As a parent, it’s natural to feel worried if you notice something unusual about your child’s eyes or vision. Perhaps you’ve observed their eyes cross inwards or deviate outwards. This condition, known as strabismus, is not uncommon in children. While it might be a source of concern, there is a path to effective treatment and management.
Our approach at Pediatric Eye Specialists is rooted in compassion and a deep commitment to providing the highest level of care. We are here to guide you and your child through this challenging time with expertise, understanding, and the most advanced medical approaches available. Our team of pediatric ophthalmologists and neurologists works hand-in-hand to diagnose, treat, and manage strabismus, ensuring your child receives comprehensive care tailored to their unique needs.
Prompt evaluation and treatment of strabismus is crucial. Not only can it improve eye alignment and appearance, but it can also enhance vision, support educational development, and prevent secondary conditions like amblyopia. Our approach addresses both the physical and emotional aspects of strabismus, ensuring your child gains confidence along with visual improvement.
Understanding the roots of pediatric strabismus is key to providing effective treatment. Let’s explore the various causes that can lead to this common eye condition in children.
Many cases of pediatric strabismus are linked to genetic predispositions. A family history of strabismus or related eye conditions like cataracts can increase a child’s risk. These genetic links often play a significant role in the development of the condition. If your family has a strong history of amblyopia or strabismus, we would strongly recommend you get your child checked at a young age.
Strabismus in children can also arise from developmental issues. Problems during prenatal development, such as complications or birth defects, can affect the eye muscles or nerves. Conditions like Down syndrome or cerebral palsy are often associated with strabismus. In addition, rarely the use of significant amounts of alcohol or drugs by the mother or the presence of certain in utero infections can have an effect on the visual development of a prenatal child.
Issues with nerves, particularly the cranial nerves that control eye movement, can lead to strabismus. Any damage or dysfunction in these nerves, possibly due to injury or a neurological disorder like a stroke, can result in misaligned eyes. Similarly, abnormalities in the extraocular muscles that move the eyes can cause strabismus.
Certain environmental factors during infancy, such as extreme prematurity or head injuries, can lead to the development of strabismus. In some cases, significant uncorrected refractive errors can also contribute to the condition.
Accommodative strabismus is a type of strabismus often seen in children who are farsighted (or hyperopic). The effort to focus clearly can lead to crossing of the eyes, a condition known as accommodative esotropia. Prescription glasses to correct the refractive error can often resolve this form of strabismus.
Strabismus can sometimes be secondary to other eye conditions, such as cataracts or retinoblastoma. In these cases, the primary eye disease disrupts normal visual development, leading to strabismus.
Understanding the causes of pediatric strabismus is crucial for effective diagnosis and treatment. At Pediatric Eye Specialists, we delve into these factors to provide a comprehensive evaluation and personalized care plan for each child. Our expertise in pediatrics, coupled with the latest research in medical imaging and evaluation techniques, ensures that your child receives the best possible care for their specific needs.
Understanding these causes is vital for Pediatric Eye Specialists in diagnosing and formulating an effective treatment plan for strabismus.
In pediatric strabismus, identifying the specific type is crucial for tailored treatment plans. Here’s a closer look at the different forms of strabismus commonly found in children:
Esotropia
This type involves the inward turning of one or both eyes. This could be referred to as being “cross-eyed.” Often noticed early in a child’s life, esotropia can be constant or variable and may require patching to strengthen the weaker eye or treating with corrective lenses or surgery. If glasses fully correct the condition, the patient has accommodative esotropia. If the glasses partially correct the deviation, the patient may have partially-accommodative esotropia. This condition must be differentiated from a paralytic strabismus (such as a 6th nerve palsy) or other congenital strabismus conditions, such as Duane’s syndrome.
Exotropia
Characterized by the outward deviation of an eye, exotropia may be intermittent or constant. In cases of intermittent exotropia, the deviation may be most noticeable when a child is focusing on distant objects or during moments of fatigue. Treatment could include glasses, patching to strengthen the weaker eye, or surgical interventions.
Hypertropia
This form occurs when one eye turns upward compared to the other. It may not be as easily noticeable as esotropia or exotropia, but can cause significant visual problems. Treatment options include prism lenses (rarely needed in children) or surgery. Causes vary, but can include inferior oblique overaction or dissociated vertical deviations.
Paralytic Strabismus
Caused by a muscle paralysis resulting from a cranial nerve disorder, this type can lead to significant misalignment. It’s crucial to identify the underlying cause for appropriate treatment, which might include surgery or prism glasses.
Sensory Strabismus
This occurs in response to poor vision in one eye, often due to conditions like cataracts. The treatment focuses on addressing the underlying cause to improve vision in the affected eye. If the affected eye’s vision is not able to be improved, surgery is some times offered.
Congenital Strabismus
By definition, a congenital strabismus is present from birth. A congenital strabismus may have an esodeviation (eyes deviate inwards or cross) or an exodeviation (eyes deviate outwards). Congenital strabismus patients are more likely to need surgery to correct the deviation than other types of strabismus types to correct the eye alignment and prevent vision problems.
Secondary Strabismus
When strabismus occurs due to other conditions like retinoblastoma or cerebral palsy, treatment involves managing the primary condition alongside strabismus therapy. A secondary strabismus is a label that means the strabismus is caused by another condition.
Recognizing the signs and symptoms of strabismus in children is essential for early intervention and effective treatment. Strabismus, often characterized by misaligned eyes, can manifest in various physical and behavioral indicators. Here’s an overview:
Misaligned Eyes
The most distinct symptom of strabismus is the misalignment of the eyes. One eye might turn inward, outward, upward, or downward, while the other eye focuses straight ahead. This misalignment could be constant or intermittent, and in many cases, it may switch between eyes. Sometimes an eye may be unable to look a certain direction.
Cross-Eyed Appearance
A noticeable sign of strabismus is when one or both eyes turn inward towards the nose, commonly referred to as being “cross-eyed.” This appearance can be more evident when the child is focusing on nearby objects.
Inconsistent Eye Alignment
Children with strabismus might display varying eye alignment, particularly when switching their focus from near to distant objects or vice versa. This inconsistency can affect their ability to concentrate and perceive depth accurately.
Nystagmus (Rapid Eye Movements)
In some instances, strabismus can be accompanied by nystagmus, (rapid, involuntary oscillation or fluttering movements of the eyes.)
Head Tilting or Turning
To compensate for the misalignment and improve focus, children with strabismus may tilt or turn their heads in a specific direction. This posture helps them use their eyes more effectively. Children that have a strong head positioning preference should be evaluated by a pediatric ophthalmologist to ensure that the head positioning is not caused by the eyes.
Squinting or Eye Covering
Parents might notice their child squinting or covering one eye, particularly in bright sunlight.
Difficulty with Depth Perception
Strabismus can impact a child’s depth perception, making it challenging to judge distances accurately. This difficulty might be apparent in activities that require good hand-eye coordination, such as catching a ball.
Avoidance of Certain Activities
Children with strabismus could avoid activities that strain their vision due to the discomfort or difficulty they experience. However, most children will strabismus are only using one of their eyes to see and may even be unaware of the ocular deviation.
Understanding the nuances of pediatric strabismus begins with a thorough and precise diagnosis.
Here’s how Pediatric Eye Specialists approaches this critical step:
Initial Vision Tests
The diagnostic process starts with basic vision tests to assess visual acuity. These tests help determine how well each eye can see and if there is a significant difference of vision between the two eyes, which is common in strabismus. In younger children, observing which eye is crossing can suggest which eye is suspected of having a worse vision. Matching photos (called Allen figure optotypes) can allow for obtaining vision even at young ages.
Observation of Eye Alignment
Our pediatric ophthalmologists carefully observe the alignment of your child’s eyes. They look for signs of misalignment, such as one eye turning inward, outward, upward, or downward while the other eye focuses on an object. In some cases, photographs taken with a flash from home when a parent sees the deviation can also be helpful.
Corneal Light Reflex Test
Also known as the Hirschberg test, this exam checks where light reflects off the cornea and can indicate whether the eyes are properly aligned.
Cover Test
This simple, effective test involves covering and uncovering each eye while the child focuses on a target. It reveals how the eyes move to pick up a visual target and can be a clear indicator of strabismus. In a child with strabismus, the eyes will typically start to move inwards or outwards when performing this testing.
Refraction Test
Often, strabismus is associated with refractive errors like nearsightedness (myopia), farsightedness (hyperopia), or astigmatism. A refraction test, typically involving the use of a retinoscope, helps determine the correct prescription for glasses, if needed. This type of testing is based on the reflection of light off the retina (the back brain tissue of the eye), thus can be performed on young babies with accuracy.
Eye Movement Evaluation
Assessing the full range of eye movement is essential. This evaluation checks for any restrictions or weaknesses in the eye’s movement that could contribute to strabismus.
Imaging Tests
In some cases, further imaging, such as an MRI or CT scan, may be necessary. These tests help rule out or identify any underlying neurological or structural causes of strabismus.
Slit-Lamp Examination
This detailed examination of the eye’s structures can help identify any associated conditions that might be contributing to the strabismus.
Consultation with Specialists
Depending on the findings, consultations with neurologists or other specialists might be necessary, especially if a systemic or neurological issue is suspected.
Each step of the diagnosis is conducted with utmost care and precision, ensuring that your child receives the most accurate assessment, which is pivotal for effective treatment planning. At Pediatric Eye Specialists, we understand that early and accurate diagnosis is key to successful management and treatment of pediatric strabismus.
Pediatric Eye Specialists offers a comprehensive range of treatment options for pediatric strabismus, tailored to each child’s specific needs:
Glasses or Contact Lenses
Glasses or contact lenses are often the first line of treatment, especially for children whose strabismus is the result of an uncorrected refractive error. By correcting the underlying vision problem, the eyes may naturally align better. In some cases, simply wearing the correct prescription is enough to resolve the strabismus.
Patching Therapy
Patching therapy forces the brain to pay attention to the visual input from the weaker eye, which can strengthen it over time. It’s a traditional and often very effective method, particularly for younger children, and is usually part of a broader treatment strategy that includes other therapies as well.
Pharmacological Treatments
Medications may be used temporarily to adjust muscle function or as a diagnostic tool to better understand the nature of the strabismus. For example, botulinum toxin injections can temporarily paralyze overactive eye muscles, which might help the doctor determine the best surgical approach. Atropine eye drops can be used to either adjust someone into hyperopia glasses or as an alternative to patching in very select children.
Strabismus Surgery
Surgery might involve tightening or loosening the eye muscles to change their position, which can have a dramatic impact on eye alignment. While the prospect of surgery can be daunting, it often results in a significant improvement in both the function and appearance of the eyes.
Prism Lenses
Children rarely have true diplopia (double vision), as a child’s brain quickly learns to “turn off” a deviating eye and only use one eye. While this puts a child at risk of amblyopia in the deviating eye, it does help the child to not have true double vision. However, in older children or a sudden onset of a strabismus, a child could have double vision. Prism lenses may be helpful in these cases. Special prism lenses bend the light entering the eye, reducing the need for excessive eye turning and helping to realign the visual axis. They can be a noninvasive option to provide immediate relief from symptoms like double vision. Prism lenses are the most commonly used tool for our adults with strabismus.
Orthoptic Therapy
Orthoptic therapy can be customized to each child’s specific needs and may include a variety of exercises and the use of specialized equipment. It’s usually overseen by an orthoptist or a pediatric ophthalmologist trained in these techniques.
Eye Muscle Exercises
For the majority of eye conditions, unfortunately, vision therapy has been shown to not be helpful for patients, (and in some cases scientific studies have even found vision therapy to be harmful). In one specific condition, called convergence insufficiency, however, we may recommend eye muscle exercises. These exercises can be done at home or in an optometrist’s office and are designed to gradually strengthen eye muscles. We are happy to further discuss vision therapy with any family that has questions.
Regular Monitoring and Adjustments
As children grow, their vision changes, which means their strabismus treatment may need to change too. Regular checkups with an eye care professional ensure that any adjustments to their treatment plan are made in a timely manner, promoting the best visual development possible. Each treatment plan is developed with a child-centric approach, taking into consideration the child’s age, the type and severity of strabismus, and any underlying conditions. Our goal is to not only correct the eye alignment, but also to support the overall visual development and well-being of your child.
Improved Eye Alignment
One of the primary goals of treating strabismus is to improve eye alignment. Successful treatment, especially when started early, can significantly correct misalignment, leading to a more typical appearance of the eyes.
Enhanced Vision
Treatment often leads to improved visual acuity and, hopefully, depth perception. This is particularly important for children’s overall development and daily activities like reading, playing, and participating in sports.
Reduced Risk of Amblyopia
Early intervention is crucial in preventing or treating amblyopia (lazy eye), a common condition associated with strabismus that can lead to permanent vision loss if left untreated.
Boost in Confidence and Social Interaction
Correcting strabismus can have a positive impact on a child’s self-esteem and social interactions, as it alleviates any concerns related to the appearance of their eyes.
Support for Learning and Development
With improved vision and eye alignment, children may find it easier to concentrate and engage in learning activities, supporting their educational development.
