The Canadian Association of Optometrists Vision Therapy Position Statement from February 2017 is below:
Background of Vision Therapy
Vision therapy and rehabilitation is a prescribed, individualized treatment plan designed to develop, correct, improve, or rehabilitate specific dysfunctions of the vision system.
It includes the treatment of ocular motility dysfunctions; non-strabismic binocular disorders (eye teaming disorders); strabismus (misalignment of the eyes); amblyopia (a form of suppression that can lead to poorly developed visual acuity in one or both eyes); accommodative disorders (focusing problems); and visual information processing disorders, including visual-motor integration. Vision therapy and rehabilitation may also be effective in the treatment of eye and vision problems related to traumatic brain injury.
Vision therapy and rehabilitation programs typically involve guided, structured eye activities and the use of therapeutic or performance lenses, prisms, filters, occluders, specialized instruments, low vision devices, and/or computer programs. The course of therapy may last weeks to several years, depending on the nature and severity of the deficit(s), and will include regular intermittent monitoring by the supervising optometrist.
