Keratoconus is an eye disorder that affects the cornea, the transparent dome-shaped front part of the eye that helps focus light. It is a progressive disorder that starts in adolescence and can cause vision to become distorted or blurred. It affects both eyes, however, one eye may be more severely affected than the other. The exact cause of Keratoconus is unknown, however, it is believed to be the result of a combination of genetic and environmental factors.
What Are the Symptoms of Keratoconus?
The most common symptom of Keratoconus is blurred vision. Other symptoms include:
- Distorted vision
- Increased sensitivity to light
- Halos or starbursts around lights
- Double vision in one eye
- Eyestrain
If you experience any of these symptoms, it is important to see an eye doctor as soon as possible.
What Causes Keratoconus?
The exact cause of Keratoconus is unknown, however, it is believed to be the result of a combination of genetic and environmental factors. Some research suggests that certain activities, such as eye rubbing, may increase the risk of developing Keratoconus. Other research suggests that certain medical conditions, such as allergies or asthma, may also increase the risk.
It is also believed that weak corneal tissue can cause Keratoconus. The cornea is made up of layers of collagen and elastin fibers, which can weaken over time as a result of genetics, environmental factors, and certain lifestyle habits.
How Is Keratoconus Diagnosed?
Keratoconus can usually be diagnosed during a comprehensive eye exam. During the exam, your ophthalmologist will take a detailed look at the shape and thickness of your cornea. This will help them to determine if you have Keratoconus or another eye disorder.
Your ophthalmologist may also use a slit lamp to look for signs of Keratoconus. This instrument shines a bright light into the eye and magnifies the image of the cornea. This allows your ophthalmologist to see any changes in the shape of the cornea.
How Is Keratoconus Treated?
The goal of treatment for Keratoconus is to slow the progression of the disorder and improve vision. Treatment options may include:
- Eyeglasses or contact lenses to correct vision
- Corneal collagen crosslinking to strengthen the cornea
- Intacs to reshape the cornea
- Corneal transplant to replace the cornea
Your ophthalmologist will help you decide which treatment option is best for you.
