The Eyes Have It: Vision Dysfunction in Adults with Acquired Brain Injury


Many have said the eyes are the window to the soul. Of all the five senses, the eyes play an extremely important part in how humans receive information from the world. It is estimated that 80% of information we take in is through our visual system. Vision impacts performance in almost everything we do on a daily basis, and changes in vision can negatively impact our ability to complete these activities safely and independently. Health care providers strive to help their clients achieve their highest level of independence. An understanding of the visual system and changes associated with acquired brain injury (i.e. stroke and traumatic brain injury) can help health care providers facilitate their client’s safety and independence.

Course Goal: In this course, the participant will gain an understanding of how the human visual system works and how that system can be impacted by stroke or traumatic brain injury. You will be able to identify vision changes in your clients and develop a treatment strategy.

Learning Objectives:

  • Identify the major structures of the human eye
  • List the major cranial nerves and extraocular muscles associated with vision
  • Describe the common visual symptoms that might be found in a person who suffered a stroke or traumatic brain injury
  • Demonstrate the ability to perform a basic vision screening for an adult
  • Develop appropriate vision exercises to be carried out as part of a rehabilitation program

Course Description: This introductory course on the human visual system is designed for therapists and health care providers working with adults who have suffered vision changes as the result of a neurological incident, such as traumatic brain injury or stroke. The learner will be provided with valuable information on the human brain, the anatomy of the human eye and how vision can be affected by a brain injury or stroke. In addition, the learner will be able to identify changes in their client’s visual systems and complete a basic vision screening to further define the deficit areas. Finally, the course will provide the participant with basic vision exercises that can be incorporated into a rehabilitation program.

Teaching methods for this course include:
instructor lecture via web-based text, email to instructor and fellow students, pictures and graphics, live web links, references and resources, activities/assignments to complete on your own, glossary and resources for recommended text books/materials.
