Concussion & Vision

Important Disclaimer:
If your child experiences a severe concussion with symptoms such as loss of consciousness, confusion, repeated vomiting, seizures, or persistent worsening headaches, seek immediate medical attention and bring them to the nearest emergency room. These could be signs of a more serious condition that requires urgent care.

When a child suffers a concussion, it affects the brain in many ways – and one of the most common impacts is on vision.

What is a Concussion?

A concussion is a type of mild traumatic brain injury (TBI) caused by a blow or jolt to the head or body that causes the brain to move rapidly within the skull. This movement can lead to changes in the brain’s normal functioning, resulting in a range of physical, cognitive, and emotional symptoms.

Common Causes of Concussions

  • Sports injuries (e.g., football, soccer, or hockey)
  • Falls (especially in young children or older adults)

  • Car accidents
  • Physical altercations or accidents

How a Concussion Affects Your Child’s Vision

Concussions can have a significant impact on your child’s vision, leading to both temporary and long-term problems. After a concussion, the brain’s ability to process visual information can be disrupted, making it harder for your child to focus, read, or even navigate their environment. This is because the brain and eyes work together to interpret what we see, and a concussion can interfere with this coordination.

Common Vision Issues After a Concussion

  • Blurry Vision: Difficulty seeing clearly, which may come and go.
  • Double Vision (Diplopia): Seeing two images of a single object.

  • Sensitivity to Light (Photophobia): Discomfort or pain when exposed to bright lights.
  • Trouble Focusing or Concentrating: Difficulty maintaining focus on tasks like reading or schoolwork.
  • Eye Strain or Headaches: Particularly after prolonged reading or screen time.

  • Difficulty with Depth Perception: Challenges with judging distances, which can affect coordination and balance.

In some cases, a concussion may also disrupt the brain’s control over eye movements, causing misalignment (strabismus) or making it harder for the eyes to track objects properly. This can result in double vision or difficulty following moving objects.

How Concussion Affects the Brain?

A concussion affects the brain’s communication pathways, including those responsible for controlling eye movements and processing visual information. As a result, the brain may struggle to coordinate both eyes and process visual information accurately, leading to the symptoms mentioned above.

Common Signs and Symptoms of Concussion?

  • Blurred or double vision
  • Frequent headaches, especially when reading or focusing
  • Eye strain or discomfort after using a device or reading
  • Sensitivity to light
  • Difficulty concentrating or focusing on tasks
  • Balance problems or dizziness
  • Trouble with depth perception, affecting activities like sports or driving

If your child is showing any of these symptoms after a concussion, it’s essential to schedule an eye exam with an optometrist who specializes in post-concussion care. Early detection and treatment can help your child recover more quickly and prevent long-term vision issues.

What You Can Do?

Vision problems after a concussion can have a significant impact on your child’s daily activities. Difficulty with reading or concentrating can affect school performance, while balance issues or double vision can make physical activities, including sports, more challenging and unsafe. Since many children may not recognise the link between their concussion and vision problems, it’s important to keep an eye out for any changes in their visual behaviour.

  • Monitor for signs of blurry vision, double vision, eye discomfort, or headaches.
  • Encourage rest for both the eyes and the brain, and reduce screen time or activities that may strain their vision.
  • Schedule an eye exam with a professional who understands concussion-related vision problems.

  • Follow your eye care professional’s advice for exercises or therapy that may help restore proper vision.

  • Be patient. Recovery can take time, and it’s essential to give your child time to heal before returning to high-demand activities.
