A typical vision therapy session will include exercises that make use of lenses, filters, prisms, occluders, and computer devices aimed at developing visual and information processing skills.
Vision therapy (VT) works based off of the scientific principles of neuroplasticity. Neuroplasticity is the ability of neurons in the brain to change their connections and behaviors in response to new environments. This means that neuroplasticity allows you to create neural pathways every time you learn or do something new.
For example, an eye that is amblyopic (or “lazy”) is receiving imbalanced visual input compared to the stronger eye, which can lead to imbalanced neural processing and visual deficits. VT works on strengthening the neural connections between the brain and the eyes by creating new visual environments for the brain to develop new neural connections. The more we perform these activities, the more intrinsic these new neurological pathways become.
VT sessions are usually 45 minutes long once per week in office, with 10-15 minutes of assigned daily exercises to be done at home. A VT program usually lasts a minimum of 3 months to 6 months depending on the diagnosis and patient compliance.
