(BBC News) — 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 a small study they found that most dyslexics had dominant round spots in both eyes – rather than in just one – leading to blurring and confusion.
UK experts said the research was “very exciting” and highlighted the link between vision and dyslexia.
But they said not all dyslexics were likely to have the same problem.
People with dyslexia have difficulties learning to read, spell or write despite normal intelligence.
Often letters appear to move around and get in the wrong order and dyslexic people can have problems distinguishing left from right.
Human beings have a dominant eye in the same way that people have a dominant left or right hand. (…)
