ssociate Professor Joanne Fielding and colleagues are making headway on clarifying the underlying neurological cause of Visual Snow Syndrome. We feature an overview of her recent and forthcoming research here.
A little over three years ago, Monash University Department of Neuroscience researchers Associate Professor Joanne Fielding and Professor Owen White were given a $140,000 to fund research into a neurological condition that was at the time little known and under-researched.
People with Visual Snow Syndrome see the world through a constant overlay of flickering dots passing over their entire field of vision. This persists whether their eyes are open or closed. The incurable condition is not due to eye problems – it’s caused by an unknown brain malfunction.
The donation from the US-based non-profit Visual Snow Initiative (VSI) allowed researchers in the Ocular Motor Research group, including Dr Meaghan Clough and PhD students Emma Solly and Paige Foletta, to conduct a suite of studies using simple eye movement tasks.
Associate Professor Fielding said the team had been busy, notwithstanding COVID-19. Last year, they published three papers on VSS. Two of the studies extended and supported the findings made in a breakthrough 2020 paper published in Neurology that found that people with VSS moved their eyes much faster than healthy controls towards a suddenly-appearing visual stimulus, and when asked to look away were more likely to erroneously move their eyes towards the stimulus.
“The 2020 paper provided the first evidence of objective and quantifiable behavioural changes in patients with Visual Snow Syndrome,” Associate Professor Fielding said. “It provided concrete evidence that VSS is driven by neurological dysfunction,” she said. “For a disorder that was previously considered psychogenic, this evidence is crucial validation for patients that there’s really something wrong.
