Can Hitting Your Head Cause Blurred Vision?

Have You Experienced Blurry Vision After Hitting Your Head 640×350People often experience blurry vision after brain trauma, especially from a concussion, a type of traumatic brain injury (TBI). In fact, about 90% of patients with a traumatic brain injury will experience some visual symptoms that can negatively affect their quality of life.

Fortunately, neuro-optometric therapy can offer relief to many patients with head injuries. Contact Vision Advancement Center in Frisco to find out how we can help restore your vision and quality of life.

How Can Hitting Your Head Affect Your Vision?

While some minor head injuries result in nothing more than a bump or bruise, in more serious head injuries, known as traumatic brain injuries (TBIs), the brain impacts against the hard skull, often with powerful force. This impact can damage fragile nerves and blood vessels in the brain. Since 70% of our brain is responsible for visual processing, it’s no surprise that a TBI can cause blurred vision and other uncomfortable post-injury visual symptoms, such as:

  • Headaches
  • Eyestrain
  • Sensitivity to light
  • Dizziness
  • Poor hand-eye coordination
  • Double vision
  • Confusion
  • Memory problems

Why You Should Schedule an Appointment with a Neuro-Optometrist

When a head injury occurs, vision problems often take a backseat to more urgent concerns, such as relieving pressure on the brain or treating lacerations to the head or face. But that doesn’t mean vision problems can or should be ignored. Any vision problems related to a head injury can severely affect a person’s ability to work, study, drive and carry out day-to-day tasks.

A neuro-optometrist diagnoses and treats a whole range of communication problems between the visual system and the brain caused by traumatic brain injuries (TBI), physical disabilities or other neurological conditions, such as a stroke, Parkinson’s disease or multiple sclerosis.

Can Vision Be Restored After a Head Injury?

Yes, especially with the help of neuro-optometric rehabilitation. The first step is scheduling a functional eye exam with your neuro-optometrist. During the exam your eye doctor will test the following visual skills:

  • Eye teaming
  • Eye tracking
  • Eye focusing
  • Visual processing
  • Peripheral vision
  • Spatial awareness
  • Lazy eye and eye turns

What Is Neuro-Optometric Rehabilitation?

Once your neuro-optometrist has diagnosed your condition, they will prescribe a customized program to relieve your symptoms. Neuro-optometric rehabilitation is a scientifically proven treatment plan that helps strengthen the functioning of the neurologically damaged visual system. The program relies on the brain’s neuroplasticity to improve the communication between the brain and the eyes.

Neuro-optometric rehabilitation therapy involves in-session training and at-home exercises that will help restore normal vision. These may include:

  • Customized program of eye exercises
  • Prism glasses that help the brain and eyes to work together
  • Computer-assisted eye exercises
  • Corrective eye patches

Frequently Asked Questions with Dr. Lindsay Berry

Q: How Long Does Blurred Vision Last After a Head Injury?

  • A: Although blurry vision sometimes goes away a couple of weeks after a head injury, it’s best not to leave it to chance, hoping visual problems will correct on their own. If you experience any vision problems after a head injury, it’s recommended to schedule an appointment with a neuro-optometrist. Neuro-optometric therapy can often correct blurry vision long-term by dealing with the root cause of your vision problems following a TBI.

Q: Is a Traumatic Brain Injury the Same as a Concussion?

  • A: A TBI is a damage to the brain caused by impact. A concussion is considered a milder type of TBI. However, even a mild concussion can cause significant vision problems.

Can Your Vision Change After a Concussion?

women rubbing her head from neuro vision problemsIf you’ve hit your head in a fall while playing sports or in any other type of accident, your vision may have been impacted.

Between 69% and 82% of people who’ve experienced concussions report visual problems, such as eyestrain and double or blurred vision.

Head trauma causes the brain to move within the skull. The movement can stretch the fragile cranial nerves and can even damage brain cells. Since vision relies on efficient communication between the eyes and the brain, a concussion can disrupt these neural pathways, affecting your vision.

The resulting condition is called post-trauma vision syndrome (PTVS).

How Does a Concussion Affect Vision?

Our vision depends on our brain’s ability to accurately receive and interpret the images sent by our eyes. Therefore, anything that impacts the brain can severely affect our ability to see clearly. When we suffer head injuries caused by a traffic accident or a serious fall, the resulting head injury can impact the communication between our eyes and brain.

Although your eyes may be healthy, your vision may be blurred, or you might start seeing double or experience eye strain due to post-trauma vision syndrome.

What Is Post Trauma Vision Syndrome?

Post-trauma vision syndrome refers to a number of visual problems that tend to occur following a severe head injury. If you have PTVS, you may have trouble with:

  • Focusing – changing focus from close to far or keeping your vision clear
  • Eye teaming or binocular vision – your eyes’ ability to coordinate
  • Depth perception – judging distance or the relationship of one object to another
  • Eye-tracking – visually following an object or text on a screen or page
  • Peripheral vision – seeing things from the side of the eyes
  • Eye alignment – the eyes aren’t aligned correctly or point in different directions

Any one of these visual problems can negatively affect your ability to perform day-to-day tasks and significantly lower your quality of life. Driving, reading, watching TV, participating in sports, enjoying hobbies and even socializing can become difficult.

Why You Need a Neuro-Optometrist

A neuro-optometrist is trained to diagnose and treat visual problems related to the nervous system caused by head injuries, strokes and neurological diseases. After assessing your visual system for any aberrations, your neuro-optometrist will prescribe a customized treatment plan to strengthen your visual system and improve your quality of life.

What Treatments Improve Vision Following a Concussion?

A neuro-optometrist may prescribe any of the following to relieve symptoms after a concussion and help you see and feel better:

  • Prescription lenses – especially for blurry vision
  • Prism lenses
  • Syntonic phototherapy – the use of light to create balance in the autonomous nervous system and restore vision
  • Neuro-optometric therapy – a customized eye exercise program designed to rehabilitate your visual skills

How Long Do Visual Problems Last After a Concussion?

Typically, visual problems caused by a concussion don’t become noticeable for some time. Symptoms of visual problems can appear or remain for weeks, months or even years after the original incident. Any person who has had a concussion should be assessed by a neuro-optometrist, even if they’re not experiencing any obvious visual problems.

If you’re still experiencing any visual symptoms of post-traumatic vision syndrome, even weeks or months after your head injury, it’s essential to see a neuro-optometrist for diagnosis and treatment. If this is your case, we invite you to schedule your appointment with Dr. Lindsay Berry at today.

Frequently Asked Questions with Dr. Lindsay Berry

Q: Can a concussion permanently change your vision?

  • A: In some cases, a concussion can permanently impact your vision, especially if your visual system or optic nerve has been damaged. The good news is that most visual problems caused by a head injury respond well to neuro-optometric rehabilitation therapy.

Q: Why can it take time for concussion-related vision problems to be diagnosed?

  • A: Diagnosis can depend on several factors. If someone has been in a serious accident, their physicians are focused on life-threatening injuries. As a result, all but the most obvious visual symptoms, such as vision loss, may be missed. In other cases, the signs of PTVS can be very subtle and undetectable in a routine eye exam. That’s why anyone who has experienced a concussion should have their vision thoroughly examined by a neuro-optometrist.

    Do You See Better When You Tilt or Turn Your Head?

    blue eye tilted head to see betterDo you find that you need to tilt or turn your head to see better? This is known as an anomalous and compensatory gesture. Many people – including children – don’t even realize they’re doing this until their neck begins to feel really sore. Naturally, it’s hard to imagine that the source of their problem is their eyes or the optic nerves.

    Why Does My Vision Improve When I Tilt or Turn My Head?

    You may turn or tilt your head for any of the following reasons:

    Eye Misalignment (Strabismus)

    When your two eyes are misaligned or “crossed” (strabismus), they aren’t able to point in the same direction. The result: each eye sends a different image to your brain, which then struggles to merge the images to create one clear, unified 3D image. Moving your head compensates for this and may enable your brain to more comfortably combine the images to see more clearly.

    This misalignment can be caused by a malfunction of the nerve that controls the muscles surrounding the eyes. Depending on which nerves and muscles are affected, the head turn or tilt is essentially an adjustment to enhance the comfort and clarity of vision.

    Duane Syndrome

    Duane syndrome is a specific type of strabismus. It is a congenital disorder of the 6th cranial nerve that controls the lateral rectus muscle. As a result, the eyes may rotate inward and outward and can lead to compensatory head movements.

    Nystagmus

    Nystagmus, involuntary jerky or shaky eye movements, can cause you to tilt your head in a specific position when the nystagmus is slow or stops. This is called a “null point.” Nystagmus can have a neurological basis, as in cases of:

    • Stroke
    • Trauma to the head
    • Brain tumor
    • Central nervous system diseases, such as multiple sclerosis

    Ptosis

    Ptosis is often called “droopy eyelid,” and can be caused by an injury to the muscles surrounding the eyelid or to the nerves controlling these muscles. People with ptosis will compensate by looking upward to see objects as if trying to see past the eyelid.

    Refractive Errors

    Refractive errors occur when the eye is either too long or the corneal focusing power is too high or too low. They aren’t a result of a neurological problem. However, refractive errors often cause a child or adult to tilt or move their head to compensate for their blurry vision.

    These are the refractive errors that affect eyesight:

    • Astigmatism
    • Myopia (nearsightedness)
    • Hyperopia (farsightedness)
    • Presbyopia (age-related farsightedness)

    In the event of a refractive error, you or your child may also squint your eyes in an attempt to see better. Having an eye exam can determine the type of refractive error and the best way to correct the problem.

    How Can I Stop By Head From Tilting or Turning to See Better?

    If you find that you’re tilting or turning your head to see objects or read better, it’s important to schedule an eye exam to identify the cause of the problem.

    Patients with ocular neurological problems may be experiencing some of these symptoms:

    • Eye strain, headaches or migraines
    • Eye turn or blurry vision
    • Reading or attention problems
    • Difficulty moving the eyes
    • Involuntary eye movements
    • Pressure in the eyes or head
    • Uneven pupils
    • Double vision
    • Droopy eyelids
    • Facial distortion

    If your eye doctor suspects that your eye condition may be rooted in the nerves or the brain, they may recommend an appointment with a neuro-ophthalmologist, who is trained to diagnose and treat eye irregularities with a neurological cause.

    Frequently Asked Questions with Dr. Lindsay Berry

    Q: What are some causes of neurological problems that affect the eyes?

    • A: – Inflammation of the optic nerve (optic neuritis)
      – Swelling of the optic nerve (papilledema) – commonly caused by increased pressure inside the brain
      – Nerve damage leading to paralysis of eye muscles – this leads to strabismus or misaligned eyes
      – Optic neuropathy – can be caused by toxic substances such as alcohol, tobacco or B12 deficiency
      – Stroke or brain tumor

    Q: How is strabismus treated?

    • A: Strabismus, characterized by crossed or misaligned eyes, is treated by:- Eyeglasses for milder cases
      – An eye patch placed over the stronger eye to help the weaker eye become stronger
      – Orthoptics – eye exercises
      – Botox – can temporarily weaken the overactive muscle
      – Surgery on the eye muscles

    Double Vision After Brain Surgery

    Double Vision After Brain SurgeryDouble vision (diplopia) can occur after a traumatic brain injury, a stroke or certain types of surgery due to a disruption in the connection between the nerves and extraocular muscles that control the eyes’ position and movements.

    Diplopia following brain surgery is usually temporary and can take a few days or weeks to resolve, depending on the source of the problem. In the meantime, people who suffer from double vision after an operation can benefit from specific glasses and neuro-optometric rehabilitation through eye exercises that help restore single vision.

    If you are experiencing diplopia after brain surgery and want to know which treatment is right for you, make an appointment with Dr. Lindsay Berry at Vision Advancement Center today.

    What Causes Double Vision After Brain Surgery?

    The brain is connected to the eyes through a network of nerves — including the optic nerve — that controls the movement and alignment of the eyes. These nerves can be impacted by brain disorders, tumors and strokes, or during brain cranial surgery. Brain surgeries can disrupt the connection between the brain and the eyes, resulting in the misalignment of the eyes and double vision.

    Alternatively, the muscles surrounding the eyes that keep the eyes aligned and focused can be damaged during surgery, affecting their ability to perform accurately and effectively.

    Ordinarily, having two eyes means the brain receives two images, which it converts into one single 3D image of the world. However, an injury to the eye muscles can cause an eye misalignment, making it impossible for the brain to fuse the two images into one single, clear image — resulting in double vision.

    What Are Other Symptoms of Damage to the Visual System?

    Although the most obvious sign of damage to the visual system after brain surgery is double vision, patients may experience any of the symptoms below:

    • Eyestrain
    • Crossed eyes
    • Headaches
    • Pain when moving the eye
    • Droopy eyelids
    • Nausea
    • Eye weakness

    How to Treat Diplopia After Brain Surgery

    There are several treatments for diplopia after brain surgery.

    Prism glasses

    After an eye exam your eye doctor may prescribe prism glasses that work by altering the path of light rays and compensate for any misalignment of the two eyes. These lenses allow the brain to fuse the two images from the eyes to create a clear and single 3D view of the world around us.

    Eye Patches

    Your eye doctor may recommend wearing an eye patch because it removes the second image from a weaker eye reaching the brain. Using a patch can temporarily remove the visual disturbance and prevent you from seeing double images, but is often not the best long-term solution. It is important to follow a precise regimen for eye patch wearing and not deviate from the instructions without first consulting your doctor.

    Neuro-Optometric Rehabilitation

    One effective way to regain clear and comfortable vision after brain surgery is through neuro-optometric rehabilitation, which is a personalized eye exercise program that will strengthen the connection between the brain and your eye muscles, with the goal of improving your quality of life by regaining your clear 3D vision.

    Following a functional vision evaluation to assess visual problems, your optometrist may prescribe customized exercises to re-establish the effective communication between your eyes and brain.

    How Long Will It Take to Recover from Diplopia?

    Usually, diplopia that develops following surgery is temporary, and with treatment, regular vision can be restored in days or weeks. In cases that persist, eye patching, prism glasses and neuro-optometric rehabilitation usually resolve diplopia within weeks or months. In rare cases, eye surgery may be required to correct diplopia.

    If you are experiencing double vision after brain surgery, schedule an appointment with Vision Advancement Center today.

    Frequently Asked Questions with Dr. Lindsay Berry

    Q: What are the different types of diplopia?

    A: All types of diplopia involve seeing two images, but there are different forms of diplopia, depending on the positioning.

    • – Horizontal diplopia – images are separated laterally
    • – Vertical diplopia – one image is higher than the other
    • – Monocular diplopia – diplopia continues in one eye when the other is closed.

    Monocular diplopia can be caused by conditions such as astigmatism, cataracts or keratoconus. Diplopia can be temporary, intermittent or constant.

    Q: What are the common causes of diplopia?

    A: Diplopia can be caused by the following: Brain trauma or brain tumor

    • – Stroke
    • – Eye problems like keratoconus, dry eye and cataracts
    • – Brain surgery
    • – Cranial nerve palsy
    • – Eyestrain

    Concussions & Vision Problems After a Car Accident

    Car Accidents 640×350While a car accident can impact our lives in an instant, its effects on our eyes and vision may not be detected until later.

    That’s why it’s important to be aware of the ways a concussion — a type of traumatic brain injury (TBI) — caused by a car collision can affect the eyes, and to make an appointment with Dr. Lindsay Berry at Vision Advancement Center following even a minor car accident.

    If a problem is found, you may benefit from vision therapy, a program designed specifically to rebuild the visual system and help recover visual skills.

    How Often Do Concussions and Vision Problems Occur After Collisions?

    Everyone knows that concussions cause headaches, but many people aren’t aware of the negative effects a TBI can have on a person’s vision.

    Concussions are considered minor TBIs, but this doesn’t mean that the problems associated with concussions are minor. According to the Centers for Disease Control and Prevention, up to 75% of TBIs are concussions.

    Furthermore, 90% of people who suffer concussions after external impacts such as a car accident experience vision problems. Vehicular accidents, serious falls and sports injuries are some of the leading causes of TBIs, including concussions.

    The Connection Between Concussions, TBIs and Vision Problems

    A concussion or other TBI may disrupt the communication between the eyes and the brain. The sufferer may experience some or all of the following:

    • Double vision
    • Headaches
    • Eye fatigue involving visual activities, such as reading
    • Blurred vision
    • Loss of visual field
    • Problems with eye convergence: the inability to point both eyes to the same place at the same time
    • Eye tracking problems
    • Accommodative insufficiency – the inability to focus on near objects

    A TBI can also cause a range of eye emergencies that require urgent medical attention, including:

    • Retinal detachment
    • Optical nerve damage
    • Vitreous hemorrhage

    This is why it’s so important to have a comprehensive functional eye exam following a car accident to detect any potential eye damage, diagnose vision problems and recommend a course of treatment.

    Treating Vision Problems Associated with Concussions or TBIs

    To diagnose and treat vision problems following a car accident, it is important to seek out a neuro-optometrist, an eye doctor or who is specially trained to treat eye problems associated with the nervous system.

    The neuro-optometrist will examine the patient’s eyes and visual system following a car accident or other type of traumatic brain injury. This eye exam is beyond the standard 20/20 sight test, as it also assesses the accuracy of eye movements and many other visual skills.

    If the vision problem is connected to neurological damage or brain injury, the neuro-optometrist will determine the specific visual issues and prescribe an appropriate form of treatment to address the underlying problem.

    The eye doctor may prescribe specific glasses, including prism lenses or a program of neuro-optometric rehabilitation, a customized program of in-office and at-home exercises to strengthen the visual system and aid in the patient’s recovery.

    If you have been involved in a car accident or may have experienced any type of traumatic brain injury, contact Dr. Lindsay Berry at Vision Advancement Center today for an eye exam and a treatment program.

    Frequently Asked Questions with Dr. Lindsay Berry

    Q: What are the symptoms of retinal detachment?

    A: Retinal detachment occurs when the retina becomes separated from its supportive tissue at the back of the eye. Some of the initial signs of a detached retina are:

    • – Seeing spots, floaters and light flashes
    • – Poor and blurry vision
    • – Perceiving a shadowy portion from the top or side of the eye
    • – Reduced peripheral visionIt is estimated that one in seven people who see spots, floaters or flashes of light have a retinal tear or detachment.

    It is important to see an eye doctor if you have symptoms because if this condition is left untreated, it can lead to vision loss.

    Q: What are some treatments for retinal detachment?

    A: To correct retinal detachment, surgery is required to move the retina back into place. The three main types of surgeries are:

    • – Scleral buckling surgery–attaching a small band on the outside of the sclera of the eye to push the retina back into position
    • – Vitrectomy–the fluid or vitreous humor is extracted from the eye and replaced with a silicone gel
    • – Pneumatic retinoplexy–the surgeon injects a gas bubble into the vitreous humor to push the retina into position.

    An eye doctor will perform an eye exam to determine which kind of surgery is needed to treat retinal detachment in the case of each patient.
