Corneal Dystrophies Treatment | Cannon EyeCare Seattle

When your vision becomes cloudy or you experience persistent eye discomfort, it might be more than just aging—it could be corneal dystrophies. At Cannon EyeCare, serving the Seattle area with locations at University Village and Pike Place Market, we combine Midwestern hospitality with cutting-edge expertise to diagnose and treat these complex genetic eye conditions. This comprehensive guide will help you understand corneal dystrophies, recognize symptoms, and discover the advanced treatment options available at Cannon EyeCare in Seattle.

What Are Corneal Dystrophies?

Corneal dystrophies are a group of rare, inherited eye disorders affecting the cornea—the clear, dome-shaped front layer of your eye that helps focus light. These genetic conditions cause abnormal material to accumulate in different layers of the cornea, gradually affecting its transparency and your vision quality.

Unlike other eye conditions that develop due to injury or environmental factors, corneal dystrophies are present from birth but often don’t show symptoms until later in life. They typically affect both eyes symmetrically and progress slowly over the years or even decades. The International Classification of Corneal Dystrophies (IC3D) recognizes over 20 distinct types, each with unique characteristics and treatment approaches.

The Structure of Your Cornea

To understand corneal dystrophies, it’s helpful to know that your cornea consists of five distinct layers:

• Epithelium: The outermost protective layer
• Bowman’s membrane: A thin protective barrier
• Stroma: The thick middle layer (90% of corneal thickness)
• Descemet’s membrane: A thin basement membrane
• Endothelium: The innermost layer that pumps fluid out

Different types of corneal dystrophies affect different layers, which determines their symptoms and treatment approaches.

Types of Corneal Dystrophies: Understanding the Four Main Categories

Epithelial and Subepithelial Dystrophies

These dystrophies affect the outer layers of your cornea and often cause painful corneal erosions—episodes where the surface layer doesn’t adhere properly.

Epithelial Basement Membrane Dystrophy (Map-Dot-Fingerprint Dystrophy)

• Most common epithelial dystrophy
• Typically affects adults aged 40-70
• Causes irregular maps, dots, or fingerprint-like patterns on the cornea
• May cause sudden eye pain, especially upon waking
• Often manageable with lubricating drops and specialized contact lenses

Meesmann Dystrophy

• Appears as tiny cysts in the epithelium
• Usually begins in childhood, but symptoms may not appear until adulthood
• Generally causes mild irritation and slight vision changes
• Treated primarily with lubricating eye drops

Epithelial-Stromal TGFBI Dystrophies

These dystrophies are caused by mutations in the TGFBI gene and involve both the epithelium and stromal layers.

Reis-Bücklers Dystrophy

• Appears early in life with recurrent corneal erosions
• Causes honeycomb-like opacity in Bowman’s layer
• May require specialized treatments or surgery as it progresses

Thiel-Behnke Dystrophy

• Similar to Reis-Bücklers but with distinct patterns
• Often causes significant visual impairment over time
• May benefit from phototherapeutic keratectomy (PTK)

Stromal Dystrophies

These affect the thick middle layer of the cornea and often cause characteristic patterns visible during examination.

Granular Corneal Dystrophy

• Causes crumb-like opacities in the central cornea
• Usually begins in childhood but may not affect vision until later
• Two main types: Granular Type 1 (Groenouw Type 1) and Granular Type 2 (Avellino)
• Advanced cases may require corneal transplantation

Lattice Corneal Dystrophy

• Creates glass-like filamentous lines in the cornea resembling a lattice pattern
• Usually begins before age 20
• Can cause recurrent corneal erosions and progressive vision loss
• Two main types with different genetic causes and presentations

Macular Corneal Dystrophy

• Causes cloudy patches throughout the cornea
• Often begins in the first decade of life
• Generally has a more severe course than other stromal dystrophies
• May require corneal transplantation earlier than other types

Endothelial Dystrophies

These affect the innermost layer responsible for keeping the cornea clear by pumping out excess fluid.

Fuchs’ Endothelial Corneal Dystrophy (FECD)

• **Most common corneal dystrophy requiring treatment
• Affects approximately 4% of Americans over age 40
• More common in women (about 3 times more likely than men)
• Causes corneal swelling, morning vision cloudiness, and eventual corneal edema

Posterior Polymorphous Dystrophy

• Causes abnormal cell growth on the corneal endothelium
• Often asymptomatic, but can progress to require treatment
• May be associated with other eye abnormalities

Recognizing the Symptoms of Corneal Dystrophies

The symptoms of corneal dystrophies vary significantly depending on the type and severity. Many people live with mild dystrophies without ever knowing they have them, while others experience progressive vision problems that significantly impact their quality of life.

Common Early Symptoms

• Blurred or hazy vision: Particularly noticeable in the morning
• Light sensitivity (photophobia): Bright lights become uncomfortable
• Foreign body sensation: Feeling like something is in your eye
• Excessive tearing: Your eyes may water more than usual
• Eye pain or discomfort: Often worse upon waking

Progressive Symptoms

As corneal dystrophies advance, you may experience:

• Worsening vision: Objects may appear cloudy or distorted
• Corneal erosions: Sudden, severe eye pain, often in the morning
• Difficulty with night vision: Halos or starbursts around lights
• Contact lens intolerance: Previously comfortable lenses become irritating

Morning Pain: A Telltale Sign

One characteristic symptom of many corneal dystrophies is eye pain that’s worse in the morning and improves throughout the day. This occurs because your eyes produce fewer tears while sleeping, allowing the corneal surface to dry out and potentially separate from underlying layers.

Advanced Diagnostic Techniques at Cannon EyeCare

At Cannon EyeCare, we use state-of-the-art diagnostic technology to accurately identify and monitor corneal dystrophies. Our comprehensive approach ensures early detection and precise treatment planning.

Slit Lamp Examination

Our high-magnification slit lamp microscopes allow us to examine your cornea in detail, identifying characteristic patterns and deposits that indicate specific dystrophies. This painless examination provides immediate visual information about your corneal health.

Corneal Topography and Tomography

Advanced imaging technology maps the shape and thickness of your cornea, revealing subtle irregularities that may not be visible during routine examination. This technology is particularly valuable for monitoring progression and planning treatments.

Pachymetry

We measure corneal thickness using ultrasonic or optical pachymetry, which is essential for diagnosing conditions like Fuchs’ dystrophy, where corneal swelling is a key feature.

Specular Microscopy

This specialized imaging technique photographs the corneal endothelium, allowing us to count and evaluate the health of the cells responsible for keeping your cornea clear. This is particularly important for diagnosing and monitoring endothelial dystrophies.

Genetic Testing

For confirmed cases or family members at risk, genetic testing can identify specific mutations associated with corneal dystrophies. This information helps with family planning and provides valuable prognostic information.

Comprehensive Treatment Options: From Conservative to Cutting-Edge

Treatment for corneal dystrophies depends on the type, severity, and how much your vision and comfort are affected. At Cannon EyeCare, we offer the full spectrum of treatment options, always starting with the most conservative approaches.

Conservative Management

Lubricating Eye Drops and Ointments

• Artificial tears help maintain corneal surface health
• Preservative-free formulations reduce irritation
• Thicker ointments provide longer-lasting protection, especially overnight

• Complete replacement of the central cornea
• Reserved for advanced cases with multiple-layer involvement
• Longest recovery time, but can restore vision dramatically
• Success rates exceed 90% in most cases

Emerging Therapies: The Future of Corneal Dystrophy Treatment

The field of corneal dystrophy treatment is rapidly evolving, with several promising therapies on the horizon.

Gene Therapy

Researchers are developing gene-based treatments that could address the underlying genetic causes of corneal dystrophies. Recent studies have shown promise for CRISPR-Cas9 gene editing in treating Fuchs’ dystrophy and TGFBI-related dystrophies. While still in clinical trials, these treatments could potentially prevent or reverse dystrophy progression.

Cell Therapy

Innovative treatments using cultivated corneal cells are showing remarkable promise. Companies like Aurion Biotech and Emmecell are conducting clinical trials for injectable endothelial cell therapies that could treat Fuchs’ dystrophy without surgery. These treatments, expected to become available in the next few years, could revolutionize care for endothelial dystrophies.

Regenerative Medicine

Researchers are exploring the use of stem cells and tissue engineering to regenerate healthy corneal tissue. These approaches could provide alternatives to traditional transplantation, potentially eliminating the need for donor tissue and reducing rejection risk.

Living with Corneal Dystrophies: Practical Strategies for Daily Life

While corneal dystrophies can be challenging, many patients lead full, active lives with proper management and care.

Managing Daily Activities

• Use proper lighting: Bright, even lighting reduces strain and improves vision.n
• Protect your eyes: Wraparound sunglasses shield from wind and UV rays
• Stay hydrated: Proper hydration supports overall eye health
• Follow medication schedules: Consistent use of prescribed drops is crucial

Workplace Considerations
