Something regards Visual Snow Symptoms

The study's findings suggest that visual snow symptoms worsen with color modulation that increases S-cone excitation. The authors theorize that this is because S-cone signals travel on primordial brain pathways that regulate cortical rhythms (koniocellular pathways), which may contribute to the development of visual snow disorder.

We can help our patients reduce their visual snow symptoms or even improve their quality of life. Please make an appointment and consult with our vision specialist.
