Strabismus

Strabismus is a condition in which the eyes do not properly align, commonly referred to as crossed eyes or wall-eyed. This misalignment may involve one or both eyes turning inward, outward, upward, or downward. It affects approximately 2-4% of young children and, if untreated, can lead to vision problems such as double vision or amblyopia (lazy eye). Strabismus can be classified based on the direction of misalignment, frequency, and whether it affects one (unilateral) or both (alternating) eyes.

Key Takeaways: Strabismus Explained

• Strabismus affects up to 4% of children, often leading to amblyopia or double vision if left untreated. Early diagnosis is critical.

• Common types include esotropia (inward), exotropia (outward), hypertropia (upward), and hypotropia (downward) — each requiring tailored treatment.

• Causes range from genetic and neurological conditions to uncorrected farsightedness, with increased risk in individuals with Down syndrome or cerebral palsy.

• Treatment options are highly individualized, from glasses and vision therapy to eye patching and surgery.

• Adults can benefit too — 78% of adults report functional and cosmetic improvement after strabismus surgery, debunking the “too late” myth.

• Non-surgical breakthroughs like Botox®, VR-based vision therapy, and prism glasses provide rapid, reversible solutions with minimal downtime.

• Seattle-based care offers leading-edge technologies, including EMG-guided Botox, AI-enhanced therapy, and custom prism lens design.

• Workplace-friendly accommodations like blue-light filtering lenses and ergonomic adjustments support Seattle professionals during treatment.

Types of Strabismus

Strabismus is categorized by the direction in which the eye turns:

• Esotropia: Inward-turning eye (most common in infants)
• Exotropia: Outward-turning eye, often appearing between ages 1-6
• Hypertropia: Upward turning eye
• Hypotropia: Downward turning eye

Strabismus can also be classified as constant or intermittent and may vary in severity from a small to a large-angle misalignment.

Causes and Risk Factors

Strabismus results from abnormal functioning of the eye muscles, nerves, or brain centers that control eye movement. Common causes include:

• Neurological conditions affecting the brain’s control over binocular vision.
• Anatomical problems with the eye muscles that impact alignment.
• Uncorrected farsightedness (accommodative esotropia): Eyes strain while focusing on distant objects, leading to crossing.
• Genetic predisposition: A family history of strabismus increases the likelihood of developing the condition.
• Medical conditions such as Down syndrome, cerebral palsy, or stroke which raise the risk of developing strabismus.

Symptoms of Strabismus

• Noticeable misalignment of the eyes
• Double vision or low vision in one eye
• Tilting the head or frequent squinting
• Eye strain and headaches
• Difficulty making eye contact, which may impact social interactions

Diagnosis of Strabismus

An eye care professional will diagnose strabismus using a combination of tests, including:

• Visual acuity testing to measure clarity of vision.
• Refraction tests to check for refractive errors such as farsightedness.
• Alignment and focusing assessments to evaluate eye coordination.
• General eye health examination to detect underlying medical conditions.

Treatment Options for Strabismus

Treatment for strabismus depends on its severity and underlying cause. Common options include:

• Eyeglasses or Contact Lenses: Can help correct accommodative esotropia caused by uncorrected farsightedness.
• Eye Patching: Used when one eye consistently turns, patching the dominant eye encourages the weaker eye to work harder and regain function.
• Vision Therapy: A personalized program of exercises designed to improve eye coordination, alignment, and focusing abilities.
• Surgical Intervention: In severe cases, eye muscle surgery may be needed to adjust the positioning of the extraocular muscles and improve alignment.

Adult Strabismus: Diagnosis and Treatment Beyond Childhood

Myth vs. Reality: Treatment Timelines

Many adults believe they’ve “missed the window” for strabismus correction—a harmful misconception. Recent AAPOS studies confirm:

• 78% of adults who undergo strabismus surgery report significant functional and cosmetic improvement.

Why Strabismus Develops in Adulthood

Unlike childhood cases, adult-onset strabismus often stems from:

Thyroid Eye Disease (TED)

• affects 25-50% of Graves’ disease patients, causes muscle inflammation/restriction

• #1 cause in Seattle adults over 40

Stroke-Related Damage

• Impacts 15-20% of stroke survivors

• Damages cranial nerves III, IV, or VI

• “Post-stroke vision therapy restored my career.” —James T., Seattle engineer

Neurological/Traumatic Causes

• Head trauma (car accidents/sports injuries)

• MS or myasthenia gravis

• Early intervention is critical for recovery
