Welcome to Calgary's only neuro-cognitive optometric and perceptual learning clinic, Calgary Vision Therapy. Providing Developmental Optometry services, Dr. Brent W. Neufeld started Calgary Vision Therapy to help you achieve your potential. Did you know that over 80% of all the information that reaches your brain is through the visual system? If your visual system is not working efficiently, your achieving potential may be limited. Having 20/20 sight does not mean that your vision is fine and that your vision has nothing to do with your perceptual or learning difficulties. Intensive in office optometric vision therapy will help improve most visual skills.
• Learning Difficulties often have many factors involved. Too often only 20/20 sight is checked and that is equated with having good visual skills. Dr. Neufeld and Calgary Vision Therapy spends significant amount of time probing different ways that we should be able to use our visual system effectively to allow the individual to have the best opportunity to learn, retain and recall information.
• When there are areas of visual skill or visual perceptual dysfunction, rather than avoiding this difficulty and forcing the individual to use less efficient skills to try to accomplish the same task, we provide vision therapy services to help the individual learn and improve those poorly developed skills.
• The CITT study has shown that office based vision therapy is the most successful treatment modality for convergence insufficiency.
• Convergence insufficiency is a binocular coordination dysfunction where the individual is not able to control and team their eye movements when looking at an object within arms reach. Some individuals may be able to look at a close object ("look near") and their eyes may look like they are pointing towards the correct location, but they are unable to sustain that visual posture or they are not able to consistently achieve that visual posture after looking away and then back to the close object.
• An individual with convergence insufficiency will often see double when viewing objects within arms reach, or will cover/close an eye when reading, or will see movement in text when reading.
• There are many additional eye teaming difficulties that directly impact an individual's ability to perform up to their potential. Some of these eye teaming difficulties may require office based vision therapy to remediate their difficulties; however, some of these eye teaming difficulties may be managed by lenses or prism glasses.
• Basic eye exams may not test for many of these eye teaming difficulty problems. However, there are several optometrists who test for these eye teaming difficulties and then refer to our office to initiate treatment as Calgary Vision Therapy is the primary center exclusively offering vision therapy services in Calgary.
• An individual who has 20/20 sight can still have a focusing problem. (See The 20/20 myth). Although an individual may be able to see small text, it is possible that this same individual may not be able to sustain the clarity of the text for longer than a couple minutes. Alternatively, he/she may not be able to quickly clear text when he/she shifts their visual attention from one location to another, for example copying notes from the smart board.
• Specific learning lenses may be prescribed when found valuable. In may cases, office based vision therapy can improve these deficient visual skills.
• Visual perception is how the brain interprets what we see.
If the information going into the brain is being garbled, it is much more difficult to make sense of what is seen. A child having difficulty with persistent letter reversals, struggles with remembering words they have just read/learned or math/reading problems may have a visual information processing delay.
• Standardized tests are performed to determine areas of visual information processing / visual perceptual weakness. One significant difference is, in the case where a visual perceptual delay was determined, instead of avoiding the area of delay (to make the problem 'go away'), Calgary Vision Therapy prefers to provide the opportunities to develop the missing/delayed visual skill whenever possible.
• When one reads the English language, it is important that one is able to follow the text accurately from left to right and top to down. A child who has not developed this skill efficiently will need to put in an exorbitant amount of effort in the mechanical movements required for reading. This reduces efficacy, comprehension and reading speed.
• Dr. Neufeld and Calgary Vision Therapy uses normed tests not performed in basic eye exams and uses the ReadALyzer machine to determine, demonstrate and compare eye tracking abilities.
• It was once thought that amblyopia, one type of lazy eye, was untreatable after the age of 6 or 9 years of age. Studies done in neurology have shown over the last 10 years that the brain is plastic and changes can be made even into adulthood. Patching the 'bad' eye was the primary treatment in the past. Calgary Vision Therapy utilizes newer techniques and equipment to help stimulate vision development.
• Some individuals who have turned eyes (in turns or out turns) can gain better control of their eye coordination.
Dr. Neufeld performs additional testing to determine the potential for improvement in binocular coordination and reduction of strabismus through intensive office based
• Had an eye surgery for strabismus already and the eye is turning back again? In some cases, it turns back because the brain has not learned how to use the eye in the new surgically created position. Vision Therapy should be considered as a management tool post surgery (should surgery be a previously decided option).
• Athletes require efficient visual abilities to be able to perform at their peak performance ability. Some athletes are naturally gifted with great agility and athleticism. These athletes can get away with less efficient visual skills and rely more on their finesse. They can even perform to a high level in spite of their less than optimum visual skill abilities.
• Looking for another advantage in developing your sports performance? Sports Vision Training may be for you. Even a slight improvement in eye-hand coordination, eye teaming, eye tracking, eye focusing, or peripheral awareness may provide you that sports performance edge you need.
• Each sports visual training program is custom tailored for each sport and for each athlete. Emphasis will be place on the visual skills required to achieve peak athletic performance.
