a malfunction in the brain's visual system, specifically in the //right lingual gyrus// and the// left cerebellar anterior lobe.//

There are currently no successful treatments.
