Did you know that one in 2,000 people in the United States is affected by keratoconus? It’s the most common corneal dystrophy among Americans, according to the National Eye Institute. It’s a condition that occurs when your cornea progressively thins out and bulges in a cone shape. Keratoconus doesn’t lead to total blindness, but it can cause significant vision impairment if not treated.
Keratoconus is often diagnosed in teens and young adults. Common symptoms include itchy eyes, double vision, blurry vision, and sensitivity to light. Refractive errors like astigmatism are also indicators that you may have keratoconus. As this ocular condition worsens, it may lead to eye pain and other severe vision problems. To diagnose keratoconus, eye doctors usually conduct several tests, including:
Comprehensive Eye Examination: A complete eye exam is the first step in determining whether you have keratoconus. Your doctor will start by reviewing your medical and health history. Then, they will conduct visual acuity and refraction tests, among others.
Slit Lamp Examination: This will allow your doctor to get a closer look at the different structures of your eye. In a slit lamp exam, your doctor will examine your sclera, cornea, lens, retina, and optic nerve.
Topography and Tomography: These present valuable information on the curvature of your cornea. Topographic maps reveal irregular astigmatism with steepening. Additional parameters are provided by corneal tomography.
Your doctor may also use other techniques to confirm the diagnosis. These are ocular response analyzer and optical coherence tomography.
Treatment for keratoconus will depend on the symptoms you have. For mild cases, wearing a pair of eyeglasses can help with vision correction. Over time, though, you may be prescribed special contact lenses to alter the shape of your cornea. This will help keep your vision in proper focus. Your doctor may also recommend other treatment options, such as:
