The Optometric Vision Development and Rehabilitation Association’s (OVDRA) Annual Meeting in Louisville, Kentucky, featured an educational lecture focused on the management of Visual Snow Syndrome (VSS).
The course, titled “Current Neuro-Optometric Management of Visual Snow Syndrome,” was presented by Dr. Leanna Dudley and Dr. Esther Han, both VSI collaborators and featured on the VSI’s Global Physicians Directory. More than 325 neuro-optometrists and vision rehabilitation professionals attended the 2-hour session, making it one of the most attended lectures at the meeting.
The presentation focused on the clinical evaluation, differential diagnosis, and neuro-optometric treatment approaches for patients living with Visual Snow Syndrome.
Understanding Visual Snow Syndrome
VSS is a neurological condition that can affect vision, hearing, sensory processing, cognition, and quality of life. The condition is named after its main symptom, “visual snow,” which is often described as seeing continuous flickering dots, static, or television-like snow across the entire visual field 24/7, with eyes open or closed. Many individuals compare it to looking through a snowstorm, static, or a shaken snow globe.
In addition to visual snow, many individuals with VSS experience a wide range of visual and non-visual symptoms, including:
- Palinopsia (afterimages and trailing)
- Floaters and other entoptic phenomena
- Light sensitivity (photophobia)
- Night blindness (nyctalopia)
- Tinnitus
- Migraines
- Dizziness and vertigo
- Brain fog and difficulty concentrating
- Sensory overload and cognitive fatigue
Symptoms and severity can vary significantly from person to person, and many patients experience multiple symptoms simultaneously.
Because VSS is a neurological condition involving visual processing and sensory integration dysfunction, many patients report symptoms that extend beyond what is typically identified through standard eye examinations. This is one reason why neuro-optometrists can play an important role in helping evaluate and manage the condition.
Clinical Evaluation and Neuro-Optometric Treatment Approaches
The lecture also explored common co-morbidities frequently reported in individuals living with Visual Snow Syndrome, including:
- Postural Orthostatic Tachycardia Syndrome (POTS)
- Ehlers-Danlos Syndrome (EDS)
- Migraines
- Post-concussive symptoms
- Vestibular dysfunction
Speakers discussed the importance of individualized and multidisciplinary treatment approaches when managing patients with complex neurological and sensory symptoms.
The Expanding Role of Neuro-Optometrists in VSS Care
The lecture emphasized the increasingly important role neuro-optometrists serve in the management of Visual Snow Syndrome. Because VSS frequently involves complex visual processing and sensory integration dysfunction, neuro-optometrists are uniquely positioned to provide targeted evaluation and rehabilitation strategies that are often unavailable elsewhere within the healthcare system.
“Our goal was not only to share current evidence, but also to equip more providers with practical tools to better support this underserved patient population,” Dr. Dudley explained.
As awareness and research surrounding Visual Snow Syndrome continue to grow, educational programs such as this lecture help expand clinical understanding and encourage more informed, patient-centered care for individuals living with VSS worldwide.
