Convergence Excess: Symptoms, Causes, Diagnosis and Treatment in PRIMARYCITY

According to the American Optometric Association, convergence insufficiency and convergence excess together are estimated to affect up to 20% of the population. Convergence excess is a condition in which the eyes over-converge, or turn inward, when trying to focus on nearby objects. This can cause symptoms such as eye strain, headaches, and double vision. These symptoms are commonly experienced after or during extended periods of close work, such as reading or using a computer. Treatment options for convergence excess may include vision therapy, corrective lenses, andor lifestyle changes. Early detection and treatment are important for maintaining healthy vision and preventing potential complications.

Take our online visual skills assessment to help identify if you or your child has a potential visual deficit that may be interfering with success in the classroom, work, or sports.

Treating convergence excess can improve your vision and reduce symptoms, making it easier to perform daily tasks and improving your overall quality of life.

Early detection of underlying conditions

In some cases, convergence excess can be a symptom of an underlying condition such as multiple sclerosis. We can perform a comprehensive eye exam to rule out any other underlying conditions and refer you to a specialist if necessary.

The Signs and Symptoms of Convergence Excess

Symptoms of convergence excess can vary from person to person, but some of the most common ones include:

Eye strain: This is perhaps the most common symptom of convergence excess, and it is characterized by a feeling of discomfort or tiredness in the eyes after reading or doing close work for an extended period.
Headaches: Many people with convergence excess experience headaches, particularly after reading or doing close work for a prolonged period.
Double vision: Some people with convergence excess may experience double vision, which can be particularly noticeable when reading or looking at a computer screen.
Blurred vision: Another symptom of convergence excess is blurred vision, which can be particularly noticeable when looking at objects up close.
Difficulty concentrating: People with convergence excess may also experience difficulty concentrating, particularly when trying to read or do close work.
Light sensitivity: In some cases, people with convergence excess may be more sensitive to light than usual, particularly when doing close work.
Dizziness: A few people with convergence excess may experience dizziness or vertigo, particularly when reading or doing close work for an extended period.
Eye fatigue: Eye fatigue is a common symptom of convergence excess, and it can be particularly noticeable after a long day of reading or doing close work.

If you are experiencing any of these symptoms, please call us at 111-222-3333 to schedule an evaluation. The earlier convergence excess is diagnosed, the easier it is to manage.

The Signs and Symptoms of Convergence Excess

Exploring the Possible Causes of Convergence Excess: Insights from Our Experienced Optometrist

There are various causes of convergence excess, including:

Genetics: Convergence excess can be hereditary and may run in families.
Eye muscle weakness: Weakness in the muscles responsible for controlling eye movements can cause the eyes to turn too much inward.
Accommodative dysfunction: Accommodation is the process by which the eyes focus on objects at varying distances. When the eyes struggle to adjust to changes in focus, it can lead to convergence excess.
Neurological conditions: Certain neurological conditions, such as multiple sclerosis, can affect the nerves that control eye movements and lead to convergence excess.
Trauma: In some cases, head trauma or injury to the eyes can cause convergence excess.
Eye strain: Prolonged periods of reading or doing close work can strain the eyes and may cause convergence excess.
Poor vision habits: Poor vision habits, such as holding reading material too close to the face or working in poorly lit environments, may contribute to convergence excess.
Eye fatigue: Eye fatigue may also contribute to convergence excess. When the eyes are tired, they may struggle to maintain proper alignment, leading to the eyes turning too much inward.

Understanding the Diagnosis of Convergence Excess and How We Can Help

Accurately diagnosing convergence excess is essential in developing an effective treatment plan. Here's what to expect during the diagnosis process:

Comprehensive eye exam

During a comprehensive eye exam, we will perform a range of tests to evaluate the health of your eyes and determine the presence of any underlying conditions that may be contributing to your symptoms.

Vision testing

Vision testing will evaluate the clarity of your vision and your ability to focus on objects at varying distances.

Eye alignment testing

Eye alignment testing will determine if your eyes are properly aligned when focusing on objects at varying distances.

Binocular vision testing

Binocular vision testing will evaluate how well your eyes work together as a team and assess the presence of any eye muscle imbalances.

Refraction

Refraction is a test that determines the precise prescription needed to correct any refractive errors you may have, such as nearsightedness, farsightedness, or astigmatism.

Cycloplegic refraction

Cycloplegic refraction involves using eye drops to temporarily paralyze the muscles that control the lens of the eye. This test can help determine the full extent of any refractive errors and rule out any underlying conditions.

Stereopsis testing

Stereopsis testing evaluates your ability to perceive depth and 3D images.

Cover testing

Cover testing evaluates the alignment of your eyes when focusing on objects at varying distances.

Near point of convergence testing

Near point of convergence testing assesses how closely your eyes can focus on a nearby object before they start to turn inward.

By performing a comprehensive eye exam and a range of specialized tests, we can accurately diagnose convergence excess and develop a personalized treatment plan to address your symptoms.

Effective Treatment Options for Convergence Excess

Convergence excess can be a challenging condition to manage. Fortunately, there are a range of treatment options available that can help alleviate symptoms and improve visual function. The Convergence Insufficiency Treatment Trial (CITT) showed that in-office vision therapy was the most effective treatment. In some cases our optometrist may discuss other treatment options, here are some of the treatment options that we may recommend:

Vision therapy

Vision therapy is a customized program of exercises and activities designed to improve the function of the visual system, including eye teaming and focusing skills. Vision therapy may be prescribed to help reduce symptoms of convergence excess.

Prism lenses

Prism lenses are designed to alter the way light enters the eyes, which can help alleviate symptoms of convergence excess. Prism lenses can be prescribed for eyeglasses or contact lenses.

Reading glasses

Reading glasses may be prescribed to help alleviate symptoms of convergence excess when reading or doing close work.

Pencil pushups

Pencil pushups are a type of vision therapy exercise that involves focusing on a small object, such as a pencil tip, held at arm's length and then gradually moving the object closer to the face. This exercise can help improve eye teaming and focusing skills, however is not as effective as in-office vision therapy according to the The Convergence Insufficiency Treatment Trial (CITT). Learn more about The Convergence Insufficiency Treatment Trial (CITT) here.

Computer glasses

Computer glasses may be prescribed to help alleviate symptoms of convergence excess when using a computer or other digital devices.

Lifestyle modifications

Making lifestyle modifications, such as taking breaks when reading or doing close work, can also help reduce symptoms of convergence excess.

Surgery

In rare cases, surgery may be recommended to correct a muscle imbalance that is contributing to convergence excess. This option is typically reserved for cases in which other treatment options have been unsuccessful.

It is important to note that the most effective treatment plan for convergence excess will vary depending on the individual patient's needs and symptoms. We will work with you to develop a customized treatment plan that is designed to alleviate your symptoms and improve your visual function.

How can I find an eye doctor near me?

If you don’t already have a trusted optometrist or you live too far from our optometry clinic in CITY, you could start your online search by typing in phrases such as "eye doctor near me," "optometrist near me," or "eye specialist near me."

Common Questions

What is convergence excess and insufficiency?

Convergence excess and convergence insufficiency are two conditions that affect the ability of the eyes to focus on nearby objects. Convergence excess occurs when the eyes turn too far inward when focusing on nearby objects, while convergence insufficiency occurs when the eyes have difficulty turning inward enough to focus on nearby objects.

How do you find excess convergence?

Excess convergence can be identified through a comprehensive eye exam, which may include tests of eye alignment, focusing ability, and visual acuity. One common test used to evaluate convergence excess is the near point of convergence test, which involves asking the patient to focus on a small object held at arm's length and slowly moving the object closer to the eyes until the patient reports seeing double or the eyes begin to drift outward.

What is esotropia and convergence excess?

Esotropia is a type of strabismus in which the eyes turn inward toward the nose. Convergence excess can contribute to the development of esotropia, as the excessive inward turning of the eyes can cause the eyes to become misaligned.

What is divergence excess?

Divergence excess is a condition in which the eyes turn too far outward when focusing on distant objects. This is the opposite of convergence excess, which involves excessive inward turning of the eyes when focusing on nearby objects.

Is convergence excess the same as divergence insufficiency?

No, convergence excess and divergence insufficiency are two separate conditions that affect the alignment of the eyes. Convergence excess involves excessive inward turning of the eyes when focusing on nearby objects, while divergence insufficiency involves difficulty turning the eyes outward to focus on distant objects.

What does convergence mean with eyes?

Convergence refers to the ability of the eyes to turn inward toward the nose when focusing on nearby objects. This is an important function of the visual system, as it allows us to maintain clear and single vision when reading, writing, or doing other close work.

What is accommodative excess?

Accommodative excess is a condition in which the eyes have difficulty relaxing their focusing muscles when looking at distant objects. This can lead to symptoms such as eyestrain, headaches, and difficulty seeing clearly.

What is convergence excess esophoria?

Esophoria refers to a type of eye misalignment in which the eyes tend to turn inward toward the nose, particularly when focusing on nearby objects. Convergence excess can contribute to the development of esophoria, as the excessive inward turning of the eyes can cause the eyes to become misaligned.

What is the difference between convergence and accommodative insufficiency?

Convergence insufficiency is a condition in which the eyes have difficulty turning inward enough to focus on nearby objects, while accommodative insufficiency is a condition in which the eyes have difficulty focusing on nearby objects. While these two conditions are related and may occur together, they involve different aspects of the visual system.
