We have struggled with this same issue and had to move to a new district, after we pulled them out of public school and sent them toa Montessori School for 5 years. It is hard. We had to this year after reentering the public school, legally force the school to give our gifted daughter, who also has a visual processing disability, an IEP. It took 6 months, lots of money and a war with the school. It is better now but it takes a certain kind of person to fight the entire school district.
