Just curious what kind of eye doctor you are taking him to? How do they know he is suppressing vision in one eye?
My DS had a traumatic brain injury from an accident on New Years Eve (at age 5 1/2) which resulted in a sixth nerve palsy and almost total loss of tracking ability of his right eye for months. His right eye was stuck in the corner by his nose. He had to wear an eye patch on his good eye for 6 hours per day, and when he didn't have the patch, he had double vision at all times--so for instance he would see two TV's side by side or two books or two of every person. Strangely, we saw almost no change in his behavior or abilities. There may have been a small decrease in fine motor. He has developmental coordination disorder, so probably had some issues with sensory integration and visual tracking all along, but the results of the accident were extremely severe in terms of his vision, and his eyes were very obviously misaligned for months. He said that he liked having double vision and it didn't bother him. When he read, he said there were two books side by side and he just looked at one of them. I took him to a neuropsych who did the WISC IV. At the time this was done, his eye had started gaining some motion and was tracking past the mid-line but i don't think it was completely normal. His overall non-verbal IQ was 99.7 percentile, but he only got a 13 on block design, which is timed. The neuropsych attributed this to his poor fine motor skills. He scored below the 1st percentile on a timed pegboard test. One could argue he was scoring that low on the pegboard and block test because of his vision, which I guess is possible, but he scored really low for fine motor coordination before he was in the accident. I think he may have had issues with visual tracking before the accident though, too, but not nearly as severe. His processing speed I think was an 11 or 12, so slightly above average.
I took him for an OT and PT assessment and even though his eyes "look" normal now, rather than completely crossed, they say he can barely track moving objects at all. I don't know if this is from lingering effects of the sixth nerve palsy, or if he was always like that due to developmental coordination disorder or hypotonia. I have an appt. to take him to a neuro-opthamologist since the regular pediatric opthamologist thinks his eyes are completely normal now (despite what the OT and PT say). I'm hoping that a neuro-opthamologist will be able to tell me what's going on with the poor eye tracking and help him somehow. His depth perception is impaired and I'm hoping if he learns to track, it will help some of his fine motor skills and reading. I'm curious what vision therapy entails. I just thought I'd share that my son's eye was massively messed up, it happened very suddenly due to being in an accident, and it must have been hard for him sometimes wearing a patch and sometimes not, and looking at the world where everything was double, but it seemed to have little effect on him or his mood or behavior. Every once in a while he complained about getting a headache above one eye and he still does when he reads.
