What is Visual Dyslexia ?

The term Visual Dyslexia, has long been the subject of controversy. The American Academy of Pediatrics state that most experts believe that dyslexia is a language based difficulty. The symptoms of visual problems often mimic some of those found within dyslexia, however visual problems are not the cause of dyslexia. This is why we refer to visual dyslexia more accurately as Visual Processing Difficulties.

Visual Processing Difficulties refers to a reduced ability to make sense of information taken in through the eyes. This is very different from problems involving sight or sharpness of vision.

The most common types of Visual Processing Difficulties are Meares- Irlen, Wandering Eye, Lazy Eye and Convergence Insufficiency. Meares-Irlen is a photosensitive condition that affects the visual cortex and hinders reading. It is scientifically known as ‘Visual Stress’ or ‘Pattern Glare’, and Scotopic Sensitivity Syndrome. Wandering Eye, also known as Strabimus, is a condition is which the eye does not properly align with each other when looking at an object. Learners may have difficulties with depth perception and or double vision. Lazy eye is a disorder in which an eye fails to achieve normal clarity of vision, even with prescription eyeglasses or contact lenses. If left untreated, blindness can occur. Convergence Insufficiency is a condition in which your eyes are unable to work together when looking at nearby objects. This condition causes one eye to turn outward instead of inward with the other eye creating double or blurred vision.

At PECM, we are incredibly fortunate to have a Visual Processing Clinic, where we can ascertain the difference between visual processing and perceptual disorders and/or dyslexia. Our clinician is trained in the use of the Lawson Anti Suppression Device, used in the treatment of visual disorders and also bring over forty years of experience as an early years teacher.
