Keratoconus is an eye condition that affects the structure of the cornea, which is the transparent, curved layer at the front of the eye responsible for focusing light onto the retina, enabling clear vision. Individuals with keratoconus have a thin cornea that bulges outward, forming a cone shape, which results in blurry and distorted vision.

 

This condition negatively impacts the patient’s ability to perform everyday activities such as reading and driving. In this article, Maghrabi Health's eye experts provide essential information on how to treat keratoconus and manage its symptoms.

 

What is Keratoconus?

 

Keratoconus typically begins at puberty and progresses over the years into the 30s. This condition affects approximately one in every 2,000 people and causes a gradual deterioration of the cornea.

 

The middle layer of the cornea, which is the thickest part, is composed of water and the protein collagen. This structure helps maintain the cornea’s round shape and contributes to clear vision. In keratoconus, this shape is altered, causing the cornea to become irregularly conical, which prevents light from being focused correctly on the retina.

 

Causes of Keratoconus

 

The exact causes of keratoconus are not well understood, but Maghrabi Health experts suggest several factors that may contribute to the development of the condition, including:

 

1. Genetic Factors: A family history of keratoconus increases the likelihood of developing the disease. Studies indicate that approximately 10% of keratoconus patients have a relative with the condition.
2. Chronic Eye Inflammation: Chronic eye inflammation resulting from allergies or exposure to irritants can damage corneal tissue, contributing to keratoconus development.
3. Excessive Eye Rubbing: Frequent and vigorous eye rubbing is a risk factor that increases the likelihood of developing keratoconus and can worsen the condition in those already affected.
4. Certain Health Conditions: There is a known association between keratoconus and certain disorders such as Down syndrome, Marfan syndrome, and Ehlers-Danlos syndrome.

 

Symptoms of Keratoconus

 

In its early stages, keratoconus may cause minor changes in vision, which may go unnoticed by the patient, leading to a delay in diagnosis and treatment. Maghrabi Health eye experts recommend consulting a specialist if one or more of the following symptoms are observed:

 

• Slight blurring of vision.
• Increased sensitivity to light.
• Difficulty seeing at night.
• Eye irritation.
• Headaches caused by eye strain.
• Seeing halos around bright lights.
• The need for frequent changes in eyeglass prescriptions.

 

As the condition progresses, symptoms worsen, making it difficult to perform daily tasks. In advanced cases, the cornea may swell and develop scars, further impairing vision.

 

How Do Maghrabi Health Experts Diagnose Keratoconus?

 

Maghrabi Health specialists diagnose keratoconus through a comprehensive eye exam, which includes the following tests:

 

Corneal Topography: The most accurate method for diagnosing keratoconus. This test creates a detailed map of the cornea’s curvature using computerized imaging, helping to track disease progression. Slit-Lamp Examination: This test helps detect any abnormalities in the structure of the cornea. Pachymetry: This test measures the thickness of the cornea, which helps identify areas of thinning.

 

 

 

 

 

 

 

Keratoconus Treatment at Maghrabi Health

 

The treatment of keratoconus varies depending on the severity and progression of the disease. Early intervention can help slow disease progression and improve the patient’s quality of life.

 

Early-Stage Treatment

 

In the initial stages of keratoconus, vision can often be corrected using eyeglasses or contact lenses. These methods help address common issues such as nearsightedness and astigmatism caused by the irregular shape of the cornea. As the condition advances, rigid gas permeable (RGP) contact lenses may be required to improve vision.

 

Intermediate Stage Treatment

 

For advanced keratoconus, Maghrabi Health specialists use a procedure known as Corneal Collagen Cross-Linking (CXL). This treatment involves applying riboflavin (vitamin B2) eye drops to the cornea and then activating them with ultraviolet light.

 

This process strengthens the corneal structure by forming new collagen bonds, which helps stabilize the cornea and prevent further deterioration. While this procedure cannot restore the cornea to its normal shape, it can slow disease progression and may improve vision in some patients.

 

Advanced Stage Treatment

 

In severe cases where previous treatments are ineffective, Maghrabi Health experts may recommend one of the following options:

 

1. Intracorneal Ring Segments (Intacs): These small, curved devices are implanted in the cornea to flatten its surface, improving vision. This minimally invasive procedure takes about 15 minutes.
2. Corneal Transplant: This surgical procedure involves replacing the damaged corneal tissue with healthy donor tissue. Achieving optimal results from the surgery can take several months, and some patients may still require corrective lenses after the procedure.

 

Can Keratoconus Be Prevented?

 

There is no known way to prevent keratoconus. Maghrabi Health experts emphasize that avoiding harmful habits, such as excessive eye rubbing, can help protect the cornea from damage and deterioration. As with many eye conditions, regular visits to specialized eye centers for routine eye exams are crucial for early detection and management of these conditions, enabling effective treatment with minimal side effects or complications. Individuals with one or more of the risk factors mentioned earlier should prioritize these exams.

A: Although keratoconus can significantly impact vision, it rarely leads to complete blindness. Early diagnosis and appropriate treatment plans help manage the condition effectively and preserve vision.

 

Q: What habits should be avoided if I have keratoconus?

A: Avoid rubbing your eyes, as it can exacerbate the condition and cause further damage to the cornea.

 

Q: Do smartphone screens affect keratoconus?

A: Yes, prolonged exposure to smartphone screens can lead to severe dry eye, which may cause corneal abrasions, worsening the condition.
