Over Thirty Years of Vision Therapy Success
The vision therapy department has been an established part of EYEcenter for over thirty years. We receive referrals from many professionals, including optometrists, physicians, psychologists, educators and rehabilitation specialists for the diagnosis and treatment of conditions in the following areas: eye muscle weaknesses including tracking, eye alignment and focusing; visual information processing; and vision-related learning issues.
Common symptoms of these types of disorders:
- Smart in everything but school
- Frequently loses place or skips words when reading
- Squinting, eye rubbing or excessive blinking
- Headaches, dizziness or nausea after reading
- Short attention span
- Fatigue, frustration or stress doing schoolwork
- Labeled dyslexic/ADD/behavioral problem
- Poor reading comprehension or fluency
- Difficulty copying from the board
- Double vision/images go “in and out” of focus
Treatment may consist of any or all of the following: glasses, contact lenses, patching, in-office therapy, home therapy (using lenses, prisms, filters, and a computer program), or an outside referral to another health care or special education providers. If treatment is required, a customized program is designed to address the specific inadequacies measured. Upon completion of the program, any areas addressed are post-tested and a final report is generated, including the measured results of the therapy and any further recommendations.
Vision & Learning
My Child is Near-Sighted, Will Glasses Correct His/Her Learning Problem?
There is controversy in the exact relationship of vision to learning. For example there is a negative correlation between distance refractive error in reading ability. Myopic or nearsighted children who cannot see clearly at a distance without the glasses are more commonly good readers. Chinese and Jewish children have an exceptionally high incidence of nearsightedness and tend to read a lot. Children who spend tremendous amounts of time reading become nearsighted. People who live on submarines for long periods of time become nearsighted. Before Alaska became a state myopia was rare. After becoming a state, more than 50 percent of the children in Alaska developed near-slightness. Thus, correlation is such whereby nearsightedness or poor distance vision is highly correlated with success in reading. Restated another way, poor distance vision is associated with better reading abilities. Farsighted children statistically are poorer readers than myopic children.
What is the Relationship Between Eye Muscle Problems and Learning?
Some of the mechanical visual skills which are related to reading include focusing or accommodation, eye teaming or convergence. Fatigue of one or both the systems may interfere with reading. There is also a relationship between eye movement skills such as saccadics (whereby we change fixation from one target to the next) and smooth following movements known as pursuits and reading. Children who cannot make accurate eye movements are often found to skip lines and words while reading.
The visual system was originally designed so that the peripheral vision was responsive to motion detection (danger from the jungles) with a central portion for fine discrimination (to identify the source of danger e.g., a lion. In the school environment the child is expected to ignore the peripheral portion of their visual system and pay attention with the central portion. If the child can not ignore the peripheral portion he/she becomes distracted. Improvement in eye movement skills often results in less distraction and fewer errors of skipping words while reading.
My Child Loses His/Her Place, Is That Related to the Eyes?
Reading requires very accurate saccadics which are fixations from one spot to another. A second type of eye movement which involves tracking is, also, related to attention and reading. Children who have poor eye movements are easily distracted and loose their place. Remember, the eye movement system was designed so that peripheral vision detects motion and danger. Imagine what happens when the system works correctly in the class room. As soon as there is peripheral movement the eyes move towards the source of movement. This results in the complaint of inattention. Thus, reflexive eye movement skills must be socialized so that they do not respond reflexively to peripheral information. In addition, speed and accuracy must be trained so that one does not loose ones place.
The skills are easily improvable with vision therapy (See testimonial for patient comments). Once the information is brought into the eyes it must be sent back to the brain for appropriate processing. The information must be utilized and integrated with the sensory and motor areas of the brain. Defects in the perceptual (interpretation of visual system) and motor (the integration with output, e.g., hand-eye coordination) may interfere with the reading process. Perceptual motor skills are key in the early acquisition of reading skills. A deficit is important to identify at a very early age, i.e., five to seven years of age. Remediation of the skills at a later date, such as age 12, will be less effective on reading. Thus, early identification and treatment is essential. It is evident that there is more to good vision than 20/20.
My Child Reverses Letters and Words, Does He See Backwards?
It has been presumed that children who reverse letters or words see them backwards. This is false. They have directional confusion. In the real world direction has no meaning. For example, a chair is a chair no matter which way it is placed. Changing direction does not change interpretation. In the world of language direction changes meaning. Connect the bottom of a chair and it looks like a “b”. Turn it 180 degrees it becomes a “d”, flip it upside down and it becomes a “q” and flip it again it becomes a “p”. Thus, direction changes meaning. The difference between “was” and “saw” is direction.
What Are The Other Visual Components Necessary for Academic Achievement?
As mentioned previously we should correct all optical errors of the eyes (glasses); eliminate eye muscle problems; create smooth accurate eye movements. In addition, we should make sure that we properly interpret what we see and use it appropriately. These are known collectively as perceptual skills and include form perception, size and shape recognition, visual memory, visual motor integration, e.g. hand-eye coordination.
Is There More That I Should Know About Vision and Learning?
Yes. More information may be obtained on vision and learning by clicking here. An excellent resource for motor development of visual skills is Wisconsin Achievers which has a series of workbooks designed to improve gross motor, fine motor and visual perceptual development. We strongly encourage the use of these workbooks to supplement your vision therapy.
Vision and Learning problems are handled by Dr. Randy Fuerst, Dr. Matt Earhart, and Dr. Brenda Coen. For further information you should schedule a visit with one of these three doctors.
