|What is Vision Therapy|
Vision therapy, (also known as orthoptics, vision training, visual training, eye training) is an organized therapeutic regimen utilized to treat a number of neuromuscular, neurophysiological, and neurosensory conditions which interfere with visual function. Vision therapy encompasses a wide variety of procedures to improve a diagnosed neuromuscular, or neurophysiological visual dysfunction. The treatment can be relatively simple such as patching an eye as part of amblyopia therapy, or it may be complex involving sophisticated instrumentation and computers.
Vision therapy usually involves a series of treatment visits during which carefully planned functional activities are carried out by the patient under close supervision in order to relieve the visual problem. The specific activities and instrumentation are determined by the nature and severity of the condition. The frequency and duration of treatments are dictated by the individual situation, although established guidelines are available suggesting appropriate length of therapy for various diagnoses.
When Is Vision Therapy Necessary?
Most vision problems can be very easily corrected with eyeglasses. In fact about 80-90 percent of the vision problem we detect can be treated with glasses or contact lenses. However, approximately 15-20 percent of the population with symptoms of blurred vision and eyestrain have vision problems that cannot be treated successfully using glasses alone. It is this group of people that need vision therapy. Vision therapy is generally required to treat problems of binocular vision, accommodation, ocular motility, amblyopia, strabismus, and visual information processing. Individuals with these problems experience eyestrain when reading or doing other close work, inability to work quickly, sleepiness, inability to attend and concentrate, double vision, and loss of vision. Even more significantly, children with amblyopia and strabismus face the possible loss of vision if an appropriate vision therapy program is not initiated in a timely fashion. Children with visual information processing problems may have difficulty learning.
Is Vision Therapy Effective?
There is extensive clinical and scientific support for vision therapy as a treatment modality. Much of this support is in the optometric literature since most of the development of vision therapy has been done by optometrists. An excellent review of the literature on the effectiveness of vision therapy is available from the American Optometric Association (AOA). You can obtain a copy by contacting the AOA at 243 N. Lindbergh Ave, St. Louis, MO. 63141, 314-991-4100.
The prognosis for all accommodative (focusing) and non-strabismic binocular vision (eye teaming) problems is excellent (85%-95% success). In recent years there have been several studies that have reviewed success rates for various types of accommodative and binocular disorders. These studies clearly demonstrate the efficacy of vision therapy for these conditions.
