My son who is now 33 years old was born with eye problems....had squint eyes and 2 surgeries when he was a baby.....he has no vision in one eye and the good eye is now damaged also....I always thought when he was little that his behavior was affected by the eyesight....but never persued this since he was a very smart little boy....around 14 years old he changed a lot...and became what I felt was bi polar....he has had problems off and on for years now....I often still wonder if the eye problems did not affect this.....now I am reading all kinds of things which no doubt have been connected....interesting that all of this has now come to light....
