About Dr. Roderic Gillilan

Discoverer of the SEE Sick Syndrome and developer of Dynamic Adaptive Vision Therapy.

The SEE Sick Syndrome describes a collection of symptoms that many people experience but often cannot name. Nausea, headaches, dizziness, and fatigue during everyday activities like riding in a car, shopping, reading, or watching movies point to a deeper visual processing issue. Those with the syndrome also tend to be extra sensitive to light and movement in their surroundings. This condition was identified and named by Dr. Roderic Gillilan, who recognized that these seemingly unrelated symptoms share a common root in how the eyes and brain work together. Understanding that these struggles have a name and a cause is the first step toward finding meaningful relief.

Dr. Roderic Gillilan, the discoverer of the SEE Sick Syndrome, developed a specialized approach known as Dynamic Adaptive Vision Therapy. This therapy targets the underlying visual processing problems that trigger the uncomfortable symptoms associated with the condition. Rather than simply treating each symptom individually, the therapy addresses the root cause by retraining the visual system to function more effectively. Dr. Gillilan's background in optometry and his years of research and clinical work led him to create techniques that help patients adapt to visual demands. His work has been shared through lectures, articles, and published materials aimed at both patients and eye care professionals.

The symptoms of the SEE Sick Syndrome can significantly impact daily life and limit activities that others take for granted. Simple tasks like a trip to the grocery store, a short car ride, or reading a book may trigger waves of discomfort. Many sufferers have spent years visiting various doctors without finding answers, often being told their symptoms are not real or are simply anxiety. The syndrome represents a neuro-ocular-vestibular dysfunction, meaning it involves the connection between the eyes, the inner ear, and the brain. Recognizing this connection allows for targeted treatment that can restore comfort and confidence in everyday movement and visual tasks.

Dynamic Adaptive Vision Therapy offers hope to those who have struggled with unexplained motion sickness and visual discomfort. The therapy involves a series of exercises and techniques designed to improve how the visual system processes motion and spatial information. Patients learn to adapt to visual environments that once triggered their symptoms, gradually building tolerance and reducing sensitivity. The approach is non-invasive and drug-free, focusing on retraining the brain rather than masking symptoms. For many, this therapy has been life-changing, allowing them to return to activities they had avoided for years. Continued research and patient success stories continue to validate Dr. Gillilan's groundbreaking work.

Biography

Dr. Roderic W. Gillilan, OD, discovered the SEE Sick Syndrome (SSS) and dedicated decades of clinical practice to identifying and treating the condition. His work established the foundation for Dynamic Adaptive Vision Therapy (DAVT) as a drug-free approach to managing motion-related visual symptoms.

Education

Dr. Gillilan received his Doctor of Optometry degree from Pacific University College of Optometry in 1956.

Practice & Military Service

He practiced optometry in the US Army from 1956 to 1958, then went on to run a private practice in Eugene, Oregon, from 1958 through 2000.

Discoverer of SSS: Dr. Gillilan successfully treated the first SSS patient in 1965 and personally trained several hundred patients through the year 2000.
