Keratoconus is a condition in which the cornea is not spherical, but protrudes into a cone shape. Corneal cones can cause blurred vision and make patients sensitive to light. Keratoconus usually affects both eyes and usually begins to appear between the ages of 10 and 25. The condition can progress slowly over 10 years or longer.

1. Causes of corneal cones

No one knows the exact cause of keratoconus. However, scientists believe that genetic, environmental or hormonal factors have a more or less influence on the disease.
Hereditary factors for keratoconus :
Some genetic defects cause certain protein fibers in the cornea to become weak. These fibers give the cornea a perfect curvature, when these fibers are weak, the cornea deforms and bulges forward. According to research by scientists, families who have had a person with keratoconus have a high probability that the next generation will also have the disease. Environmental factors:
People with keratoconus often have allergies such as asthma, eczema and food allergies. People with allergies rubbing their eyes too many times can damage the cornea, creating an opportunity for keratoconus.

2. Symptoms of keratoconus

Corneal cone signs and symptoms change as the disease progresses, including:
Blurry or altered vision as the disease progresses Sensitivity to light or bright lights, which may affect to driving at night Frequent need to change glasses Eyes suddenly appear cloudy or severely impaired vision.

3. Complications of keratoconus

Keratoconus is a very dangerous disease due to the great influence of the refractive properties of the cornea (irregular astigmatism). If not treated early, the disease can even progress to blindness.
Patients with the disease will most likely have very weak vision. In addition, wearing clear lenses in keratoconus may not completely correct vision.
You also need to pay attention to the complications of sudden vision loss and corneal scarring due to rapid swelling of the cornea. Scarring of the cornea will make the vision effects more and more severe. And even corneal transplant surgery is needed to help treat the disease.

Thus, keratoconus is a relatively dangerous disease, although the disease progresses slowly, but the consequences are great and can cause permanent vision loss. Therefore, when detecting signs of keratoconus, it is necessary to visit medical facilities with eye specialists for timely examination and treatment.
