What is Keratoconus?
Keratoconus is an eye disease that is characterized by having a cone-shaped cornea. Normally, the cornea is dome-shaped but when the cornea bulges outward like a cone, the light bend as it enters the eye. As a result, blurred vision happens.
Keratoconus is considered as a slow and progressive disease. Hence, it may develop or progress slowly for 10 years or even longer.
Who is at Risk for Keratoconus?
People who are in their teen years and early 20s are at high risk for keratoconus. Still, keratoconus may start in childhood especially if it runs in the family.
Other risk factors include medical problems such as allergic conditions and chronic eye rubbing.
What Causes Keratoconus?
The exact causes of keratoconus remain unknown. However, genetic, environmental, hormonal causes are taken into consideration.
It is believed that a person may have keratoconus due to a familial association. On the other hand, environmental factors such as eye rubbing, allergies, and oxidative stress may also lead to the said disease.
What are the Symptoms of Keratoconus?
Some of the symptoms of keratoconus include the following: blurred vision, distorted vision, night vision problems, eye strain, headache, eye irritation, increased sensitivity to bright light, and worsening of vision.
How is Keratoconus Treated?
An early treatment option for keratoconus would be wearing eyeglasses or soft contact lenses. However, when it progresses, you may need to wear more appropriate lens designs such as gas permeable contact lenses, “piggybacking” contact lenses, and scleral and semi-scleral lenses.
Other treatment procedures are topography-guided conductive keratoplasty and corneal transplant.
