Treatable dyslexia?

“French scientists say they may have found a potential cause of dyslexia which could be treatable, hidden in tiny cells in the human eye… In the study, scientists looked into the eyes of 30 non-dyslexics and 30 dyslexics. In non-dyslexics, they found that the blue cone-free spot in one eye was round and in the other eye it was oblong or unevenly shaped, making the round one more dominant. But in dyslexic people, both eyes had the same round-shaped spot, which meant neither eye was dominant. This would result in the brain being confused by two slightly different images from the eyes. Researchers said this lack of asymmetry might be the biological and anatomical basis of reading and spelling disabilities. For dyslexic students, their two eyes are equivalent and their brain has to successively rely on the two slightly different versions of a given visual scene.” What do you think about this study? http://www.bbc.com/news/health-41666320
