Non-infectious Keratitis is usually caused by an injury to the eye. It can also be a result of allergies which affect the eye. Dry eyes can cause the cornea damage and lead to Keratitis, too. Sometimes this is because of a pre-existing eye condition. The types of dry eye Keratitis are:
- Keratitis sicca
- Filamentary Keratitis
- Exposure Keratitis
There are a few risk factors that may predispose an individual to developing either infectious or non-infectious Keratitis. These are:
Wearing contact lenses
Lens wearers are more likely to develop Keratitis than those who do not wear contact lenses. Because of this, if you wear contact lenses make sure that you always wash your hands before putting in or taking out your lenses. You should also make sure that your lenses are properly cleaned and that you do not wear them for longer than your optometrist has recommended.
Medicated Steroid eye drops
The use of corticosteroid eye drops may make you more likely to develop Keratitis. For this reason, use your prescribed medicated steroid eye drops exactly as prescribed by your eye doctor or GP.
Immune system diseases
If you have an immune system disease or are undergoing chemotherapy, there is an increased risk of developing Keratitis.
This last risk factor is purely an environmental one. If you live in a place where the climate is hot and humid on a regular basis, you’re at a slightly higher risk for developing Keratitis.
