Keratoconus is a condition that causes the cornea, the clear front part of the eye, to become thin and cone-shaped. This can lead to blurry, distorted vision.
What is the cause of keratoconus?
The exact cause of keratoconus is unknown, but it is thought to be a combination of genetic and environmental factors. There is a higher risk of developing keratoconus if you have a family history of the condition. Keratoconus must be inherited from both parents.
What are the signs and symptoms of keratoconus?
The most common symptoms of keratoconus are:
Halos around lights
Difficulty seeing at night
Astigmatism and short-sightedness
Keratoconus symptoms typically develop at 10-15 years old.
How is keratoconus treated?
There is no cure for keratoconus, but there are treatments that can help improve vision. The most common treatments are:
- Glasses or contact lenses: These can help to correct vision in the early stages of keratoconus.
- Corneal cross-linking: This is a procedure that uses ultraviolet light and vitamin B12 to strengthen the cornea. It can help to slow the progression of keratoconus.
- Corneal transplantation: This is a surgery that replaces the damaged cornea with a healthy cornea from a donor. It is the only treatment that can restore clear vision in people with advanced keratoconus.
What should I do if I think I have keratoconus?
If you are experiencing any of the symptoms of keratoconus, it is important to visit an optometrist. Early diagnosis and treatment can help to prevent vision loss.
