Post Stroke/Brain Injury Workup
The Post-Brain Injury Vision evaluation is a two to three hour assessment. The testing included is determined by the history of the brain injury, and may include some or all of the other special testing described above. It is very common for patients to be unaware of their vision and visual processing deficits following brain injury, so we typically test all of the following areas:
- Eye examination—are glasses needed; are the eyes healthy; are the eyes tracking and focusing correctly at near; and are the eyes working together as a team
- Peripheral vision
- Spatial awareness and visual affects on balance—sometimes special prisms can be worn to help with balance and walking
- Visual-motor skills
- Visual memory
- Visual form perception and visual perceptual speed
- Contrast sensitivity—are the patient able to see in dim lighting and or foggy conditions
- Intuitive Colorimeter test to see whether specialty tinted lenses will help with comfort and any feelings of dizziness or disorientation
Intuitive Colorimeter Testing
The Intuitive Colorimeter is used to sample across the color spectrum to find specific wavelength filters (tints) that alleviate or reduce symptoms for patients. Research has demonstrated benefit for difficulties involving visual neurophysiology, including some types of the following: migraine, epilepsy, reading disorder, and post brain-injury symptoms. An intake vision evaluation for eyeglasses prescription, eye teaming, and focusing is required to write a prescription for Intuitive Colorimeter filters. Intuitive Colorimeter testing is included in our Visual Information Processing workup.
Yoked Rehabilitation Prism Testing
Yoked rehabilitation prism can improve balance and coordination in many patients. Frequently patients who “toe walk”, veer, run into things on one side, or lose their balance will benefit from having special prisms ground into their glasses to restore a normal perception of visual straight ahead.
Visual Evoked Potential Testing
Visual Evoked Potential testing can be done to examine the brain response to simple visual stimuli, such as checks or gratings. It can be used to estimate visual acuity (the level of detail vision) in patients who are unable to otherwise respond or who need objective evidence of vision for legal purposes. It is also used for other applications to examine the health of the pathway of each eye to the primary visual cortex.
Examinations & Tutoring
Dr. Suter no longer provides vision therapy and testing for children. However, in their desire to still address the needs of families and kids in our community, her therapists are continuing their work offering private tutoring. They are expertly trained and experienced in techniques to improve visual performance and accuracy. Their skills are proven effective in improving reading, math, and laying a foundation for overall academic achievement. With the use of methods and programs such as Lindamood Bell and training from leaders in memory and visual processing, they are ready to to assist you in helping your child experience academic success.
