Shedding Light on Visual Snow: Insights from the ACBO Conference

Earlier this year, our two optometrists SooJin Nam and Frances Grasso attended the Australian College of Behavioural Optometry (ACBO) Visual Snow Conference led by internationally acclaimed Dr. Terry Tsang and Dr. Charles Shidlofsky. 

The conference highlighted the Tsang–Shidlofsky protocol to treat visual issues of the Visual Snow syndrome, which is currently the only known effective treatment and which has been found to significantly reduce symptoms in 80% of those treated.

What is Visual Snow Syndrome?

Visual snow is a rare neurological condition that impacts an individual’s vision, hearing, cognition, sensory processing, and quality of life. It is characterised by the perception of what appears to be “visual noise” or “static” in a person’s field of vision. People with visual snow report seeing what looks like a constant, dynamic pattern of tiny, pixel-like dots or graininess superimposed on their visual field – think the static seen on a malfunctioning television screen.

This phenomenon can make it challenging for affected individuals to see clearly and comfortably. The incurable condition is not due to eye problems – it’s caused by an unknown brain malfunction. It is important to note that this persists whether the eyes are open or closed.

The exact cause of visual snow is not fully understood, but it is believed to be a neurological disorder involving abnormal processing of visual information in the brain. Researchers are actively studying the condition to better understand its underlying mechanisms and to develop effective treatments.
