Herpes zoster, or “shingles,” is a painful viral infection of the nervous system that causes a characteristic rash and blistering usually limited to one side of the body. The rash is associated with the areas of skin served by these same affected nerves. A herpes zoster attack may begin with skin pain, followed by a rash and blisters.
The eye may become involved in herpes zoster infections up to 40% of the time. Vision may become affected and the eye appear red. This may remain a minor superficial inflammation of the cornea, or clear front surface, or may become more severe with deeper involvement. While there are treatments that can be used to attempt to diminish the length, discomfort, and effects of a herpes zoster infection, there is no consistent cure. Scarring and chronic, long-term pain in the affected area can be frustrating complication of this infection. Oral antiviral medications and steroids may be utilized as an aid toward recovery and in an effort to minimize the long-term effects.
When the eye becomes involved, specifically chosen eyedrops will be required to treat your ocular findings. This may include antibiotics, steroids, or even antiglaucoma medications. These medications will diminish, yet not eliminate, the risk of scarring, cataracts and glaucoma, which can follow herpes zoster infections.
