Under sponsorship of the National Eye Institute, Barron Associates, Inc. is developing a “Dragon Vision” video gaming system for children with amblyopia or convergence insufficiency. Sustained game play over a prescribed therapy regime is intended to improve visual acuity in patients with amblyopia and positive fusional vergence in patients with convergence insufficiency. From September 2018 through January 2019, Barron Associates conducted usability testing of the software system with children 4-18 years old. Clinical trials involving 10 vision therapy providers and optometry practices around the U.S. will commence in April 2019. The included image can be viewed with anaglyph 3D glasses.
