Specialty Evaluations

Infinite Vision provides specialty vision evaluations in addition to our normal eye exams. The evaluation covers many essential visual skills including the following:

Post-Injury Evaluation

The effects of a Traumatic Brain Injury can produce many vision issues. Patients often experience fatigue, inattention, headaches and double vision. Oftentimes, patients will notice they begin to lose their place or skip words when reading. Traumatic Brain Injury can also cause difficulty processing visual information and have trouble with concentration. The injury can also cause stress to both the central and peripheral vision systems. This stress can cause motion sickness, imbalance or difficulty tolerating crowded environments.

Due to the major impact on the visual system a Traumatic Brain Injury may cause, immediate assessment and treatment is recommended. This allows the needs of the patient to be addressed as they begin the process of rehabilitation.

This type of evaluation typically lasts one hour.

Binocular Evaluation

When performing this type of evaluation, Dr. Katie looks at all five areas of vision. They are:

  1. Visual Acuity (Does this patient have 20/20 vision? Does this patient need glasses? This is often rarely the case as only 5% of vision issues are caught when testing for 20/20 vision.)
  2. Tracking (How fast and accurately do the eyes move? This is the movement the eyes make while reading. Deficiencies in this area cause people to lose their place when they read, skip words or lines and have difficulty copying from the board.)
  3. Binocular Skills (How well do the eyes converge and diverge? How strong are the eyes and how coordinated are they? Decreased binocular skills cause fatigue and strain with near work. Patients may have poor attention with near work. They may even notice double vision or words moving on the page when they read.)
  4. Focusing Ability (Also referred to as “Accommodation”. How strong are the muscles that focus the eye and how fast are they? Focusing  issues can cause fatigue, headaches, blur and/or avoidance of near work.)
  5. Visual Perception (Also referred to as “Visual Processing”. Using standardized testing, we evaluate how accurately patients perceive visual information once it has entered the brain. Issues with visual perception can cause patients to have difficulty recognizing words consistently and can contribute to some types of of letter reversals. Visual perception disorder is not the same issue as dyslexia but both conditions may have similar symptoms. Our testing can reveal how much a role vision may be playing.)

The Binocular Vision Evaluation is performed in two phases. The initial standardized testing of tracking and visual perception is done at our vision therapy office and typically lasts about an hour. The testing is done one-on-one and no other patients are present in the office at that time. Once the testing is complete, the patient transitions to the primary care office. This is where the rest of the binocular skills are assessed along with ocular health. This part of the exam lasts 30-45 minutes. Upon completion of all testing, results are reviewed at the conclusion of the eye examination. Dr.Katie will review any diagnoses and treatment options. This part of the evaluation last 20-30 minutes. Overall the evaluation typically last about 2 hours. A written report of the entire evaluation will be provided in the following weeks.

Prism Evaluation

Prism evaluations can be a solution to alleviating double vision. A prism is a type of lens added to glasses that allows the doctor to shift and align the images between the two eyes to alleviate eyestrain and double vision. In addition, prism evaluations can be an effective way to help patients suffering from visual field loss. Using yoked prism, the doctor can shift a patient’s visual field to allow for greater peripheral vision.

This type of evaluation typically last about one hour and is appropriate for patients who have unresolved double vision.
