24 August 2023

Herpetic keratitis is an inflammation of the cornea, the transparent layer that covers the front part of the eye. This condition is caused by the herpes simplex virus, specifically type 1 (HSV-1) in most cases. Although less common, type 2 (HSV-2) can also be responsible. This virus is highly contagious and can be transmitted through direct contact with an infected person or even through contact with contaminated objects.

Causes of herpetic keratitis

Herpes simplex infection is common and usually manifests as cold sores in the oral region. However, in some cases the virus can affect the eye and cause herpetic keratitis. Risk factors for developing this condition include:

• Previous herpes simplex infection: If you have had oral herpes, you are at higher risk of developing herpetic keratitis.

• Weakened immune system: which can allow the virus to reactivate and cause an eye infection.

• Stress – can weaken the immune system and increase the risk of herpes outbreaks.

• Sun Exposure: Prolonged exposure to ultraviolet radiation can trigger herpes outbreaks in the eye.

Symptoms of herpetic keratitis

They can vary in severity and can include:

• eye pain
• redness
• light sensitivity
• Blurry vision

• eye discharge

Herpetic keratitis is a serious condition that requires immediate medical attention. If you are experiencing symptoms similar to those mentioned above, it is crucial to seek medical attention in order to receive the proper diagnosis and treatment. Maintaining good eye hygiene and preventing the spread of the virus are essential steps to protect the health of your eyes.
