Vision Therapy for Accommodative and Vergence DysfunctionTuesday, November 29th, 2011
Purpose of Technology
Vision therapy involves a range of optometric equipment, including lenses, prisms, and filters, and procedures, including occlusion, eye exercises, and behavioral modalities, that are used for eye movement and fixation training. The therapeutic goal of vision therapy is to correct or improve specific visual dysfunctions, such as accommodative and vergence disorders, amblyopia, and strabismus.
Questions addressed in this report include:
- Is vision therapy effective for treatment of vergence disorders?
- Is vision therapy effective for treatment of accommodative dysfunction?
- Have definitive patient selection criteria been established for vision therapy for the treatment of vergence or accommodative dysfunction?
These questions provide a framework for review and synthesis of the best available evidence, which is presented in this report, along with the Hayes Ratings for the technology. This report also provides background information about the condition being treated, a description of the technology, and the context for development of the technology. Other key elements addressed in the report include the regulatory status; applicable Medicare and commercial payer coverage policies; relevant ICD-9 and ICD-10 diagnosis codes; cost and cost effectiveness; credentialing; hospital length of stay; need for large case management; and ongoing and future clinical trials of the technology.
