Be happy this got picked up because this is one of the biggest things that cause learning disabilites in children. 80% of what we learn is taken in visually. If he has been this way for awhile and compensating his visual memory and some things may already be set up in his brain improperly. I would definately take him to a behavioral and developmental optometrist (COVD) and seek vision therapy and check for primitive reflexes. You cannot make binocular vision by patching an eye. You will acheive mono vision in each eye and get them both to 20/20 or close but they will never learn how to work together for higher order tasks and have true functional vision for the demands of academics and sports. I work with these children and every single one of them had some sort of visual impairment. Convergence insuffiency, fixation problems, amblyopia, this that and the other! It all leads to the same path. Motor coordination issues and cognitive challenges in school. PLEASE look on the website and find a COVD fellow located near you! I do vision therapy all day long with these children as well as auditory programs, reflexes and balance. There is never just one thing wrong because it all works togetehr in unison. It always involves other systems. If you do patch, do at least one hour of near work. Anything with eyes hands like coloring, painting, blocks, legos, building, games, cards, blowing activities to converge the eyes and things like that.
