We did VT with our dd10, two years ago. I agree with the above poster. It was not a cure all nor the panecea for visual issues, but it helped our daughter with her visual tracking and her eye teaming skills. Additionally, doing these exercises allowed us to find her focal seizures! Getting the seizures under control has been a huge part of her doing better in school, however she is still dyslexic. That issue will be an ongoing source of issues with school.
