Common Keratitis Causes and Risk Factors
Keratitis can be caused by infections or non-infections. Knowing these causes helps prevent and treat the condition.
Infectious Causes
Infectious keratitis comes from bacteria, viruses, fungi, or parasites. Bacterial keratitis is common in contact lens users. Pseudomonas aeruginosa causes about 40% of cases in this group. Wearing contact lenses, poor hygiene, and overnight wear increase the risk.
Other risks include eye injuries, pre-existing eye diseases, and a weak immune system. Viral keratitis can be caused by herpes simplex virus. Fungal keratitis often follows eye injuries with organic matter.
Non-Infectious Causes
Non-infectious keratitis can be caused by many factors. This includes exposure keratitis and chemical injuries. Dry eye syndrome, blepharitis, and systemic diseases like rheumatoid arthritis are also causes.
Long-term use of certain medications, like topical corticosteroids, can also lead to non-infectious keratitis. It’s vital for those at risk to see an eye care professional regularly.
Knowing the causes and risks of keratitis helps prevent it. Good hygiene with contact lenses, eye protection, and managing health conditions are key.
