I have a son that tested gifted verbally.
Please read my thread at 'need help with scores' to see all his scores. He had processing issues that brought down his overall Full Scale IQ.
He has strabismus/vision problems and had eye surgeries and vision therapy in the past. He just turned nine and is going into a full time gifted program in 4th grade.

I just took him for extensive testing by an optometrist who specializes in vision therapy. My son's testing came back with some interesting results. The doctor tracked his eyes with a visiograph to calculate speed, jumps, missed words, eye tracking etc. My son then took a test on what he read to get a comprehension score. His scores rank him reading at 11th grade level with the speed of a 13th grade level (college!) person. His comprehension is 90%. He is having all kinds of trouble with eyes, tracking, jumping, missing words etc. The doctor told me he was very surprised at how well my son has compensated for his lack of ability to use two eyes at the same time and that it was unbelievable what he was able to do, even though he is rapidly turning one eye off and then the other, alternating between eyes as he reads. His comment was 'Imagine where he would be on the testing if he could see properly.' His processing speed was absolutely horrible on the tests, but in reading he still was phenomenal.

My question is...
Do you think my son could actually be remarkably more gifted than what he shows, even though he is already technically gifted? I would hate to not really know how gifted he really is. I am concerned about missing the big picture due to lower overall IQ. Does anyone have any advice or ever seen or heard of anything like this?
