Many, many thanks to Dr. Dom Maino for his blog post. He has started with Dr. Len Press’ article and then expanded on additional literature.
The info below is from Dr. Maino.
QUESTION 1:
Where is the scientific basis for Optometric Vision Therapy?
ANSWER 1:
As mentioned, Dr. Cooper’s scholarly article provides references that clearly substantiate the scientific basis of vision therapy. Clinical Practice Guidelines
are available from the American Optometric Association on the Care of the Patient with Learning Related Vision Problems, Accommodative and
Vergence Dysfunction, Amblyopia, and Strabismus. Each of these has references incorporating scientific method. The research presented is commensurate with clinical research in fields such as occupational therapy, and is equal to or better than research traditionally presented for clinical methods in pediatric ophthalmology.
[ I would also add the outstanding article by Dr. Kenneth Ciuffreda’s article:The scientific basis for and efficacy of optometric vision therapy in nonstrabismic accommodative and vergence disorders.]
QUESTION 2:
How do optometrists know which patients might benefit from vision therapy?
ANSWER 2:
The Four Clinical Practice Guidelines from the AOA mentioned above provide clear guidelines for differential diagnoses. Textbooks referenced in this
article, in addition to others available, provide this as well.
[AOA Guidelines: Pediatric Eye And Vision Examination , Care of the Patient with Amblyopia, Care of the Patient with Strabismus, Care of the Patient with Accommodative and Vergence Dysfunctions,Care of the Patient with Learning Related Vision Problems.]
QUESTION 3:
Is it true that vision therapy patients are “in for life?”
ANSWER 3:
Nothing could be further from the truth. The clinical practice guidelines above, in addition to guidelines issued by the College of Optometrists in Vision Development (COVD) based on ICD codes for various conditions, are proof that this is not the case.
QUESTION 4:
How might I judge if a patient is in need of vision therapy, or if a person I am referring the patient to is a credible provider?
ANSWER 4:
All optometrists receive graduate education in and are licensed to practice vision therapy. The Optometric Extension Program (OEP) providespost-graduate education in the areas encompassing vision therapy. The Collegeof Optometrists in Vision Development (COVD) provides a board certification process, and has a national directory of providers. The American Academy of Optometry (AAO) has a diplomate program in binocular vision and perception as well as in pediatric optometry.
QUESTION 5:
Why is vision therapy so expensive?
ANSWER 5:
It is intriguing that physicians don’t ask the same questions regarding the expense, scientific underpinnings, and pertinence to learning of occupational therapy, which they endorse far less critically, despite the obvious parallels between the two fields. To answer the question directly, the fees for vision therapy services are commensurate with other therapy procedures involving similar bodies of knowledge and time expended. Aside from the doctor’s time in evaluating the patient, there are often prior reports to read that are pertinent to decisions about optometric intervention, time spent programming and sequencing activities to strike an effective balance between office and home therapy, and time spent with therapists to discuss ongoing progress.
QUESTION 6:
Why does vision therapy work when it does? Eye problems shouldn’t have anything to do with LD or ADD since these are CNS or brain problems.
ANSWER 6:
The retina is brain tissue. Dissociating the role of the eye in visual processing from brain function is an artificial distinction. With regard to learning and attention systems, principles of cognitive neuroscience substantiate that interventions directed toward sensory and motor eye functions have a salutary and pervasive effect on central processes of the brain.
[A paper by pediatric ophthalmologist Dr. David Granet, disputes the claims that ADD and vision are not related. He notes that “…We report an apparent three-fold greater incidence of ADHD among patients with CI when compared with the incidence of ADHD in the general US population (1.8-3.3%). We also note a seeming three-fold greater incidence of CI in the ADHD population….”]
