Abstract
Aim: With this case study, we hypothesize that identical concomitant symptoms exist between ASDs and Meares-Irlen Syndrome, determined by the level of visual stress. Method: A questionnaire was given to subjectively identify the type and degree of symptoms associated with visual perception, and if these symptoms disrupted quality of life and learning process. This questionnaire was composed of questions on visual symptoms such as: symptoms linked to near and far visual distortion, binocular visual dysfunction and reading or writing errors experienced by the patient. Results: This patient experienced a significant reduction in visual stress symptoms when wearing color-tinted lenses (p <.0001). With respect to our hypothesis, it appeared that treating the Meares-Irlen Syndrome with the color-tinted lenses, (1) improved the patient’s analysis of visual signals, and (2) reduced sensory hypersensitivity. Conclusion: In this case study, it appeared that certain ASD deficits might have been caused by Meares-Irlen Syndrome, notably a change in the integration of sensory data. We wanted to highlight the lack of Meares-Irlen Syndrome screening, which occurs because of a general unawareness of the syndrome. It is important to find ways to reduce this unawareness by developing the skill sets of different professionals in terms of adult ASD evaluations and consultations, by offering a scientific and holistic approach toward ASD individuals and by not excluding the possibility of an underlying Meares-Irlen Syndrome.
Highlights
Meares-Irlen syndrome was formerly known as the Syndrome of Scotopic Sensitivity [1]
It is a cluster of symptoms related to a neurological impairment in the processing of certain wave lengths contained in light [2] and it is considered a disorder of the magnocellular system causing a visual handicap as well as visual deformation and visual stress
With respect to our hypothesis that this Autism Spectrum Disorders (ASD) patient was subject to Meares-Irlen syndrome, it appeared that the syndrome was alleviated through the use of color-tinted lenses and gave the patient (1) a better analysis of visual signals, (2) a decrease in sensory hypersensitivity
Summary
Meares-Irlen syndrome was formerly known as the Syndrome of Scotopic Sensitivity [1] It is a cluster of symptoms related to a neurological impairment in the processing of certain wave lengths contained in light [2] and it is considered a disorder of the magnocellular system causing a visual handicap as well as visual deformation and visual stress. It engenders difficulties in reading through the hyper-transmission of a specific light wave [3]. This study, which was conducted on adult university students, showed a 21% improvement in reading speed when using color-tinted lenses, suggesting that these lenses provide a positive benefit
