What is Dyslexia?
The acquired form typically occurs if you have trauma or bleeding in the brain that affects the pathways involved in reading. If someone can’t read at all, we call that alexia. If reading is possible but labored, we call that dyslexia. For more information about this form of dyslexia, see our page on neuro optometric rehabilitation and brain injuries.
Developmental dyslexia is the type of reading disorder that children face when they have difficulty in learning how to read. It may surprise you to learn that it was an ophthalmologist (eye surgeon) by the name of Hinshelwood who originally focused attention on developmental dyslexia in a series of papers written in the late 1800s and early 1900s.
Most educators have shied away from using the term dyslexia, preferring instead to use terms such as specific reading disability.
- Dysphonesia – the auditory or phonetic type in which there is a disability in associating symbols with sounds. Phonemic awareness is poor.
- Dyseidesia – the visual type in which there are deficits in vision and memory of letters and word shapes limiting the ability to develop a sight word vocabulary. However they have the ability to acquire adequate phonetic skills.
- Mixed type combining features of the dysphonetic and dyseidetic.
Lately attention has been focused on the idea that developmental dyslexia is different pattern in the wiring of the brain that predisposes people to have talents or gifts in areas other than reading. Two prominent physicians, Brock and Fernette Eide, have written a book about the potential benefits and advantages of developmental dyslexia.

Visual Processing and Visual Efficiency
Signs of visual inefficiency include print wiggling, shimmering, ghosting, blurring, or doubling. This often results in fatigue, headaches, or loss of place when reading.
We always conduct a conference with the patient or parents to review our findings from the evaluation. If our evaluation shows that problems in visual efficiency or visual processing can account for key signs or symptoms that a patient is exhibiting, we customize a treatment plan.
This may consist of a prescription for lenses or prisms, or active optometric vision therapy. Targeted interventions include focusing, eye teaming and tracking, as well as visual perception.
Visual Crowding is a significant factor in visual dyslexia
The Vision & Learning Center
Before recommending visual intervention for dyslexia, we carefully look at how the eyes are taking in information when reading and compare that to how the visual areas in the brain are working together with language areas in the brain. That helps us to decide whether visual interventions are likely to be helpful and, if so, the areas in which to concentrate.
A conference is held after we complete our evaluation to review the results and to make recommendations for intervention if indicated.
