Visual Information Processing Evaluation
If a person’s visual skills are not adequately developed or impaired by a traumatic brain injury such as a motor vehicle accident or head injury, vision problems may occur.
Vision is more than clarity (20/20 on the eye chart). It is a complex combination of learned skills such as…
- Tracking - the ability of the eyes to move smoothly across a printed page or while following a moving object.
- Fixation - quickly and accurately locating and inspecting a series of stationary objects, such as words while reading.
- Focus change - looking quickly from far to near and back without blur.
- Depth Perception - judging relative distances of objects-how far or near they are.
- Peripheral Vision - monitoring and interpreting what is happening in the surrounding field of vision.
- Binocularity - using both eyes together as a team-smoothly, equally and accurately.
- Maintaining Attention - keeping focused on a particular activity while interference, such as noise, is present.
- Near & Distance Acuity - clearly seeing, inspecting, identifying and understanding objects viewed at various distances
- Visualization & Memory - accurately picturing images in the "mind's eye," retaining and storing them for future recall
- Vision perception - understanding what is seen
Depending on patient history, signs, symptoms and/or the review of prior diagnostic evaluations, an independent assessment is recommended to evaluate and diagnose specific eye or vision problems.
If this assessment is being recommended for you or your child, it is likely your optometrist/teacher/OT is suspecting that an underlying visual problem may be interfering with yours or your child’s ability to learn, read, comprehend and pay attention.
