Overview of Keratoconus
Keratoconus is an eye condition that affects the structure of the cornea, the clear, dome-shaped surface that covers the front of the eye. In patients with keratoconus, the cornea begins to thin and gradually bulge outward into a cone-like shape. This deformation causes visual impairment as the light entering the eye is not focused correctly, leading to distorted and blurred vision. Symptoms often appear in the late teens or early twenties and might include mild blurring of vision, slight distortion, and increased sensitivity to light.
Causes and Risk Factors
The exact cause of keratoconus is still not fully understood, but it is believed to be linked to a combination of genetic predisposition and environmental factors. Some studies suggest that excessive eye rubbing, a history of poorly fitted contact lenses, and chronic eye irritation may contribute to its development. Additionally, certain allergic conditions such as asthma and eczema are considered risk factors due to the associated inflammation and frequent eye rubbing.
Treatment Options for Keratoconus
Treatment for keratoconus varies depending on the severity of the condition and how quickly the disease is progressing. Here are the most common strategies used to manage and treat keratoconus:
- Eyeglasses or Soft Contact Lenses: In early stages, mild keratoconus can be corrected with eyeglasses or soft contact lenses.
- Rigid Gas Permeable Contact Lenses: As the condition progresses, these lenses may be recommended to help maintain a more normal corneal shape, improving vision.
- Corneal Cross-linking (CXL): This relatively new treatment helps to prevent further progression of keratoconus by strengthening the corneal tissue. It involves the application of vitamin B2 drops to the cornea, which are then activated by ultraviolet light.
- Corneal Transplant: In advanced cases where vision cannot be corrected with lenses and cross-linking is not an option, a corneal transplant may be necessary.
Each treatment option comes with its own set of advantages and considerations. An eye care specialist can provide guidance based on the specific condition of your eyes.
Living with Keratoconus
Managing keratoconus is a collaborative effort between you and your eye care professional. Regular check-ups are essential to monitor the progression of the disease and make timely decisions regarding the best treatment approach. Additionally, protecting your eyes from UV rays and avoiding eye rubbing are practical steps that can help manage the condition.
