Scientists May Have Found the Real Cause of Dyslexia—And a Way to Treat It

A bold headline for a study containing 60 subjects but this does make interesting reading. Many thanks to VW for pointing me in this direction.

In essence, they noticed that there are physiological differences inside the eye between subjects with and without dyslexia:

Just as most of us have a dominant hand, most have a dominant eye too, which has more neural connections to the brain. The study of 60 people, divided evenly between those with dyslexia and those without, found that in the eyes of non-dyslexic people, the arrangement of the cones is asymmetrical: The dominant eye has a round, cone-free hole, while the other eye has an unevenly shaped hole. However, in people with dyslexia, both eyes have the same round hole. So when they're looking at something in front of them, such as a page in a book, their eyes perceive exact mirror images, which end up fighting for visual domination in the brain. 

They go on to use a special lamp which helps to eradicate the problem.
