Thanks for your comments. I now think my son has a Visual Processing Disorder. The descriptions of a few of the sub-sections are right on for him:

and explains why I have heard so many times that he either has ADHD or or a severe sensory problem. Two years of OT did not help him very much because I know think the symptoms rather than the cause were being addressed. We are going to give vision therapy a try.
The testing by the behavioral optometrist revealed that he processes visually information very slowly (5%) and his WISC IV scores backs this up (GAI 99% with Processing Speed of 16%).
He struggles with writing, spelling and quick math computations. I am hoping for accommodations from the school and help with his writing. I am going to request that the school complete a full evaluation as well as have a private evaluation completed.
My husband thinks he struggled with these issues also, but the classroom was much less visually demanding 40 years ago.
