Keratoconus: Symptoms, Causes & Treatment

What is Keratoconus?

Keratoconus is a progressive eye condition in which the cornea (the clear, dome-shaped surface of the eye) thins and gradually bulges outward into a cone-like shape. This distortion affects how light enters the eye, leading to blurred or distorted vision.

Key Features of Keratoconus:

1. Progressive Thinning: The cornea weakens and becomes thinner over time.
2. Cone Shape: Instead of maintaining a normal, round shape, the cornea bulges out, creating an irregular cone shape.
3. Vision Problems: It causes blurred, distorted vision, sensitivity to light, and difficulty seeing at night.

Who is Affected?

Keratoconus usually starts in adolescence or early adulthood and can progress for 10-20 years. It may affect one or both eyes.

Symptoms of Keratoconus:

• Blurred or Distorted Vision: The irregular shape of the cornea distorts light entering the eye, leading to blurry or wavy vision.
• Increased Sensitivity to Light: Bright lights can cause discomfort or glare, especially at night.
• Frequent Prescription Changes: Eyeglasses or contact lenses may need frequent adjustments as the condition progresses.
• Double Vision in One Eye: Some people experience multiple images or ghosting in a single eye.
• Difficulty Seeing at Night: Night vision becomes challenging, especially when driving.
• Eye Irritation or Redness: Often due to constant eye rubbing or strain.

Early symptoms may be mild, but they tend to worsen as keratoconus progresses.

Causes of Keratoconus

The exact cause of keratoconus is not fully understood, but several factors are believed to contribute to its development. These include:

1. Genetic Factors

• Family History: Keratoconus often runs in families, suggesting a genetic predisposition. Individuals with a family history of the condition are at higher risk.

2. Environmental Factors

• Eye Rubbing: Frequent and vigorous eye rubbing is associated with keratoconus. It is thought that mechanical stress on the cornea from rubbing may contribute to its thinning and protrusion.
  
• Exposure to Allergens: Allergic conditions that lead to eye rubbing or inflammation might be linked to the development of keratoconus.

3. Biochemical Factors

• Corneal Collagen: Abnormalities in the collagen fibers within the cornea may lead to its weakening and bulging. Collagen provides structural support to the cornea, and its dysfunction can affect corneal integrity.

4. Hormonal Factors

• Puberty and Pregnancy: Keratoconus often begins during puberty or early adulthood, a time when hormonal changes occur. There is some evidence suggesting hormonal factors might influence the development of the condition.

5. Other Contributing Factors

• Eye Conditions: Certain eye conditions or diseases may increase the risk of developing keratoconus.
  
• Systemic Diseases: Conditions such as Down syndrome or Marfan syndrome, which affect connective tissue, have been associated with a higher risk of keratoconus.

6. Unknown Factors

• Genetic Mutations: Some researchers believe that specific genetic mutations might play a role, though more research is needed to identify these potential causes conclusively.

Understanding these factors can help in the early identification and management of keratoconus, although its multifactorial nature means that no single cause is definitive.

Diagnosis and Treatment at L.J. Eye Institute

At L.J. Eye Institute in Ambala, keratoconus is diagnosed and managed with a combination of cutting-edge technology and expert care. Here’s how the institute addresses the condition:

Diagnosis

• Corneal Topography: This advanced diagnostic tool creates a detailed map of the cornea’s surface, allowing for precise identification of the corneal shape and any abnormalities associated with keratoconus.
  
• Other Diagnostic Tests: Additional tests may be conducted to evaluate the extent of corneal thinning and irregularities, ensuring a comprehensive assessment of the condition.

Treatment Options

Corrective Glasses and Contact Lenses

• Early Stages: For initial stages of keratoconus, corrective glasses or soft contact lenses can help manage vision problems.
  
• Specialized Contact Lenses: As the condition progresses, L.J. Eye Institute offers specialized contact lenses such as rigid gas permeable (RGP) lenses, scleral lenses, and hybrid lenses to provide better vision correction and comfort.

Corneal Cross-Linking (CXL)

Purpose: This procedure aims to strengthen the cornea and slow the progression of keratoconus. It involves applying riboflavin (vitamin B2) drops to the cornea, followed by exposure to ultraviolet (UV) light.
Benefits: CXL helps to stabilize the cornea and prevent further worsening of the condition.

Intracorneal Rings (ICR)

• Purpose: Intracorneal rings are inserted into the cornea to reshape it and reduce visual distortion. This minimally invasive procedure can improve vision and delay the need for more invasive treatments.
  Procedure: The rings are placed through a small incision, and their placement can be adjusted to optimize visual outcomes.

Corneal Transplant

• For Advanced Cases: In severe cases where other treatments are not sufficient, corneal transplant surgery may be necessary. L.J. Eye Institute offers various types of corneal transplants, including:
  
• Penetrating Keratoplasty (PKP): Replacement of the entire cornea.
  
• Deep Anterior Lamellar Keratoplasty (DALK): Replacement of the front layers of the cornea.
  
• Endothelial Keratoplasty (EK): Replacement of the inner layers of the cornea.

L.J. Eye Institute in Ambala combines advanced diagnostic techniques with a range of treatment options to manage keratoconus effectively and provide personalized care tailored to each patient’s needs.
