10 Symptoms and Signs of Concussion

9. Visual Disturbances

Head trauma and concussions can affect the visual system. The group of symptoms causing blurred vision, eye coordination problems and dizziness is referred to as “post-trauma vision syndrome”.

The main signs include:

  • Dizziness;
  • Walk or gait issues;
  • Focusing problems;
  • Headaches;
  • Double vision.

People with with a history of vision issues are likely to experience more severe symptoms of post-trauma vision syndrome.

Whereas mild concussions may affect the vision slightly (difficulty focusing on near objects or digital devices), severe concussions can lead to double vision and even blindness. [7]
