What are corneal problems?
The cornea is the clear dome shaped outer surface which covers the front of the eye, it plays an important role in focusing your vision. It contains no blood vessels so receives nourishment from tears and the aqueous humor (the fluid behind the cornea).
Your cornea acts as a barrier helping protect your eye against germs and dirt that can harm the eye. The cornea also works with the lens to focus light coming into the eye onto the retina and serves as a filter screening out damaging UV light from the sun.
Common problems with the cornea include:
What causes it?
Scarring can be formed as the result of deep injury to the eye, or a corneal disease or disorder.
The causes of keratoconus is unknown. It is however more common in people who suffer with allergies such as hay fever, asthma and eczema and in people with very flexible joints.
Infections cause inflammation of the cornea and can be caused by bacteria, viruses, fungi or parasites. Infection can also be related to contact lens wear – poor cleaning or overuse of contact lenses that should be discarded.
