Binocular Vision Evaluation
A binocular vision evaluation is a visual examination that assesses how the eyes are working together. Individuals who benefit from a binocular vision evaluation may be experiencing double vision, eye strain, visual fatigue, and difficulties in school. This type of evaluation examines visual acuity, eye teaming, eye focusing, and eye movement.
A binocular vision evaluation differs from a routine eye exam in that a routine eye exam looks at visual acuities and the general health of the eyes whereas a binocular vision evaluation looks at how the eyes are working together. This is the reason why many children with visual issues may pass school vision exam. School vision exams only measure acuity and not the ability of the eyes to work together or the brain’s capacity to process what the eyes see.
Visual Perceptual Evaluation
A visual perceptual evaluation is a standardized comprehensive assessment of visual analysis and processing skills. This testing looks at the 17 skills that a person needs to read, comprehend and process information. At the Vision and Learning Center, we use the TVPS-4 (Test of Visual Perceptual Skills) that assesses the following areas:
- Visual Discrimination: the individual is asked to find the one image, in a field of five similar images, that exactly matches the presented target image.
- Visual Memory: the individual is presented with a target image for five seconds, is asked to remember it and then find the image, in a field of four images, on the following page.
- Spatial Relationships: the individual is asked to find the one image, in a field of five images, that is different from the rest.
- Form Constancy: the individual is asked to find the one image, in a field of four or five images, that matches the presented target image. The matching image may be larger, smaller, rotated, and/or embedded within a larger design.
- Sequential Memory: the individual is presented with an image of a sequence of elements for five seconds, is asked to remember it and then find the image with the same sequence, in a field of four images, on the following page.
- Visual Figure-Ground: the individual is asked to find a target image that is embedded in one of a field of four complex designs.
- Visual Closure: the individual is asked to match an incomplete target image to the correctly completed image in a field of four.
In addition, we also administer the Wold Sentence Copy Test, Gardner Reversals Frequency Test, DEM (Developmental Eye Movement) Test, and Auditory Processing Test.
