Damage to the cornea may result from entry of foreign particles into the eye and penetrating into the corneal tissue. There are several causes of corneal infections. This article gives information about causes, symptoms and prevention.
Causes of Corneal Infections
These infections may be parasitic, bacterial, fungal or viral. These germs may enter the cornea through different ways. Some of the ways include:
- Contact lenses: If you use lens for longer than the recommended time or if they are worn for long hours, especially when you sleep it can affect the cornea. Using plain water instead of proper solutions to store or wash the lenses may also be one of the reasons for the condition.
- Dust: Dust particles which enter the eye get embedded in the cornea and may cause fungal and bacterial infections.
- Accidental Injury: Wood particles entering into the eyes of carpenters, metal pieces falling into the eyes of factory workers, motor vehicular accidents causing eye injury and infection with infectious microorganisms on the road can cause corneal infection. Even coconut shells flying into the eye or bacterial or fungal corneal ulcers can also be the cause.
- Associated with infections in surrounding area: People with AIDS, diabetes or any other immuno-related conditions can show this infection.

Prevention
- Corneal infections caused by viruses and bacteria can be prevented if you protect your eyes from injury and avoid physical contact with sufferers of conjunctivitis.
- Do not share contact solution, eye makeup, eye drops and lens cases with people who are infected.
- Wash your hands with warm water and soap for 15 seconds at least after contact with the person who is infected.
Diagnosis
An ophthalmologist examines your eye thoroughly in order to diagnose the eye disease.
