Your cornea is the clear protective layer that's positioned over the front of each eye. Aside from protecting the eye from dust, dirt, and debris, the cornea is also responsible for bending and focusing light. It works in conjunction with the lens of your eye to focus light clearly on your retina. This enables you to see. Sometimes, your cornea may become too thin, causing it to change shape.
When your cornea raises and becomes dome-shaped, this is called keratoconus. This condition causes the light entering your eyes to bend incorrectly, making images appear blurry. Several factors may contribute to keratoconus. Dr. Burd at Burd's Eye View, PC can give you more information regarding the diagnosis and treatment of this eye disorder.
What Causes Keratoconus?
Often, genetics contribute to keratoconus. If others in your family have this disorder, you may be more at risk of developing it yourself. Eye allergies that cause you to rub your eyes excessively may also contribute to keratoconus, so may some tissue disorders such as Marfan syndrome. Usually, symptoms begin to appear in the late teens.
How Do I Know If I Have Keratoconus?
A visit to Burd's Eye View, PC is the safest course of action if you've recently noticed changes in your vision. Through a routine eye exam, Dr. Burd can detect conditions such as keratoconus, but it's important to mention any symptoms you may have. Signs you may have keratoconus include:
- Eyes that are swollen or red
- Blurred vision
- Distorted vision, especially where straight lines appear wavy
- Sensitivity to light
- Sensitivity to glare
- Inability to wear contact lenses due to discomfort
To diagnose keratoconus, your eye doctor will examine your cornea and measure its curvature to determine whether treatment is required.
What Is the Course of Treatment for Keratoconus?
Keratoconus may be treated simply through prescription eyeglasses or hard contact lenses that help to flatten the cornea while you're wearing them. Your optometrist may also be able to reshape your cornea by using a special light and eye drops to strengthen your cornea, causing it to flatten on its own. In more serious situations, your optometrist may recommend surgery, such as a corneal transplant.
