Vision And Visual Dyslexia book.

Explore visual dyslexia: reading difficulty resulting from vision related problems. Though dyslexia is primarily an auditory neurological processing issue, the qualities of visual input and the effects of visual processing also impact upon reading. Visual dyslexia is reading difficulty resulting from optical problems located in the eye or visual processing problems residing in the brain. The cause of visual processing problems is not known, but it can result from numerous visual stressors including lighting, word density and color.

The visual theory represents a traditional perspective of dyslexia, as being the result of a visual impairment . Reading, for example, requires the possession of both adequate vision and the neurological ability to process what is seen

The visual theory represents a traditional perspective of dyslexia, as being the result of a visual impairment creating problems when processing information from letters and words from a written text. This includes visual processing problems such as binocular, poor vergence, and visual crowding. The Visual Theory does not deny the possibility of alternative causes of dyslexia. Reading, for example, requires the possession of both adequate vision and the neurological ability to process what is seen.

These include blurred vision, visual field defects, and photophobia. Differential diagnoses include migraines, vertigo, and dyslexia. Treatment of BVD secondary to TBI. More subtle forms of visual impairments secondary to TBI include difficulty reading and tracking, poor depth perception, and poor hand-eye coordination. These visual impairments are all characterized by a failure of binocular vision, the ability for the two eyes to work together and present a single image to the brain. Visual functions which rely on binocular vision include: Convergence: the ability for the two eyes to focus in on a nearby object. Stereopsis: the ability to gauge depth and see in 3-dimensions.

Are dyslexia and vision problems connected? . Eye and vision problems don’t cause dyslexia.

Eye and vision problems don’t cause dyslexia. They are unrelated issues that may co-occur, meaning that a child can have both. Kids with dyslexia are no more likely to have eye and vision problems than other kids.

London: Whurr Publishers Lt. 2001. The goal of Dyslexia and Vision by Bruce J. W. Evans is to help teachers, psychologists, parents, and other professionals understand the relationship between vision and dyslexia. The author states that he is using an evidenced based approach to evaluate whether certain treatments would be beneficial for the dyslexia patient. For example, improving visual motor integration is not designed to improve decoding skills in reading; instead, it may help a child with copying and written work. I felt that the chapter should have had a more balanced view of management of learning related vision problems.
