Herpes Zoster (Shingles)

Shingles are an infection caused by the chickenpox virus. After an initial outbreak of Chickenpox, the virus remains dormant within the nerve cells of the central nervous system. In some cases, sometimes years later, the virus will reactivate in the eye. This can cause painful blisters on the skin and the eye. Treatment may reduce inflammation and scarring in the cornea when the skin around the eye is affected.
