Why You Should Get Your Eyes Checked After A Concussion

A concussion is a type of traumatic brain injury caused by a blow, bump or shake to the head, affecting normal brain function. Post-concussion, you may potentially experience a range of visual disturbances, collectively known as post-concussion vision syndrome or post-trauma vision syndrome. Approximately 90% of people experience eye symptoms after a concussion, necessitating a comprehensive eye exam post-injury, among other examinations.

How a Concussion Affects the Eyes

Following a concussion, visual symptoms may manifest due to the damage sustained by the brain. The force of impact can alter the normal function of your eyes, causing the following symptoms:

• Double Vision (Diplopia). You may see two images of a single object. This can occur due to trauma to the orbital bones, damage to the eye muscles or injury to the optic nerve.
• Light Sensitivity (Photophobia). This common post-concussion is characterized by discomfort when exposed to an illuminated space, triggering other symptoms like nausea and headaches.
• Altered Eye Movements. It may become difficult to track or follow objects with your eyes. You may also lose the range of motion in your eyes. Sudden jerking movements can occur as well. Disorientation may lead to feelings of nausea and dizziness.

Diagnosis and Treatment

Diagnosing a concussion typically involves a thorough medical history, a physical exam and potentially a CT scan. Treatments are primarily supportive, encouraging activities likely to lessen symptoms and encourage rest for an initial 24-48 hours. Those with persistent visual symptoms might need vision rehabilitation involving exercises to improve eye alignment, focus and coordination and therapies for light sensitivity.

Recovery Tips

Particular interventions can aid in your recovery from a concussion:

• Rest as much as possible.
• Restrict screen time in the first 48 hours post-concussion, as screen usage could slow down recovery.
• Gradually increase your physical activity levels, as long as it doesn’t trigger symptoms.
• Wearing eyeglasses or sunglasses might help reduce light sensitivity.
• Limit activities that require prolonged periods of close work, such as reading and taking frequent breaks until symptoms subside.

The usual time it takes to recover from a concussion is 10 to 14 days for adults and four weeks for children. If symptoms persist beyond these timeframes, seek immediate medical attention.
