Concussion & Visual Processing: A Promising New Study on Rehabilitation
Recent research published in the journal Brain Injury highlights the potential benefits of targeted visual rehabilitation programs for individuals experiencing visual processing difficulties following a concussion. The study followed a cohort of patients with persistent post-concussion symptoms, focusing on deficits in binocular vision, accommodation, and eye movements. Researchers found that a structured program incorporating vision therapy exercises and prism lenses led to significant improvements in visual function, reduction in headaches, and improved overall quality of life. This research reinforces the importance of comprehensive visual assessments after a concussion and the potential for vision therapy to play a crucial role in recovery. It also emphasizes the interconnectedness of vision and cognitive function after head injury.
Visual Snow Syndrome: Exploring the Link with Migraine
A new meta-analysis, presented at the European Headache Federation Congress, sheds further light on the co-occurrence of Visual Snow Syndrome (VSS) and migraine. The analysis examined data from multiple studies and confirmed a strong association between the two conditions. While the exact nature of the relationship remains under investigation, the research suggests shared neurological pathways and potential mechanisms. Understanding this link could lead to more effective diagnostic and therapeutic strategies. Importantly, the authors advocate for a holistic approach to managing both conditions, considering the impact of visual symptoms on migraine frequency and severity, and vice versa. We continue to follow any updates and research as it becomes available.
Visual Stress & Reading Speed: Investigating the Role of Coloured Overlays
Researchers at the University of Cambridge have published a pilot study exploring the immediate effects of coloured overlays on reading speed and comprehension in children diagnosed with dyslexia. While previous research on coloured overlays has yielded mixed results, this study aimed to control for several confounding factors, including the type of text used and the specific colour of the overlay. Initial findings suggest that, while not universally effective, certain individuals with dyslexia experience a statistically significant improvement in reading speed with specific colour combinations. This emphasizes the need for individualised assessments to determine the potential benefits of coloured overlays and the importance of a multimodal approach to addressing reading difficulties. It also cautions against a ‘one size fits all’ approach and highlights the potential for targeted interventions based on individual needs.
Optometry & Myopia Management: Updated Guidelines for Practitioners
The Association of Optometrists (AOP) in the UK has released updated guidelines for myopia management in children and adolescents. These guidelines provide practitioners with evidence-based recommendations on the assessment, monitoring, and treatment of myopia, including information on the use of orthokeratology, multifocal contact lenses, and low-dose atropine. The revised guidelines emphasize the importance of early intervention to slow the progression of myopia and reduce the risk of long-term visual complications. They also stress the need for shared decision-making with parents and children, ensuring they are fully informed about the benefits and risks of different treatment options. This is a valuable resource for practitioners dedicated to providing the best possible care for young patients at risk of, or experiencing, progressive myopia. We encourage all optometrists to review the updated guidelines for optimal patient care.
