Visual Dyslexia in Children
Ophthalmology for Children: treatment of visual dyslexia and of difficulties in reading correctly and fluently
The Pediatric Ophthalmology Clinic also treats a fairly unknown disease which affects 3-4% of the school population (Italian Primary and Middle schools), namely, dyslexia: the difficulty in reading correctly and fluently. Dyslexic children can read and write but only by engaging their abilities and energy to the utmost. Since they cannot do it automatically they get tired quickly, make mistakes, are left behind and do not learn.
One of the fundamental components regarding correct and quick reading is the ability to differentiate letters in a short space of time. In the case of visual dyslexia, when textual perceptual distortions occur, such as bluriness (not correctable with visual lenses), movement of letters or words, sparkling on the page, difference in the spaces between words and lines interfering with reading, an optical correction can lead to improvements. The use of coloured lenses (haploscope photo-selective filters) help to resynchronise and change, in a dynamically balanced way, the wavelength of every colour of light that enters. The use of different colours effectively changes the speed of information in the neurological paths of those suffering from dyslexia, allowing for an improvement in the ability to read, write and understand. Therefore, surgical operations or medications are not concerned and there are no traditional risks linked to medical devices and procedures. It is a symptomatic treatment that in 50% of patients can improve ease of reading.
