What is a Keratoconus?


If you have ever wondered what is Keratoconus, then you are not alone. Many people suffer from the same eye condition. However, the severity of the condition varies between both eyes. It is generally noticed during the teenage years, and gradually worsens over ten to twenty years. Once it affects one eye, it usually doesn’t progress as fast in the other eye, but you may need to change your glasses often.

One classic symptom of keratoconus is monocular polyopia, also known as distorted vision. It is best visible when the eye is exposed to high contrast fields. People with keratoconus see many images of a point of light, and these images are jumbled together in a chaotic pattern. Some individuals may also experience streaking distortion around light sources, and the images move relative to each other in time with the heartbeat.

A full history and comprehensive eye examination is necessary to diagnose keratoconus. A physician may evaluate the external appearance of the eye, and measure the curve. The doctor may also map the surface of the cornea using a special computer, which shows the condition of its surface. Treatment for keratoconus varies. It may be mild or severe, but treatment is usually aimed at correcting vision. A doctor may prescribe eyeglasses, or a special type of hard contact lenses.

The cause of keratoconus is unknown, but there are several risk factors that can increase the likelihood of developing the disorder. People with severe ocular allergies, frequent eye rubbing, and aggressive knuckle rubbing are risk factors. Other risk factors include history of asthma, allergies, Down syndrome, and Down syndrome. However, a genetic risk factor is the most common contributor. If you suffer from keratoconus, it may be worth seeking medical attention.

The most common symptom of keratoconus is blurred vision. In most cases, the cornea of a person with keratoconus has a high refractive error and irregular astigmatism. This distorted vision can often be corrected by glasses, but glasses will not always correct higher-order optical aberrations. Other symptoms include multiple images of the same object. These images are often blurred and overlapping.

There are several types of treatment for keratoconus. Some people can wear contact lenses with some degree of success, but severe cases will require corneal transplant. The goal of surgery is to correct the underlying condition and restore vision. In severe cases, the keratoconus eye condition may require corneal surgery. In this procedure, the diseased cornea is removed and replaced with a healthy donor cornea.

Early keratoconus patients can correct their vision problems with eyeglasses or soft contact lenses. Later on, the condition may require rigid gas-permeable contact lenses to correct the problem. In severe cases, corneal transplant may be the only treatment for keratoconus. These procedures may also be used to treat more advanced cases. However, keratoconus is often treated without surgical intervention.

Early symptoms of keratoconus include increased sensitivity to light. Some people have a high degree of nearsightedness or astigmatism. As the disease advances, the symptoms may get worse, causing double vision or halos. People with keratoconus may need new eyeglasses often. The early stages can lead to vision loss, resulting in a need to replace glasses frequently.

The cornea is the outer most lens of the eye, and acts as a front window. In keratoconus, the outer part of the cornea gradually thins and bulges, resulting in a cone-like shape. When this cone shape develops, light cannot refract properly into the pupil, leading to blurry vision. This disease usually develops slowly, and is most likely to be diagnosed during your teen years. After ten years, the condition usually plateaus.
