Viral Keratitis: A Threat to Your Eyesight
What is Viral Keratitis?
Viral keratitis is an eye infection that affects the cornea, the clear front surface of the eye. It’s caused by a viral infection, most commonly from the herpes simplex virus (HSV-1).
Symptoms of Viral Keratitis
Symptoms of viral keratitis can vary but often include:
- Eye pain
- Redness
- Excessive tearing
- Sensitivity to light (photophobia)
- Blurred vision
- A feeling of something being in the eye
- Small blisters or ulcers on the cornea
Causes of Viral Keratitis
The most common cause of viral keratitis is the herpes simplex virus (HSV-1), the same virus that causes cold sores. Other viruses, such as adenovirus, can also cause this condition.
Risk Factors
Several factors can increase your risk of developing viral keratitis:
- Weakened immune system: People with weakened immune systems are more susceptible.
- Contact lens wear: Improper contact lens hygiene can increase the risk of infection.
- Exposure to the virus: Direct contact with someone who has an active herpes infection can increase your risk.
