What is the Main Cause of Keratoconus?

Keratoconus is a progressive eye condition that affects the shape and clarity of your vision. It occurs when the normally round cornea becomes thin and begins to bulge outward into a cone-like shape. This irregular shape prevents light from focusing properly on the retina, leading to distorted and blurry vision. Understanding the main cause of keratoconus and the importance of early detection is essential in protecting your eyesight and quality of life.
 

Understanding the Main Cause of Keratoconus

While the exact cause of keratoconus is not fully understood, research suggests it results from a combination of genetic, environmental, and biochemical factors. One of the most significant contributors is a weakening of the collagen fibers that help the cornea maintain its shape. When these fibers are compromised, the cornea becomes more susceptible to bulging.
 

Several risk factors may contribute to the development of keratoconus, including:
 

• Genetics: A family history of keratoconus increases the likelihood of developing the condition.
• Chronic eye rubbing: Frequent or aggressive rubbing of the eyes can damage the corneal tissue over time.
• Underlying conditions: Certain conditions such as allergies, asthma, and connective tissue disorders are linked to a higher risk of keratoconus.

The Importance of Early Detection

Keratoconus often begins during the teenage years and can worsen over time if not managed. Because the changes in vision may initially be subtle, many individuals may not seek help until the condition has progressed significantly.
 

Early detection through comprehensive eye exams is crucial. When keratoconus is identified in its early stages, treatment can be more effective in preserving vision and slowing progression. At Canyon Optometry, we use advanced diagnostic tools to detect corneal abnormalities before they become more difficult to manage.
 

Treatment Options for Keratoconus

Though keratoconus cannot be cured, there are effective treatments available to improve vision and slow its progression. Specialty Contact Lenses are often the first line of treatment for patients with keratoconus. Unlike standard contact lenses, specialty lenses such as scleral lenses are designed to vault over the irregular cornea, creating a smooth optical surface and providing clearer vision. These lenses are customized for each patient and are highly effective at improving visual clarity.
 

Other treatment options may include:
 

• Corneal cross-linking: A procedure that strengthens corneal tissue to halt the progression of the condition
• Intacs: Small inserts placed in the cornea to help reshape it and improve vision
• Corneal transplant: In advanced cases, when other treatments are no longer effective, a corneal transplant may be necessary

Protecting Your Vision with Expert Eye Care

If you have a family history of keratoconus or notice changes in your vision such as increased sensitivity to light, difficulty seeing at night, or frequent changes in your eyeglass prescription, it is important to schedule a comprehensive eye exam. Early diagnosis can make a significant difference in managing the condition and preserving your eyesight.
