Herpes simplex keratitis, or eye herpes, is a recurrent viral infection caused by the herpes simplex virus (HSV). Eye herpes is an inflammation of the cornea, the clear dome that covers the front part of your eye. HSV infection can be transferred to the eye by touching your eye after contact with an active lesion such as a cold sore or blister. (Herpes simplex keratitis is not to be confused with herpes zoster ophthalmicus, a condition caused by the same virus that causes chickenpox and shingles.)

Symptoms of Eye Herpes

Eye herpes (also called ocular herpes) can produce painful sores on the eyelid or eye surface and cause inflammation of the cornea. Symptoms of eye herpes often mimic those associated with conjunctivitis and include the following:
  • Pain in and around the eye
  • Redness, rash, or sores on the eyelids, around the eyes, or on the forehead
  • Eye redness
  • Swelling and cloudiness of the cornea
  • Tearing
  • Blurred vision
  • Light sensitivity
  • Discharge

Causes of Eye Herpes

Eye herpes is caused by the herpes simplex virus, the same virus that causes cold sores on the lips and mouth. The National Eye Institute (NEI) estimates that 400,000 Americans have experienced some form of ocular herpes. Studies have shown that once a person develops ocular herpes, they have up to a 50% chance of having a recurrence.

Treatment of Eye Herpes

Mild infections of ocular herpes are usually treated with topical and oral antiviral medication. (It's worth noting that topical steroids can make things worse if antivirals are not part of the treatment.) In severe cases, the infection may spread deeper into the cornea. Recurrent episodes of ocular herpes can cause scarring of the cornea that may lead to loss of vision and possibly blindness.

What You Should Know About Eye Herpes

Eye herpes is the most common cause of corneal blindness in the United States. If you have symptoms of eye herpes, see your eye doctor. If left untreated, eye herpes may cause severe eye damage.
