Optometry & Visual Performance 151 Volume 14 | Issue 2 | June 2026 In this case, syntonic intervention may have contributed to improved visual comfort and reduced sensory overload, thereby allowing the patient to better tolerate and engage in multisensory training tasks. Additionally, the inclusion of at-home lightbox therapy provided important continuity of care and likely reinforced treatment effects through consistent repetition and ongoing neural stimulation.19 The home lightbox was specifically designed to deliver magenta light only, aligning with the initial phase of the syntonic phototherapy sequence used during inoffice treatment. The patient was given the lightbox and was instructed to use the device twice daily for 20 minutes per session over 18 consecutive days, creating a structured and intensive home-based intervention. This frequency and consistency of exposure supported sustained neuromodulation of the visual and autonomic systems, helping to stabilize and to extend the therapeutic gains achieved during clinic sessions. By maintaining regular stimulation outside of the clinical environment, this home-based component enhanced neuroplastic adaptation, reduced regression between visits, and contributed to the overall durability of treatment outcomes.20 Such an approach underscores the value of integrating targeted, protocol-driven home therapy to complement in-office care and promotes longerterm functional improvement. When considered together, OMST and syntonic phototherapy appear to offer a complementary therapeutic framework. OMST actively trains sensorimotor integration through dynamic, taskoriented activities, while syntonics may optimize the underlying physiological state of the visual system by regulating autonomic tone and enhancing baseline processing efficiency. Clinically, this combination may allow for more rapid progression through therapy and improved patient tolerance, particularly in individuals with heightened sensory sensitivity following neurological insult. Importantly, the absence of other concurrent therapies in this case strengthens the likelihood that the observed improvements were attributable to OMST and its associated components. Both objective findings and subjective symptom reduction were substantial, supporting a meaningful clinical response rather than a coincidental or placebo effect. While this report represents a single case, the magnitude of improvement, particularly in oculomotor performance and functional visual outcomes, supports further investigation into OMST as a viable treatment modality for patients with VSS and PCS. Future research should focus on larger cohort studies, standardized outcome measures, and controlled trials to define treatment protocols better, to isolate contributing components such as syntonic phototherapy, and to validate the reproducibility of these results. Conclusion OMST demonstrated significant clinical benefits in a patient with post-concussive visual snow syndrome, with meaningful improvements observed in both objective oculomotor performance and subjective symptom reduction. Enhanced saccadic accuracy, fixation stability, and pursuit tracking were strongly associated with reductions in visual disturbance, perceptual noise, and overall postconcussive symptom burden. As eye movement efficiency improved, the patient experienced greater visual clarity, improved tolerance for sustained visual tasks, and enhanced daily functioning, emphasizing the important relationship between oculomotor control and functional recovery following mTBI. The findings also highlight the value of OMST’s multisensory rehabilitation approach, which integrates visual, vestibular, auditory, and somatosensory stimulation to promote neuroplasticity and more efficient neural processing. Improvements in vestibular symptoms, cognitive function, sleep quality, and overall quality of life suggest that OMST may exert broader regulatory effects on central nervous system integration and autonomic balance. As a structured, yet adaptable, non-invasive neuro-optometric intervention, OMST may represent a promising treatment option for patients with persistent post-concussive symptoms who have not fully responded to traditional therapies.
