Perceptual Testing: Perceptual testing is needed to evaluate all of the visual skills required to succeed in reading, writing, and throughout life. Perceptual testing is ordered as determined by our doctors to evaluate the patient’s abilities to visually discriminate, utilize visual memory and visual sequential memory, recognize form constancy, effectively and efficiently evaluate visual-spatial relationships, as well as assess visual figure-ground and visual closure among objects in space. Perceptual testing helps to point out what aspects of therapy are most needed.
Visual Closure is the ability to visualize a complete whole when given incomplete information or a partial picture. This skill helps us understand things quickly because our visual system doesn't have to process every detail to recognize what we're seeing. Where we're reading, this skill helps us recognize sight words.
Visual Figure-Ground is the perceptual skill that lets us pick out details without getting confused by the background or surrounding images. This skill is especially helpful when we're presented with a lot of visual information at one time.
Visual Discrimination lets us see differences between objects that are similar. Good visual discrimination helps keep us from getting confused. For example, when we read, it is visual discrimination that lets us see the "was" and "saw" are different even though they have the same letters.
Visual Memory is another important perceptual skill. It helps us recall what we've seen. Children who do better when the question is read to them versus when they read is one example of a visual memory problem. They can’t remember what they read therefore they can’t answer the question!
Form Constancy is the ability to mentally turn and rotate objects in our minds and picture what they would look like. This skill helps us distinguish differences in size, shape, and orientation. Children with poor form-constancy may frequently reverse letters and numbers.
The Visagraph® is an eye-movement recording device and is the result of more than 80 years of foundational studies in conjunction with leading research on reading. Data collected with the Visagraph® provides a unique insight into each student’s silent reading behavior, revealing what may be hindering independent reading development. We do the Visagraph test with every vision and learning evaluation to get a better understanding of how the patient’s eyes move while reading in order to help determine the appropriate therapy to be implemented at the beginning of testing.
How We Structure Vision Therapy: Vision Therapy is offered in the office one day a week for 45 minutes. During this session, the patient works one on one with a vision therapist performing a variety of tasks designed to help improve the performance of their visual system. Home therapy is given and expected to be completed daily outside of the weekly therapy sessions within the practice. We are equipped to handle children with learning disabilities including children who are autistic and children who have Down's Syndrome.
