DESCRIPTION
The goal of vision therapy is to improve or correct diagnosed visual dysfunctions. Vision therapy includes a wide range of nonsurgical optometric treatment modalities. Modalities include eye exercises, flashing light response exercises, prisms, wearing tinted or colored lenses, filters, occluders, specialized instruments, computer programs and other devices.
Vision therapy programs vary on the techniques to be utilized, length of training and scheduling and timing of therapy. The program is specific for the individual.
POLICY
Vision therapy for the treatment of all visual dysfunctions is considered investigational.
ADDITIONAL INFORMATION
Vision therapy is also known as vision training, visual therapy, optometric vision therapy, orthoptics - eye exercises, orthoptic vision therapy, and syntonic optometry.
Vision therapy is often requested for individuals with the following visual dysfunctions:
Accommodative disorders - focusing problems
Amblyopia - lazy eye
Ocular motility dysfunction - eye movement disorders
Strabismus - misalignment of the eyes
Treatment of learning disabilities - particularly reading disorders including attention deficient disorder dyslexia, dysphasia or other reading disorders
Vergence dysfunction - inefficiency in using both eyes together
Visual rehabilitation after traumatic brain injury or stroke
There is a lack of available evidence in peer-reviewed literature to support the effectiveness of vision therapy. It cannot be determined whether improvement with vision therapy is attainable outside investigational settings.
Vision therapy does not meet the following technology evaluation criteria:
The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes.
The technology must improve the net health outcome.
The technology must be as beneficial as any established alternatives.
The improvement must be attainable outside the investigational settings.
