Saccade Exercises for Reading After Concussion

Overcoming Reading Difficulties After a Brain Injury

Struggling to read after a concussion is a highly common and frustrating symptom. Whether you are experiencing blurred vision, dizziness, or headaches when looking at a page, these visual disturbances often stem from a disruption in your eye’s ability to move accurately from word to word. Incorporating targeted saccade exercises into your recovery routine can help restore the rapid eye movements required for reading, visual scanning, and daily functioning.

What Are Saccade Exercises?

Saccade exercises are a form of neuro-optometric and vestibular rehabilitation designed to improve the speed, accuracy, and control of rapid eye movements. Saccades are the quick, simultaneous jumps your eyes make to shift focus from one object to another. Unlike smooth pursuits, where your eyes track a moving target, saccades require your brain to instantly calculate the distance to a new target and program the eye muscles to “jump” there accurately. In a clinical setting, eye saccade training is used to help patients regain visual stability and cognitive focus following a neurological event.

Can Saccade Exercises Help Reading After Concussion?

Yes, saccade exercises can directly improve reading ability after a concussion. Reading is a complex cognitive task that relies heavily on continuous, microscopic saccadic eye movements. When you read a sentence, your eyes do not glide smoothly across the page; they make several rapid jumps (saccades) and briefly pause (fixations) to process the words.

According to the CDC, visual problems and cognitive difficulties—such as struggling to concentrate or process information—are common concussion symptoms. If the neural pathways controlling these rapid eye movements are disrupted by a mild traumatic brain injury (mTBI), your eyes may overshoot or undershoot the targeted words. This forces your brain to work overtime to correct the errors, leading to eye strain, brain fog, and headaches. Rapid eye movement exercises specifically target and retrain these neural pathways, improving reading endurance and reducing visual fatigue.

How to Perform Basic Saccade Exercises

Before beginning any saccade exercises for concussion, it is essential to consult with a healthcare provider, such as a physical therapist or vestibular specialist, to ensure these exercises are appropriate for your specific presentation.

Here is a foundational horizontal saccade drill you can try at home:

Setup

• Seated Position: Sit upright in a chair with your feet flat on the floor in a well-lit room.
• Targets: Place two distinct targets (such as two different colored sticky notes or playing cards) on a blank wall in front of you.
• Spacing: Position the targets about 12 to 18 inches apart, exactly at your eye level.
• Distance: Sit approximately an arm’s length away from the wall.

Steps

1. Keep your head completely still throughout the exercise. You may rest your chin on your fists to prevent accidental head movement.
2. Look directly at the target on your left. Ensure it is in sharp focus.
3. As quickly and accurately as possible, shift your gaze to the target on the right.
4. Focus on the right target until the image is clear. Do not attempt to read the target; just look at it.
5. Jump your eyes back to the left target and refocus.
6. Repeat this back-and-forth motion for 30 to 60 seconds.

How Should Saccade Drills Be Progressed?

To ensure continuous neural adaptation, saccadic eye movement therapy must be progressively challenged as your visual tolerance improves. According to clinical guidelines for concussion recovery, gradually exposing the brain to visual and vestibular stimuli is key to safe rehabilitation.

Here is how healthcare professionals typically progress these drills:

1. Directional Changes: Once horizontal movements are symptom-free, progress to vertical saccades (targets placed one above the other), and eventually diagonal and random visual patterns.
2. Cognitive Loading: Combine eye saccade training with cognitive tasks. Instead of simply looking at a blank target, use letters or numbers. Call out the letter you are looking at with each eye jump to engage your brain’s processing centers.
3. Postural Changes: Move from a seated position to a standing position. This introduces a balance component, requiring your brain to manage postural stability while simultaneously performing rapid eye movement exercises.
4. Dynamic Environments: Progress to performing the exercises while walking or standing on an unstable surface (like a foam pad).
5. The VOR Cancellation Method: Try moving your head and eyes in the same direction at the same speed to target a stationary object, which challenges the vestibular-ocular reflex (VOR) and saccadic coordination.

Common Mistakes During Saccadic Eye Movement Therapy

To get the most out of your vision training, avoid these common pitfalls:

• Moving the Head: The primary goal is to isolate eye movement. If your neck moves, your vestibular system takes over the visual scanning, defeating the purpose of the eye exercise.
• Moving Too Fast to Focus: Speed should not come at the cost of accuracy. If your eyes consistently overshoot the target (missing the mark), slow down your jumps until you can land on the target precisely every time.
• Holding Your Breath: People often unconsciously hold their breath during intense concentration or when anticipating dizziness. Remember to breathe naturally to avoid triggering tension headaches.
• Pushing Through Severe Symptoms: A mild, temporary increase in symptoms is normal as the brain adapts. However, if you experience severe dizziness, nausea, or sharp eye pain, stop immediately.

Tips for a Safe and Effective Recovery

Navigating concussion recovery requires patience and careful symptom management. Keep these tips in mind:

• Track Your Symptoms Daily: Use a journal or a digital app to monitor symptoms like dizziness, headache, brain fog, eye strain, and nausea before and after your exercises.
• Respect Your Limits: Pacing is critical. Shorter, more frequent exercise sessions are often more effective than one long session that leaves you exhausted for the rest of the day.
• Know When to Seek Help: If your reading difficulties do not improve, or if you experience worsening vestibular symptoms, consult your healthcare team. You may require specialized evaluation for conditions like Binocular Vision Dysfunction (BVD) or an undiagnosed vestibular disorder like vestibular neuritis.

Key Takeaways

• Saccades are essential for reading: These rapid eye movements allow your eyes to jump accurately from word to word.
• Concussions disrupt visual accuracy: Damage to neural pathways can cause saccades to become jittery or inaccurate, resulting in reading fatigue and headaches.
• Exercise progression is necessary: Recovery requires moving from basic, seated horizontal eye jumps to cognitively and physically demanding tasks like standing balance and cognitive dual-tasking.
• Symptom tracking is vital: Mild symptom flares are normal, but exercises should be stopped if they cause severe nausea or pain.
