Can my loved one see?

Every part of the brain is involved in how we process and understand visual information. It is very common for patients to have vision changes after brain injury. These vision changes can include, but are not limited to:

  • Double vision
  • Blurred vision
  • Difficulties moving one or both eyes in all directions
  • Double vision looking at items close to face
  • Difficulties with smooth, coordinated eye movements

Throughout your loved one’s recovery and rehabilitation, their vision will be assessed for possible vision changes that can impact recovery and function. Eye doctors, such as a neuro-optometrist, can prescribe exercises to help the brain’s visual system improve after injury.
