3 Ways Neuro-Optometry Can Help Stroke Survivors

3 Ways Neuro Optometry Can Help Stroke Survivors 640Approximately 15 million people around the globe suffer from a stroke each year. An alarming two-thirds of stroke survivors experience some degree of visual dysfunction after the incident.

These problems can range from irritating to debilitating and can seriously affect a person’s quality of life and ability to function.

Thankfully, there is hope for stroke survivors who suffer from stroke-related vision problems.

At Lifetime Eyecare, we are dedicated to helping post-stroke patients heal their visual system for long-lasting relief and a better quality of life.

Below, we’ll explore how a stroke can impact vision and what a neuro-optometrist can do to help.

What is a Stroke?

A stroke occurs when insufficient oxygen is delivered to the brain tissue, either due to leaking or bursting blood vessels, or a blockage within the blood vessel.

Serious brain damage can occur within minutes of a stroke, making early intervention crucial.

Signs of a stroke include:

  • Paralysis
  • Numb or weak limbs
  • Slurred speech
  • Confusion
  • Trouble walking
  • Dizziness or loss of coordination

Because a large portion of the brain is involved with vision, a stroke can also affect the eyes and visual processing.

How a Stroke Can Affect Vision

If a stroke occurs in the areas of the brain that control the eye, it can cause:

  • Blurred vision
  • Visual field loss
  • Double vision
  • Dry eye syndrome
  • Sensitivity to light
  • Nystagmus — rapid, uncontrolled eye movements

When a stroke affects the areas of the brain responsible for visual processing, it can cause:

  • Visual neglect — when the patient ignores stimuli from a portion of their visual field
  • Visual hallucinations
  • Poor depth and movement perception
  • Difficulty recognizing objects or people

3 Ways a Neuro-Optometrist Can Help Stroke Survivors

1. Identify and Diagnose Any Visual Dysfunction

A neuro-optometrist has the training and experience required to thoroughly identify, diagnose and treat even slight visual dysfunction that may be causing symptoms.

Your neuro-optometrist will perform a functional visual evaluation to assess neurological vision-related complications and identify the type of vision loss caused by the stroke.

 

2. Rehabilitate the Visual System

Neuro-optometric rehabilitation therapy includes visual exercises that retrain the brain and eyes to work together.

During a stroke, certain neural connections may become damaged. Neuro-optometric rehabilitation aims to restore those connections and heal the visual system for long-lasting results.

3. Prescribe the Correct Lenses or Prisms, As Needed

A neuro-optometrist can prescribe specialized lenses or prisms that aid in the therapeutic process. Prism lenses shift images into the functioning part of a patient’s visual field, or, in the case of double vision or visual neglect, unite the images the two eyes are sending to the brain. In some cases, prisms can instantly relieve symptoms like disorientation or double vision.

Some patients only visit an occupational therapist or physical therapist after a stroke—and while these therapies are often necessary and helpful, they cannot treat the visual system or prescribe prisms.

How We Can Help

Stroke survivors deserve the best in rehabilitative care. That’s why we are passionate about restoring their independence and offering relief from incapacitating visual symptoms.

Furthermore, neuro-optometric rehabilitation therapy offers the added benefit of diminishing vertigo and depression and increasing confidence levels.

If you or a loved one has suffered a stroke, we can help. To schedule your functional visual evaluation, contact Lifetime Eyecare today.

Lifetime Eyecare serves patients from Edmonton, Leduc, Sherwood Park, and Beaumont, all throughout Alberta.

 

Frequently Asked Questions with Dr. Mohammed Jomha

Q: #1: Other than stroke patients, who can benefit from neuro-optometric rehabilitation therapy?

  • A: Neuro-optometric rehabilitation therapy can help any person suffering from visual dysfunction after a head injury, traumatic brain injury or stroke, or anyone with neurological conditions that impact their vision. If you experience any symptoms associated with visual dysfunction like dizziness, disorientation, headaches, nausea or difficulty concentrating— it may be time to visit your neuro-optometrist.

Q: #2: Can neuro-optometry help if the stroke occurred months or years ago?

  • A: The best time to start treatment is as soon as possible following a stroke or head injury, but treatment can also be effective years later. The basis of neuro-optometry is neuroplasticity—the brain’s ability to change and build new neural connections. As long as a person is alive, there is potential to heal their visual system.

4 Ways Vision May Be Affected Following A Stroke

headache womanAbout 2 in 3 stroke survivors live with some degree of visual dysfunction following the stroke. Although all brains are different and everybody reacts differently, 4 major categories of vision loss can be caused by a stroke.

A stroke can damage any segment of the neural pathway that connects the eyes to the brain or a section of the brain that processes the images the eyes send it. Damage to either area can lead to vision loss.

Stroke-related vision problems can make daily living a challenge, but there is hope for stroke survivors who suffer from visual symptoms.

In honor of World Stroke Awareness Month, we’ll explore 4 types of stroke-related visual problems, and how Lifetime Eyecare can help.

1. Visual Field Loss

A stroke can damage certain areas of the brain responsible for either central or peripheral vision, causing a portion of the visual field to be lost, causing vision to be ‘blacked-out’ or have ‘blind spots.’

In most cases, the same area of the visual field is lost in both eyes. This condition is called homonymous visual field loss, meaning a person may not be able to see the right or left side of their visual field from each eye.

Affected individuals may have difficulty with reading and may bump into things located in their blind spots.

2. Visual Processing Difficulties

Sometimes, a person may be able to see everything in their visual field but will have problems processing that visual information. For example, they may have the ability to see another person’s face, but might not recognize it. They may also have difficulty identifying or interacting with common objects, affecting daily tasks such as making a cup of coffee.

Visual neglect is the most common type of visual processing problem. People with this condition aren’t aware that they aren’t seeing people or objects on the right or left side of their visual field.

3. Eye Movement Problems

A stroke can damage the delicate nerves that control the eyes’ movements. A person who cannot control their eye nerves may have difficulty moving their eyes in order to shift their focus from one object to the next or have trouble tracking moving objects.

Nystagmus (involuntary and rapid eye movements) is also a possible complication of ocular nerve damage.

If only one eye is affected, the patient will usually experience double or blurred vision. Whether one or both eyes are affected, poor depth perception can result from eye movement dysfunction.

4. Dry Eye Syndrome

Stroke-related muscle weakness is common, especially in the eyes and face. If this occurs, the eyelids may not be able to fully close during blinking or while asleep. This can lead to dry eye syndrome, causing symptoms like red, itchy, watery, burning eyes and light sensitivity.

Fortunately, many of these post-stroke visual symptoms are treatable with neuro-optometric rehabilitation therapy.

A customized neuro-optometric rehabilitation therapy program can help you return to your normal routine, or at least make daily life less challenging.

If you or a loved one have suffered a stroke, speak with our optometrists about getting your vision evaluated to identify deficiencies in the visual system. If a problem is found, we’ll help guide you through all of your treatment options for the best possible outcome.
