Visual Snow Syndrome

VSS Masterclass for Physicians

Next Stop:

Toronto, Canada

The masterclass is affiliated with the Council on Optometric Practitioner Education (COPE), a nationally recognized accreditation program for optometric continuing education (CE) courses.

Physicians worldwide are invited to a 2-day (12-hour) masterclass on recognizing and treating Visual Snow Syndrome.

The Visual Snow Initiative brought together Dr. Charles Shidlofsky and Dr. Terry Tsang to collaborate on clinical research involving assessing and managing Visual Snow Syndrome. They presented their initial research at the 2022 Visual Snow Initiative Virtual Summit and published their official Visual Snow Syndrome treatment protocol, Neuro-Optometric Visual Rehabilitation Therapy (NORT), in Frontiers.

Our mission is to equip physicians with the knowledge and skills to make a positive impact on patient care, and to advance the understanding, management, and treatment of Visual Snow Syndrome globally.
